Installation

Prerequisites

A method of installing NuGet packages as described by the Microsoft Package Consumpion Workflow.

.NET

To use in a .NET application include the following in the target source files:

using JohnsonControls.Metasys.BasicServices;

Option 1: Consume the package by adding a PackageReference.

Add the following to the project's .csproj file:

<ItemGroup>
    <PackageReference Include="JohnsonControls.Metasys.BasicServices" Version="<target version>" />
</ItemGroup>

Option 2: Consume the package by installing on the command line. This workflow shows how to use the nuget.exe CLI (command line interface).

Open a command line and navigate to your project's main directory.

Execute the following command:

nuget install JohnsonControls.Metasys.BasicServices -OutputDirectory packages

Update all packages with the command:
```
nuget restore
```

COM (Component Object Model)

Use the one click setup provided with the release tag to install the required dependencies in your system and register the COM DLL. Keep in mind that for developing purposes the solution is already configured to register with the COM interop when the project is built. Alternatively, you can manually register or unregister the DLL use the RegCOM.bat and UnregCOM.bat scripts located in the Scripts directory.

To manually register for COM interop you can also use the Regasm.exe (Assembly Registration Tool) or similar tool. See more information here.

Excel and Visual Basic for Applications (VBA)

LegacyMetasysClient allows you to interact with your Metasys server from a VBA application using COM interop. To get start, enable the Developer Tab in Excel from the menu File-->Options-->Customize Ribbon. See more information here. Finally, from the Developer Tab click the Visual Basic button to open the editor and add the reference to the Metasys Services Object Library from the references list. See more information here.

Usage (.NET)

This section demonstrates how to use the MetasysClient to interact with your Metasys server from a .NET application. There is an example on Github that can be run from the command line and a specific prototype of an API to API integration about a Weather Forecast application.

Creating a Client

To create a new client and connect to a Metasys server with the default settings use:

var client = new MetasysClient("hostname");

There are four optional parameters when creating a new client:

ignoreCertificateErrors: If your server does not have a valid certificate the MetasysClient will not behave as expected and will likely block the connection. Setting the ignoreCertificateErrors = true will ignore this error and make an insecure connection with the server. To avoid this problem ensure the Metasys server has a valid certificate.

WARNING: You should not ignore certificate errors on a production site. Doing so puts your server at risk of a man-in-the-middle attack.
apiVersion: if your server is not a current 10.1 Metasys server or later this SDK will not function correctly. The version parameter takes in an ApiVersion enumeration value that defaults to the most current release of Metasys. For Metasys 10.1 the api version is v2, for Metasys 11 the api version is v3, for Metasys 12 the api version is v4 and for Metasys 13 the api version is v5.
cultureInfo: to set the language for localization specify the target culture with a CultureInfo object. The default culture is en-US.
logClientErrors: set this flag to false to disable logging of client errors. By default the library logs any communication error with the Metasys Server in this path: "C:\ProgramData\Johnson Controls\Metasys Services\Logs".
timeout: to set the timeout (in seconds) of the https requests. The default timeut value is 300 sec.

Example: the following code shows how to create a client that ignores certificate errors for a v12 Metasys server with Italian translations of values:

CultureInfo culture = new CultureInfo("it-IT");
var client = new MetasysClient("hostname", true, ApiVersion.v4, culture);

In some cases you may want to enrich logs with more specific messages to your application. Typically, you disable internal library logging and catch Metasys Exceptions to be handled in your own logging framework or in use for Log4Net initializer provided by the library. The file log4Net.config allows you to customize settings such as the file path, size, append mode, etc. To create a client with default settings that does not log errors use:

var client = new MetasysClient("hostname", logClientErrors: false);

To log your own errors with Log4Net initializer provided by the library use:

// Initialize Logger with your context Class
var log = new LogInitializer(typeof(Program));            
try
{
    // Your Try logic here...
}
catch (Exception ex) {
    log.Logger.Error(string.Format("An error occured - {0}", ex.Message));
}

See the following examples to change the API version and/or hostname after creating a client, keep in mind that changing one of these properties resets the access token and a new login is required.

