Trevor J Posted June 23, 2020 Report Share Posted June 23, 2020 Is there a system integer or bit that is set when a Modbus RTU SLAVE has received a command from a master? I would like the make a watchdog on my slave device to to notify the operator if communications is lost and to pause the process as it is working with stale data.
