Hi Everyone,
i was hoping for a little help with this module. i have data that needs to be read from a different plc through the Modbus plus network. the manual says that i need to use an ADDM block and a Read_Var block. so i set the address for the ADDM to 'Machine{192.165.1.5}3'. the Modbus proxy is Node 3, i am trying to read a register 40809 from another plc through two bridges that is also Node 3. to give the routing M340 (192.165.1.1) to Proxy(192.165.1,5), Proxy (node 3) to bridge A (node 8) to Bride B (node 9) to plc i need data from (Node 3). i have tried doing the routing following the example from the manual which shows an address of 'CPU_CoPro{192.168.1.50}2'. the routing table shows Destination Index 1 with a route of "Modbus Plus Routing Index" of (1) 13 (2) 6 (3) 22. i am assuming that the 22 is a misprint being that they reading through two bridges nodes 13 and 6 from a plc on node 2. All i get is an error code of 7.
i have tried addressing the ADDM to 'Machine{192.165.1.5}8.9.3' and i still get the error code. i have tried putting the routing to index 3, same problem. i can look at any other node on the local network without any errors. if anyone has an idea of what I'm doing wrong i would greatly appreciate some guidance.
Thanks
