Parameters
Alarm Filter Time
This feature allows you to choose a Signal Delay for the Fault and Overload alarms. This value sets the AlarmFilter0-2 members in the AB:1797_OB4D:C:0 module-defined data type of the configuration tag. Select a value (in milliseconds) by which to filter the transition from On to Off or from Off to On. The Alarm Filter Time values in milliseconds are: 0.25, 0.5, 1, 2, 4, 8, 16, and 32. The default is 0.25ms.
Reset Alarms
When the check box is checked the ResetAlarms member is set to 1. When transitioning from 1 to 0, the alarms reported in the Input module-defined data type are reset (cleared). The alarms are reset even if the alarms are latched, as controlled by the LatchAlarms element in the Output module-defined data type. If the error condition exists when ResetAlarms is invoked the alarms in the input data type are immediately set again. By default the Reset Alarms check box is Unchecked.
