I am trying to establish communication between the atlas copco gateway and deltav via modbus but this seems futile. I did set the deltav with the correct baud rate parity etc but still no luck. I even tried it in both master and slave mode.

In master mode the error received from diagnostics indicated no communication and bad integrity as well as Bad Dev.

In slave mode Dev was Good but integrity bad with the error response: 5% communication error

Can you please assist

Hello N_J;

I am afraid that this is a Siemens forum, specializing in Siemens automation equipment and networks.

Can you not find support from Emerson (DeltaV) or better Atlas Copco on communications between the two systems?

Hope this helps,
