Siemens SIRIUS 3RK3 - Overview of Possible Incoming and Outgoing AS-I Signals

Con󹪝guration and addressing of simulated AS-i slaves
The addresses of the simulated non-safety-relevant AS-i slaves can be freely assigned. The AS-
i slave addresses are assigned in the Safety ES in the properties for the 3RK3 central unit. This is
also where the pro󹪝le of the simulated slave is selected. The simulated slaves are displayed in
italics in the subsystem.
Note
The addresses cannot be changed during runtime because it would require modi󹪝cation of the
con󹪝guration data. That is why no addressing and no address changes can be performed on the
MSS 3RK3 using the addressing device.
Con󹪝guring the safety logic
The parameterizable safety logic of the MSS 3RK3 with AS-i interface allows the following signals
to be interconnected in Safety ES via input and output terminals:
• Inputs and outputs of expansion modules, if supported by the 3RK3 central unit
• Inputs and outputs of the DP interface
• Inputs and outputs of real, non-safety-related AS-i slaves
• Inputs and outputs of real, safety-related AS-i slaves
• Inputs and outputs of simulated, non-safety-related AS-i slaves
• Inputs and outputs of simulated, safety-related AS-i slaves
6.5.5 Overview of possible incoming and outgoing AS-i signals
The information that can be read by the AS-i bus or written to the AS-i bus is displayed in the logic
interconnection in the Safety ES software through terminals.
