i have my Freyr SCADA DNP3 simulator, I wanted to connect it with ignition as DNP3 outstation and connection is successful, but I have a problem, tags values are only sent at the beginning of the connection and then it’s not updated even if it’s changed from outstation
Get a Wireshark capture and see if the simulated device is sending any events or value changes on subsequent integrity polls.
Will it update if you restart the tag? Also, how is your tag group set up? I think if you have the rate set to 0 ms, the tag group will not execute.
I’m using default tag group!, restarting doesn’t do anything!
Update: writing to dnp3 outstation sim is successful !, it’s updating in sim but it’s not updating in ignition and tag retain its old value!
Share the pcap file. That screenshot doesn’t look normal.

i hope it’s working, this my first time with wireshark
In your Ignition DNP3 device config, try disabling "auto time sync", and also set the "unsolicited event classes" field to empty.
Scroll down and look for a checkbox, it's in the Advanced category. If you don't have it then you need to upgrade.
it’s added in version 8.1.39, i using 8.1.38
wow, i upgraded to v8.1.49 and disabled it and it worked!
thanks
i just curious to know how you found it from wireshark file?
Your simulator is setting the NEEDS_TIME bit but doesn't seem to support either of the commands being used to try to set its time. Your capture is just full of attempts to sync the time, which has to be done before the rest of comms start.
