9. DCS Interface Module The DCS Interface module sends and receives data from the DCS The DCS Interface module sends and receives data from the DCS Messages are loaded from and stored to memory in the DCS I.M. Messages are loaded from and stored to memory in the DCS I.M. DCS Interface Enable Reset Safety Message R/W Monitoring Message Address Data Profibus or Ethernet 16 32

10. DCS Interface Module The RCUs are slaves, but they can generate interrupts to the DCS The RCUs are slaves, but they can generate interrupts to the DCS The DCS interface devices should work in safety mode with power on the signal cable. The DCS interface devices should work in safety mode with power on the signal cable. Any request from the DCS should by answered by the RCU within a deterministic time frame, even if the answer is “I am busy”. Any request from the DCS should by answered by the RCU within a deterministic time frame, even if the answer is “I am busy”. A Safety message from the DCS will interrupt the RCU Master. A Safety message from the DCS will interrupt the RCU Master. A Monitoring Message is handled the requested RCU resource is available A Monitoring Message is handled the requested RCU resource is available