// Changing Api version after creating a client
var client = new MetasysClient("hostname",version: ApiVersion.v3);
client.Version = ApiVersion.v2;

// Changing Metasys Server after creating a client
var client = new MetasysClient("hostname");
client.Hostname = "WIN2016-VM2";

After creating the client, to login use the method TryLogin. The signature has two overloads: the first uses the Credential Manager target to read the credentials, whilst the second takes a username and password. Both signatures take an optional parameter to automatically refresh the access token during the client's lifetime. The default token refresh policy is true. See more information here on how to use Credential Manager. If something goes wrong while accessing a Credential Manager target, MetasysClient raises a CredManException. Keep in mind that Credential Manager is available on Windows and is not going to work on other platforms. However, MetasysClient Class could be extended by developers to implement different secure vaults support.

Notice: when developing an application that uses a system account always logged without user input, the preferred way to login is to store the username and password in the Credential Manager vault.

// Automatically refresh token using plain credentials
client.TryLogin("username", "password");

// Do not automatically refresh token using plain credentials
client.TryLogin("username", "password", false);

// Read target from Credential Manager and automatically refresh token
client.TryLogin("metasys-energy-app");

// Read target from Credential Manager and do not refresh token
client.TryLogin("metasys-energy-app", false);

// Sample of a valid access token returne by the previous methods:

    "Expires": "2020-05-12T14:18:51Z"
}
*/

In case you need to get a new access token then use the method Refresh before the token expiration time.

client.Refresh();

To get the current access token (e.g. to use it in an different HttpClient) use the method GetAccessToken.

client.GetAccesToken()

To get the current date & time of the server you can use the method GetServerTime.

client.GetServerTime()

Localization of Metasys Enumerations

To get automatically translated enumerations from a Metasys server you have to use the method Localize.
Note that you must specify the culture during client creation, or set the "Culture" property before using the "get" methods.
The default language for translations will be the machine's current culture (see more information here) or en-US (American English) if the language is not supported (see Supported Localization Languages).

client.Culture = new CultureInfo("it-IT");

Enumerations returned from a Metasys server will be in a format similar to: "reliabilityEnumSet.reliable". MetasysClient has a method to translate these enumerations manually. This method can be very useful if using an external HttpClient since Metasys servers do not hold translation information.

// Access from the client object
string translated = client.Localize("reliabilityEnumSet.reliable"); // Reliable

// Access without instantiating a client
string translated = ResourceManager.Localize("reliabilityEnumSet.reliable",
    new CultureInfo("it-IT"));  // Affidabile

Note: If an automatically translated value (such as Variant.StringValue) contains an enumeration value and not a translated string there could be an error with the MetasysClient globalization setup.

If the enumeration key is desired over the translated value use the EnumerationKey attribute. For example, the translated Variant.Reliability has the enumeration key under the attribute: Variant.ReliabilityEnumerationKey. See the documentation of each Model for more information.

Metasys Objects

Get Object Id

In order to use most of the methods in MetasysClient the identifier (Id) of the target object must be known.
This Id is in the form of a Guid and can be requested using the method GetObjectIdentifier given you know the 'Fully Qualified Reference' (FQR) of the object:

Guid objectId = client.GetObjectIdentifier("Win2016-VM2:vNAE2343996/Field Bus MSTP1.VAV-08.ZN-SP");
Console.WriteLine(objectId);
/*        
d5d96cd3-db4a-52e0-affd-8bc3393c30ec
*/

Get a Property

In order to get a property you must know the Guid of the target object and then you can use the method ReadProperty. An object called "Variant" is returned when getting a property from an object. Variant contains the property received in many different forms. There is a bit of intuition when handling a Variant since it will not explicitly provide the type of object received by the server. If the server cannot find the target object or attribute on the object this method will throw a MetasysHttpNotFoundException.

Variant property = client.ReadProperty(objectId, "presentValue");
Console.WriteLine(property);
/*        
{
    "StringValue": "72",
    "StringValueEnumerationKey": null,
    "NumericValue": 72.0,
    "BooleanValue": true,
    "ArrayValue": null,
    "Attribute": "presentValue",
    "Id": "f1469e25-c46c-5009-b92e-d82603e742a4",
    "Reliability": "Reliable",
    "ReliabilityEnumerationKey": "reliabilityEnumSet.reliable",
    "Priority": "0 (No Priority)",
    "PriorityEnumerationKey": "writePriorityEnumSet.priorityNone",
    "IsReliable": true
}
*/

To get multiple properties from multiple objects in one action use the method ReadPropertyMultiple. This can be very useful if the objects all are of the same type or have the same target properties.

