Hello,

I would like to know what the reliability and stability of the new DNP3 driver has been, looking at the topic's the DNP3 legacy driver was around in 2015, and the new DNP3 driver came out with Ignition 8.1.36 in February 2024.

We are looking to use ignition talking to a SEL RTAC using the new DNP3 driver. We have used ignition with the other drivers with no problems. The customer is concerned that DNP3 driver is quite new, and that ignition is better suited to OPC UA.

Has anyone used it in their system if so, what has been the experience good or bad?

Also, what is the size of the DNP3 tags count you are reading through the new DNP3 driver.

Regards

Scott

Seen plenty of this combination so far.

Not sure what this means.

Check out this customer project that uses the DNP3 driver with SEL RTAC:

The customer had a comment that ignition was better suited to using a OPC UA link between the SEL RTAC and Ignition, OPC UA was used internally by Ignition

OPC UA is well supported by Ignition, but the OPC UA implementation on the RTAC is immature.

You should test both, but you may find DNP3 works better.

Ok, Kevin thanks for the update, the customer was just after some feedback/reassurance on the DNP3 driver if it stable and mature. They had asked if it we had used it before and we had to say no, we have used ignition on other projects but had not used DNP3.

The new driver has been out for quite a while, and it is a much better experience than the legacy DNP3 driver, I would not hesitate to use it. If you do run into issues or have feedback, please reach back out!

You asked about tag counts, and I don't have any specifics for this driver (or any driver), but the underlying dnp3 implementation is quite fast. I don't suspect you'll see worse performance with this driver than any other.
