We will release a new nrComm Lib with function 2 (read input status) and function 4 (read input registers) at this week.


It's not so simple after all ??

I tested the new version 9.40 with a EBM Papst fan. Function 4 doesn't work, it times out. When I connect the fan with "Modbus Poll" from the Modbus tools website, function 4 is working with this fan. So the fan complies to the standard, nrComm not ?

Okay, found out that "TnrModbus.InitPacketsByAddress" is missing declarations for the new functions !!!
So you didn't test it with real equipment ??
