    Abstract: A system and a method for safety relevant input to a control system, the control system including a PLC which includes a non-safety control module for controlling non-safety processes, and a safety control module for controlling functional safety of processes, the system further including an operator panel for user selection of safety-related object input, wherein the system includes two communication paths between the operator panel and the safety control module, that each of the communication paths uses a different communication protocol, that each communication path goes through the non-safety control module to and from the safety control module, that the first communication path transfers object code and the second communication path transfers masked object code.
