The RTAC is connected to multiple Modbus devices, need to read all the tags in the RTAC.

Thanks for your help

You can use the Modbus or DNP3 driver. I’ve used both between Ignition and an RTAC. There are advantages to both. If the Ignition DNP3 driver implemented event-based polling, I’d recommend that for all the advantages that DNP3 has over Modbus. But the Modbus driver is free and reliable, so that’s what I’d suggest. If you really need a proper DNP3 driver, then use Kepware at this point.

Created a Modbus server on the Rtac and connected to it, no issue.

Thanks for your input.
