Dear Members,
I am using AB PLC with MVI56-MCM to read data from modbus address 40100-48100 from ABB Drive. How could I do it with one MVI56-MCM as it is mentioned that Read register Count limit to 5000 registers only? I only need about 30 readdata only, 2 of them are from address 48xxx.

Thanks.

As far as I know, you have to call the Modbus address for it's value, and it replies with that value. So in you're case, you have to call only those 30 readdata addresses.

Hope this helps...
