Modbus RTU Slave
Posted: Tue Sep 23, 2014 3:20 pm
Hi,
We have an A12 panel setup as a Modbus RTU slave.
If the master sends a write register request (40000 reference address),
but specify a non-zero offset, and a number of registers, the data does not appear to get placed in the associated tags. For example if we want to
transfer some registers starting with reference address 40150, an offset
of 150 would be specified.
If a zero offset is used, it seems to work ok.
Regards,
Ken
