I have a remote outstation linked back to a central scada via a VPN and the central scada dials out sms alarms via an RV50. VPN is a bit shaky, drops out occasionally but always re-establishes itself.
Occasionally, alarms conditions occur in my remote PLC while the link is down. When the link is re-established the alarm appears in Ignition but fails to send an sms.
I have worked around this by adding an active delay to all my alarms, but surely this isn’t correct default behaviour? Am I missing something?
