Hi all; I use wincc 7.4 to indicate the status of pumps (ON, OFF) .PLC s7-300 cpu313c, it is connected remotely to the computer via wireless device. Some time when the power fail accured at plc side, the PC stays in the same status of pumps. although all pumps and PLC are stopped .my question how can i avoid this problem? in other word i need the pc indicate blank sign (not stoped and not running) when the communication is lost. ------------------------------------------------------------------------------------------ |
