Hi We have Ignition Edge installed on a moxa switch which is connected to a Modbus TCP device. I created a device under config\>Opcua\>Devices. Everything is working fine. Every now and then if I power cycle the whole panel (Edge device + Modbus device), my tags change to “Bad\_NotConnected”. If I then go to config\>Opcua\>Devices I see the device is connected. If I then go to config\>opc\>OPC Quick client, I can drill down to the device and r/w any value without any issues. The problem is that all my tags stay “Bad\_NotConnected” until I restart the edge device or re-enable the device under config\>Opcua\>Devices (sometimes) or restart the opc ua module. It is as if the GW eventually makes connection to the Modbus device but the tags don’t. Any Idea what could cause/solve this issue? I did set Max Retry Count = 10 (config\>Opcua\>Devices\>MyMBDevice\>edit) but that didn’t seem to help. ---

If I need to include any additional information, please let me know. The issue is that this system is going to be running on a remote site from the end of this week and if for some reason a power loss/cycle occurs on site, I will have to remotely login and reset whatever is needed to get all the opc tags to become healthy again. ---

Ignition Edge Version 8.1.3 And module drivers are shown below: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/4/84c76bc1c3149d10573743414c2673eb1427bf5f.png) ---

Hmm. 8.1.5 includes a fix for something that sounds a bit like this… ---

I went and took a look at the changelog the only thing I could see maybe relating to the issue was the following: ## Connectivity **2044: TCP Driver can saturate shared execution engine if many devices are defined and unavailable** To prevent saturation of the shared execution engine thread pool, the TCP Driver now uses the opc-ua-executor thread pool to connect. But since 8.1.4 is the current stable build and since this system is now up and running, would it be best if I wait for 8.1.5 stable build? ---

Hmm, you’re right, I don’t see the entry I’m talking about. I’m trying to find out why it’s not there. ---

Are you thinking of the Allen Bradley driver issue instead? ---

No, we missed a couple change log entries. The one I'm thinking of will read something like this: > Fixed a bug that caused tags to get stuck with Bad\_NotConnected or Uncertain\_InitialValue quality on startup or reconnect. ---
