Question:
How can I disable alarms verification so that when the I/O driver is disconnected to the field device, for example, the alarms referring to this device are ignored?
Solution:
A possible solution would be to create a link at the AlarmVerify property of the Area containing the I/O tags with information on the device’s connection status. To do so, you can use IOKit’s PhysicalLayerStatus tag, which returns the following values: 0 for disconnected, 1 for connecting, and 2 for connected.
