Hi! Is there an example of a project(PLCnext Engineer) using modbus rtu?

Hi Dmitry, I’ve branched this question from the original conversation, since that was marked as “Resolved”. I hope that’s OK.

There are example projects included with the Modbus RTU library in the PLCnext Store: https://www.plcnextstore.com/permalinks/apps/latest/60002172000014 (see the library documentation for details).

Thanks. I can’t configure the modbus RTU communication. The controller is a slave device. Modbus Poll-the master device. The screenshot shows the settings that I made. The module is AXL SE RS485.