List<Guid> ids = new List<Guid> { id1, id2 };
List<string> attributes = new List<string> { "name", "description", "presentValue" };
IEnumerable<VariantMultiple> results = client.ReadPropertyMultiple(ids, attributes);
VariantMultiple multiple1 = results.FindById(id1);
Console.WriteLine(multiple1);
/*
{
    "Id": "d5d96cd3-db4a-52e0-affd-8bc3393c30ec",
    "Variants": [
    {
        "StringValue": "ZN-T",
        "StringValueEnumerationKey": "ZN-T",
        "NumericValue": 0.0,
        "BooleanValue": false,
        "ArrayValue": null,
        "Attribute": "name",
        "Id": "d5d96cd3-db4a-52e0-affd-8bc3393c30ec",
        "Reliability": "Reliable",
        "ReliabilityEnumerationKey": "reliabilityEnumSet.reliable",
        "Priority": null,
        "PriorityEnumerationKey": null,
        "IsReliable": true
    },
    {
        "StringValue": "Zone Temperature",
        "StringValueEnumerationKey": "Zone Temperature",
        "NumericValue": 0.0,
        "BooleanValue": false,
        "ArrayValue": null,
        "Attribute": "description",
        "Id": "d5d96cd3-db4a-52e0-affd-8bc3393c30ec",
        "Reliability": "Reliable",
        "ReliabilityEnumerationKey": "reliabilityEnumSet.reliable",
        "Priority": null,
        "PriorityEnumerationKey": null,
        "IsReliable": true
    }
    ]
}
*/
Variant multiple1Description = multiple1.FindAttributeByName("description");

Write a Property

In order to write a property you must have the Guid of the object and know the attribute name and type and then you have to use the method WriteProperty.

Guid id = client.GetObjectIdentifier("siteName:naeName/Folder1.AV1");
client.WriteProperty(id, "description", "This is an AV.");

To change the same attribute values of many objects use the method WritePropertyMultiple.

List<Guid> ids = new List<Guid> { id1, id2 };
// Write to many attributes values using a list of tuples
List<(string, object)> attributesList = new List<(string, object)> { ("description", "This is an AV.") };
client.WritePropertyMultiple(ids, attributesList);

// Write to many attributes values using a dictionary of attribute/value pairs
Dictionary<string, object> attributesDictionary = new Dictionary<string, object> { { "description", "This is an AV." } };
client.WritePropertyMultiple(ids, attributesDictionary);

Get and Send Commands

To get all available commands on an object use the method GetCommands. This method will return a list of Command objects. The ToString() method is a useful tool to display the available commands and any information associated with it.
When sending a command the Command.CommandId attribute is used as the parameter:

List<Command> commands = client.GetCommands(objectId).ToList();
Command command = commands.FindById("Adjust");
Console.WriteLine(command);
/*                        
{
    "Title": "Adjust",
    "TitleEnumerationKey": "commandIdEnumSet.adjustCommand",
    "CommandId": "Adjust",
    "Items": [
    {
        "Title": "Value",
        "Type": "number",
        "EnumerationValues": null,
        "Minimum": null,
        "Maximum": null
    }
    ]
}
*/

When sending a command there may or may not be a single value or list of values that needs to be sent with the command. The property Command.Items will list all of these values as Items which contains the Title and Type of the value to change. If the type of an Item is "oneOf" this indicates the values is an enumeration and the possible values will be contained in the EnumerationValues list. Keep in mind the values to be sent in the command is the TitleEnumerationKey not the Title. The Title is the user friendly translated value that describes the enumeration. For example, an "AV Mapper" object has the following commands:

"Adjust" that accepts a number value to adjust the present value.
"TemporaryOperatorOverride" that accepts the value to adjust the present value, the hours, and the minutes for the temporary adjustment.
"Release" which accepts two enumeration values for the attribute and new priority level.

The values on the Commands will model the following:

Command adjust = commands.FindById("Adjust");
Command operatorOverride = commands.FindById("OperatorOverride");
Command release = commands.FindById("Release"); 
Console.WriteLine(release);
/*                        
{
    "Title": "Release",
    "TitleEnumerationKey": "commandIdEnumSet.releaseCommand",

To send the command use the method SendCommand as showed in the follwing samples:

var list1 = new List<object> { 70 };
client.SendCommand(objectId, adjust.CommandId, list1);

var list2 = new List<object> { 75 };
client.SendCommand(objectId, operatorOverride.CommandId, list2);

var list3 = new List<object> { "attributeEnumSet.presentValue", "writePriorityEnumSet.priorityNone" };
client.SendCommand(objectId, release.CommandId, list3);

Get Children

To get the child objects of an object use the method GetObjects.
This method requires the identifier (Guid) of the parent object and an optional number of levels to retrieve. The default is 1 level or just the immediate children of the object. Depending on the number of objects on your server this method can take a very long time to complete.

