Parameters > Citect.ini File Parameters > IOServer Parameters > [IOServer]WatchDog


Determines whether CitectSCADA periodically checks the communication connection to your standby I/O devices. If you set this parameter to 1, CitectSCADA will check the Standby devices every watch time (as specified by the WatchTime parameter of the device driver). If you set this parameter to 0, this periodic checking is disabled, but CitectSCADA will still communicate with the I/O device on startup to verify that the connection is valid.

Note: If you disable periodic checking, you will not receive a hardware error if the standby I/O device becomes inoperative when CitectSCADA is communicating with the Primary.
