Determines whether hardware alarms for disabled IO devices will be displayed or suppressed.
Allowable Values:
-
0 - (Suppress hardware alarms)
-
1 - (Display hardware alarms)
Default Value:
1
Note:
-
On the Plant SCADA machine that is configured as an IOServer and a client, Plant SCADA will display an initial hardware alarm once to indicate that the device has been disabled and its state is offline. This is true if you only disabled the IO device on the IOServer only by calling IODeviceControl(x, 1,1). Plant SCADA will not display additional hardware alarms for disabled devices if the parameter [IOSERVER]HWAlarmOnDeviceDisable = 0 is set.

On the Plant SCADA machine that is configured as a Control Client only, Plant SCADA will display an initial hardware alarm once to indicate that the device state is offline. Plant SCADA will not display additional hardware alarms for disabled devices if the parameter [IOSERVER]HWAlarmOnDeviceDisable = 0 is set.

On the Plant SCADA machine that is configured as an IOServer and a Control Client, if you disabled the IO device on both the IO Server and the Plant SCADA Control Client (by calling both IODeviceControl(x, 1,1) and IODeviceControl(x, 0,1)), Plant SCADA will not display an initial hardware alarm for the disabled IO device. Plant SCADA will not display any additional hardware alarms for disabled devices if the parameter [IOSERVER]HWAlarmOnDeviceDisable = 0 is set.
