RSC documentation

This is a reference of the available documentation regarding the RSC services that are built into the PLCnext Runtime System.

Note: From firmware release 2022.0 LTS on, some RSC services can also communicate via gRPC. The respective protocol buffer definitions (.proto files) can be downloaded from our GitHub repository where you find on all about using gRPC in PLCnext Technology.
