Hi all

Has any one had any experience with writing the modbus messages using the msg command within RS Logix

When writing or reading the addresses within the lexium error code 83h is returned (invalid Data)

If the communication settings are changed then the no response alarm is returned, so i am assuming comms is ok.

The micrologix substitutes 1 from the decimal address set, but i do not no whether the Lexium adds this one back to the address.

TIA

Post details about the configuration of your MSG instruction, like exactly which Modbus register number you are attempting to read. Posting the *.RSS file itself is a good alternative to screenshots or descriptions.

The Lexium 05 is a Telemechanique servo drive. The Modbus user manual is here: 1760981.pdf
