8.14.4 Api object
The Api object represents the root of the PowerMACS API and is the only object in the interface that can
be created, or instantiated, by your client application.

connected to, read and write PLC data and access Process data, such as Cycle data, Trace and Events.
For any method of the Api object to function you must be connected to a PowerMACS target system.
Which TC to connect to is controlled using the property IpAddress. Normally you connect to the system
node, that is, the System TC. However, in order to access the PLC of another station but the first (which
always executes on the System TC) you must connect to the TC on which the station in question runs.
The following methods do only function if connected to the System TC:
If called when not connected to a System TC they will return eRetCmdNotAllowed.
 GetSetup
 SetSetup
 GetSetupItem
 SetSetupItem
