Flexy 205 - Send Notification On IO Server Issue

How do I monitor a PLC’s (in this case a Wago 750-841 so MODBUS) network availability/status? I’ve set up values to tags in the PLC that have static values (+408194 which has a static value of 65535 and +408193 which has a static value of 0) and I can monitor those and get alarm notifications if I manually change those values. But when the Status/Quality of those values goes unknown (your red exclamation point) I don’t get any notification. What am I missing? Is there a better way to monitor the status of a PLC (any brand of PLC) than watching values?
Thanks.

You can use the STATUS tag of the IOServer to monitor the communications. Basically when the tag is anything other than a 1 communications are down to your device.

The nice thing is the STATUS tag is treated the same as any other tags meaning you can set up alarms or notifications based on this tag.
