Yes and no. Ignition’s OPC drivers have a poll rate (tag group pace). If something changes in the PLC and back inside that poll window, Ignition itself will not see that change. PLC code is needed to trap and hold such events for external consumers. That is a fundamental attribute of all PLC comms.
Ignition’s Vision client has a separate poll rate it uses to get tag changes and push notifications (in project properties) from the gateway. Tag changes that change back within this additional window will also be missed at the Vision client. Consider running the appropriate processing in a gateway tag change event instead of a client tag change event.
