Hey all. I have a PC running iFIX talking to a 5555 CLogix processor collecting data. This data is reported for the DNR, so it is imperative that it is collected each day. THe PC is not located near the line I am pulling the data from, so operators cannot visually see that iFIX is running. I wanted to have iFIX send a signal to the PLC 100% of the time that it is running on the PC. The problem I am having is that the PLC will not "see" the bit go to zero since when the computer is shut off etc, it does not actually write a zero into the PLC. Has anyone done anything like this before? I basically need to find a way to "write" a zero into the PLC bit when the computer is shut down. I'm stumped for the time being. \
