Sorry, I'm very new at Modbus/TCP & PLCs in general.. I'm trying to poll(and in the end read/write to) a register from a Horner X371 PLC, the register identified through Cscape is %R6208.. Would that register be a normal holding register? (use FC 3 to poll)? ..
I can get to some other registers, but I cannot seem to poll this one.
(writing code in perl MBclient & tried in 'Simply Modbus TCP client')
Thanks,
Ben
