Hi~Everyone!!
This is a simple sketch of our PLC structure.
About the PLC communication, I know between PLC1-1 and PLC1-2 can use IPC flags to communicate byte by byte via 923C (PLC2-1 and PLC2-2 is same).
But I don't understand how to communicate between PLC1 and PLC2 via CP143? And how to exchange data between PLC and HMI via CP143?
I know the special function about communication (OB200~OB205) from the 948 manual. But it just describe how to communication via 923C.
And if PLC2 sent a data to PLC1(the data is DB? DW?.....sorry,I don't know my PLC sent what? In the comment, it just say that is communication data from other PLC. ). How can I find the data in PLC1 and PLC2 ?? I guess the data has different name in PLC1 and PLC2......
Hope you can explain more detail about the PLC communication for me, and if I am wrong ,thanks your correction. Thank you , Thanks!!
