RSC (Remote Service Calls)

Function extensions can communicate with the PLCnext Technology core components via the RSC interface. You can access various functions and data items via the interfaces.

For example, you can gain read and write access to the Global Data Space (GDS) data using the IDataAccessService RSC service. 

You have the option of using the already registered RSC services of the SDK via the ServiceManager. 

The ServiceManager acts as the RSC API and is used to request services.
