Hi,
I am setting up a transaction group in order to collect a batch of data on a trigger basis.
I have created a transaction group with the following settings:
Action
Trigger
Options
I have set the group to Read items as the data must be consistent when the trigger fires.
Everything seems working fine except that sometimes Ignition miss the trigger, so I further investigated the communication between Ignition and the OPC Server (Kepware) and I realized that the trigger is not get subscribed as it is described in the manual, instead the trigger is polled like other tags.
The only PublishRequest and Response I found are related to Subscription keepalive that Ignition sets when connection go OPC server.
Am I doing something wrong or it's the standard behavior (so the manual isn't fully right).
Thank you
Davide
