Hi All,
Just wondering if anyone can offer some help or point me in the right direction in regards to Modbus communications between a Micro820 and ML1100 PLC.
I have no hardware for testing at this stage and limited experience using CCW so I can only make assumptions...
What I want to do is pass data from a ML110 to a Micro820 via Modbus RTU then read this and additional data from the Micro820 by a PC via Modbus TCP/IP.
From my limited knowledge I have figured that the Micro820 has a Modbus Map that could be written to by the ML1100 over Modbus RTU using MSG commands I could then set up a PC to read data from this same Modbus map using Modubs TCP/IP.
Before going out and buying the hardware I just want to confirm this is the right way to do it as I wont have a lot of testing time.
Any suggestions and information as to how to set this up would be much appreciated.
Cheers All
