how can I solve the problem, which is shown as Modbus exception response 2 (illegal data address) in lookout protocol driver?

[serf408]

I have a Dynisco UPR700 instrument that has a modbus communication protocol, I use the lookout protocol driver modbus to communicate with it, but the lookout protocol driver gave me the information about "modbus exception response 2 (illegal data address)", how can I solve this problem? where can I set the right data address? Thanks!

Most likely you are trying to access a datamember address that is either not supported or non-existant on the UPR700.

Double check the address that you are writing/reading and make sure that it is supported.
