I have been given the task of integrating DAQFactory with other HMI's (Weintek) on a system. There are currently 6 communicating with each other over their global data transfer feature which is all working as it should. What i need to do is have one of these screens send a signal to my DAQFactory program to then set a flag on its connected PLC. In reverse order i also need to send an analog signal (flow meter) from my DAQFactory program to the Weintek screen. Is this at all possible? any help would be very appreciated.
I'm attempting to get coil status from a Click PLC from port #2 RS232 to the serial port on the PC. I'm running DAQ Factory Starter Release 16.3. DAQ is set to communicate through the serial port with Modbus RTU master to the PLC. The Com port setup appears to be identical, but the Alert that is coming up is: P-ModbusRTU 0010: Timeout with C1038 Timing lag, data acquisition stalled. Resetting timing: 1.000, offset: 0.000. I'm just getting familiar with this software and when completed I would like the PC to control a telescope and observatory so I'm going to need several I/O points going to and coming from the Click PLC. Any help would be appreciated.
