cjbassman2 Posted August 9, 2017 Share Posted August 9, 2017 Hi, I've setup DAQFactory as a Modbus TCP slave. I can write values OK using an external Modbus TCP master. The problem I have is that I'm trying to replicate a certain PLC functionality as below:- 1. Master writes data to slave (DAQFActory/PLC) 2. Slave process the data 3. Slave indicates to master that data has been processed by setting data values to zero. 4. Master is reading registers and detects data has gone to zero so sends next set of data. This works great on a PLC but I cannot fathom how to get a DAQFactory sequence to be able to set the RTU slave data channels to zero. Can you offer a solution please?
