Communication between 2 controllers in different 800xA Systems via Control Network
I am working on a projet for which we have 2 seperate systems; one with a Sil-3 rating(System A) and one with a Non-Sil rating(System B). The System A needs to send data to multiple controllers on the System B system via the ethernet even though they are on different systems(and control networks). Both the control networks shall be housed on a single switch. Sending the data over hardwire is not a possibility due to distance constraints and we would really like to avoid the Client/Server network.
Please guide if this would be possible with IAC or MMS? Would there be any manual which details over how to proceed to establish the communication between the controllers?

Two setting to be defined, TCP/IP forwarding to be enables and y Hop setting needs to be increased from default , if you have more RNRP areas else, other than this no change in CS
and No need to configure any router setting in connectivity servers as long as same series of IP and it falls under RNRP standards. CS will automatically route data between one controller to another controller..
Configuration of RNRP , You can find in networking manuals, Plese find below the details
yes it is possibe. However, The controller should be in same serious of IP range and also should be in same RNRP area.
If both controllers are in different RNPP areas then the MMS data will be routed through connectivity servers.. and you need to configure Connectvity servers are as routers between different range of IP.
One more small question, Why do u want to use SignalAE block.. Why dont you use AlarmCond or AlarmCond Basic.. I always develop Libraries with this blocks and it works fine with alarm control.
If the controllers are in separate 800xA systems and you are using IAC, the compiler can´t resolve the IP-addresses for the controllers and you have to explicit enter the IP-address other the other part. When communicating from SIL3 to Non-SIL, it is also necessary to set Expected SIL for the IAC variable in both applications. In the the Non-SIL application/program the attributes for SIL communication can be edited after selecting Tools/Show SIL IAC Attributes in the editor.
