Determine Network Status Override
The network status override parameter controls whether local logic
should control outputs when it detects a network error condition. You
determine if the network status override is enabled or disabled.
When the override is disabled (default), the device turns outputs off
under any of the events. If the override is enabled, the device ignores
any network fault. If DeviceLogix functionality is enabled, the control
of outputs is maintained even if there is a network fault.
The Network Status Override parameter is used to override normal
behavior during the following events.