Guid parentId = client.GetObjectIdentifier("WIN-21DJ9JV9QH6:EECMI-NCE25-2/FCB");
// Get direct children (1 level)
List<MetasysObject> directChildren = client.GetObjects(parentId).ToList();
MetasysObject lastChild = directChildren.LastOrDefault();
Console.WriteLine(lastChild);

Usage (COM)

This section demonstrates how to use the LegacyMetasysClient to interact with your Metasys server from a VBA application. Download the Command Line sample project here and finally the Excel App is available at this link.

Creating a Client

To create a new client and connect to a Metasys server with the default settings use the ComMetasysClientFactory:

Dim clientFactory As New ComMetasysClientFactory
Dim client As LegacyMetasysClient
Set client = clientFactory.GetLegacyClient("host")

There are three optional parameters when creating a new client:

ignoreCertificateErrors: If your server does not have a valid certificate the LegacyMetasysClient will not behave as expected and will likely block the connection. Setting the ignoreCertificateErrors = true will ignore this error and make an insecure connection with the server. To avoid this problem ensure the Metasys server has a valid certificate.

WARNING: You should not ignore certificate errors on a production site. Doing so puts your server at risk of a man-in-the-middle attack.
apiVersion: your server must run at least Metasys v10.1 or later otherwise this SDK cannot be used. The version parameter takes in an ApiVersion string value that defaults to the most current release of Metasys. For Metasys 10.1 the api version is V2.
cultureInfo: To set the language for localization specify the target culture with the ISO Language Code string. The default culture is en-US.
logClientErrors: Set this flag to false to disable logging of client errors. By default the library logs any communication error with the Metasys Server in this path: "C:\ProgramData\Johnson Controls\Metasys Services\Logs". <cr/>

Example: the following code shows how to create a client that ignores certificate errors for a v12 Metasys server with Italian translations of values:

Set client = clientFactory.GetLegacyClient("host", true, "v4", "it-IT")

In some cases you may want to enrich logs with more specific messages to your application. Typically, you disable internal library logging and catch Metasys Exceptions to be handled in your own logging framework or Log4Net configuration provided by the library. The file log4Net.config allows you to customize settings such as the file path, size, append mode, etc. To create a client that does not log errors use:

Set client = clientFactory.GetLegacyClient("host", true, "v4", "it-IT", false)

After creating the client, to login use the method TryLogin.
this method requires a username and password parameters.
<cr/> To login using the Windows Credential Manager use the method TryLoginWithCredMan that requires, as 'target' parameter, the name of the credential defined in Windows.

Dim token As IComAccessToken
'Login passing username and password
Set token = client.TryLogin("user", "password")

'Login using username/password from Credential Manager vault
Set token = client.TryLogin("vault-target")

Metasys Objects

Get Object Id

In order to use most of the methods in LegacyMetasysClient the id of the target object must be known. To retrieve the identifier of an object use the method GetObjectIdentifier.
This method requires the Fully Qualified Reference (FQR) of the object and returns the id as a string (in the form of a Guid).

Dim id As String
id = client.GetObjectIdentifier("siteName:naeName/Folder1.AV1")

Get a Property

In order to get a property you must know the Guid of the target object and then you can use the method ReadProperty. An object called "ComVariant" is returned when getting a property from an object.

Dim result As ComVariant
Set result = client.ReadProperty(id, "presentValue")

Dim stringValue as String
stringValue = result.StringValue

Dim numericValue as Double
numericValue = result.NumericValue

Dim booleanValue as Boolean
booleanValue = result.BooleanValue

Dim ids() As String
ids = Split("id1,id2", ",")
Dim attributes() As String
ids = Split("name,description", ",")
Dim results() As Object
results = client.ReadPropertyMultiple(ids, attributes)
Dim id1 As IComVariantMultiple
Set id1 = results(0)
Dim variants() As Object
variants=id1.Variants

Write a Property

In order to write a property you must have the Guid of the object and know the attribute name and type and then you have to use the method WriteProperty.

