Modbus RTU and TCP

This means that the communication problem is not between LM and the Modbus device but further down the line. This error can be returned by a TCP-RTU gateway when a certain RTU device cannot be reached. Increasing the timeout might help but this has to be done not on LM side but on the Modbus device.
