My end goal is to have data that Ignition is currently reading made available to another device (PLC). Is it possible to have the modbus drive act as a TCP slave, or to have all the tags be written out to specific registers on the other device in bulk (at the device config level, not writing a script for each tag inside Vision).
The driver only acts as a master.
You could add the other slave device as a device in Ignition and periodically read from the first and write the results into the 2nd with a gateway timer script or something.
Can the data that Ignition is reading, be published as “MQTT” data? If so “Open Automation Software” probably would have a driver for your PLC that could subscribe to an MQTT Broker.
Just a thought.