Dim id As String
id = client.GetObjectIdentifier("siteName:naeName/Folder1.AV1")
client.WriteProperty id, "description", "This is an AV."

To change the same attribute values of many objects use the method WritePropertyMultiple.

Dim ids() As String
ids = Split("id1,id2", ",")
Dim attributes() As String
attributes = Split("name,description", ",")
Dim attributeValues() As String
attributeValues = Split("AV,This is an AV", ",")
client.WritePropertyMultiple ids, attributes, attributeValues

Get and Send Commands

To get all available commands on an object use the method GetCommands. This method requires the identifier of the object an returns a list of 'ComCommand' objects. When sending a command the 'ComCommand.CommandId' attribute is used as parameter.

When sending a command there may or may not be a single value or list of values that needs to be sent with the command. The Command.Items property will list all of these values as Items which contains the Title and Type of the value to change. If the type of an Item is "oneOf" this indicates the values is an enumeration and the possible values will be contained in the EnumerationValues list. Keep in mind the values to be sent in the command is the TitleEnumerationKey not the Title. The Title is the user friendly translated value that describes the enumeration.
To send the command use the method SendCommand as showed in the following sample:

Dim parameters() As String
parameters = Split("offonEnumSet.0,", ",")
client.SendCommand id, "OperatorOverride", parameters

To get all the available enumeration sets you can use the method GetEnumerations.
This method returns a list of 'ComMetasysEnumeration' objects.

Get Enumeration Values

To get all the values of an enumeration set you can use the method GetEnumerationValues.
This method requires the name (identifier) of the enumeration and it returns a list of 'ComMetasysEnumValue' objects.

Create a Custom Enumeration

To create a new custom enumeration set you can use the method CreateCustomEnumeration.
This method requires the name of the new custom enumeration and the list of values will be associated to the new set. It does not return values.

Edit a Custom Enumeration

To modify the name and/or the values of an existing custom enumeration set you can use the method EditCustomEnumeration.
This method requires the identifier of the existing custom enumeration and the new list of values to be associated. It does not return values.
Note this method cannot be used to add/remove values (it can only modify them)

Replace a Custom Enumeration

To replace the whole definition of an existing custom enumeration set you can use the method ReplaceCustomEnumeration.
This method requires the identifier of the existing custom enumeration and the new list of values to be associated. It does not return values.
Note you can not replace a two-state enumeration with a multiple-state enumeration. Nor can you replace a multiple-state enumeration with a two-state enumeration.

Delete a Custom Enumeration

To delete an existing custom enumeration set you can use the method DeleteCustomEnumeration.
This method requires the identifier of the existing custom enumeration and it does not return values.
Note this method can only delete custom enumerations.

Streams

Reading Object PresentValue COV

To define a stream in order to read the presentValue (COV) of a single or multiple objects use the method StartReadingStreamCOV.
This method requires the object Id (in case of single value) or an arrary of Ids (in case of multiple objects).
To retrieve the value(s) updated by the stream use the method GetStreamCOV or GetStreamCOVList (in case of multiple objects).
To retrieve the array of 'Request Ids' use the method GetStreamRequestIds
To stop reading (and updating) the values use the method StopReadingStreamCOV.
The event StreamCOVValueChanged is fired when a new value has changed and red by the stream.

Collecting Alarm Events

To define a stream in order to collect a list of alarm events use the method StartCollectingStreamAlarms.
To retrieve the list of the alarms collected from the stream use the method GetAlarmStreamEvents.
This method requires, as parameter, the max length of the list of alarms (by default the value is 100).
To stop collecting alarm events use the method StopCollectingStreamAlarms.
The event OnStreamAlarmOccurred is fired when a new alarm has occurred and reported by the stream.

Collecting Audit Events

To define a stream in order to collect a list of audit events use the method StartCollectingStreamAudits.
To retrieve the list of the audits collected from the stream use the method GetAuditStreamEvents.
This method requires, as parameter, the max length of the list of audits (by default the value is 100).
To stop collecting audit events use the method StopCollectingStreamAudits.
The event OnStreamAuditOccurred is fired when a new audit has occurred and reported by the stream.

Keep the Stream Alive

Normally all the methods that define a new stream also keep the stream alive despite the duration of the access token.
In case you want to force it then use the method KeepStreamAlive.
