This structure contains elements that chronicle the Program Invocation’s activity and can be used to aid in the diagnosis of Program problems.
Note The original ProgramDiagnosticDataType had flaws. To avoid collisions with existing implementations, a new version with name ProgramDiagnostic2DataType has been created.
Its composition is defined in Table 11.

|
createSessionId |
NodeId |
The CreateSessionId contains the SessionId of the Session on which the call to the Create Method was issued to create the Program Invocation. |
|
createClientName |
String |
The CreateClientName is the name of the Client of the Session that created the Program Invocation. |
|
invocationCreationTime |
UtcTime |
The InvocationCreationTime identifies the time the Program Invocation was created. |
|
lastTransitionTime |
UtcTime |
The LastTransitionTime identifies the time of the last Program state transition that occurred. |
|
lastMethodCall |
String |
The LastMethodCall identifies the last Program Method called on the Program Invocation. |
|
lastMethodSessionId |
NodeId |
The LastMethodSessionId contains the SessionId of the Session on which the last Program Control Method call to the Program Invocation was issued. |
|
lastMethodInputArguments |
Argument[] |
The LastMethodInputArguments provides the input arguments on the last Program Method call. |
|
lastMethodOutputArguments |
Argument[] |
The LastMethodOutputArguments provides the output arguments on the last Program Method call. |
|
lastMethodInputValues |
BaseDataType[] |
