Hey guys, I’m having a hard time understanding how to convert the Node ID in UA Expert into a Channel Browse Path. I’m trying to make my B&R PLC see OPCUA tags in an OMRON PLC. This is what my OMRON tag looks like in OPCUA: [image] What would the Node ID look like if it was a channel browse path…

The browsepath implementation needs everything all the way from the “root” so the screenshot you provided is not enough. Can you take a screenshot of the tree structure to the left as well? In general terms you need to specify “BrowseName” for every step all the way from root. Here are some example…

Ok, here’s how far I’ve gotten. This is my tree structure for the OMRON tag, and the info for Main_PLC: [image] Here’s the info for GlobalVars: [image] And finally, test (Please mind the extra tags that were created): [image] From this information, here’s my interpretation of the path: /0…

Hi, I’m not a expert for OPC UA, but from the UAexpert screenshots, I would try: 0:Root/0:Objects/4:Main_PLC/3:GlobalVars/4:test [image] [image] [image] I think, the “4:&:&” inside the B&R string is because of the support of so called “application modules”, and has to be left out on the omron …

Hmm, that didn’t work. [image] If I could get anyone else to confirm that: 0:Root/0:Objects/4:Main_PLC/3:GlobalVars/4:test is the correct path, I could see if the issue could be coming from somewhere else.

Hi, For me it’s the correct path, to build it use go on every node from the root to your node in UaExpert, then check the BrowseName. WIth this get the number and the name then separate them by a : add a / if you need to add something behind. I think the problem is from another thing. On the scree…

Update: we’re one step closer. [image] I had to update the security mode and security policy to match the OMRON OPC settings, and add the BNR to a trusted client in sysmac. I’m still trying to find what the error code 2158690304 is, but at least my Module is now ok. I kind of suspect the error c…

Error code are by default in decimal but OpcUa error code in AS Help are in Hexadecimal. So error code 2158690304 = 0x80AB0000 (Bad_InvalidArgument) link to the online help page B&R Online Help You can check the logger to have both errors ? The error count is 2.

About certificate you can add an SSL configuration for OPCUA in the configuration view ( B&R Online Help ). You can add a SSL configuration in the opcua_any security configuration ( B&R Online Help ) But to debug opcua_any I would recommend first to test without SSL config and certificate

I don’t think any of these errors are related to the OPCUA_ANY device. My ETH is IF3 so ya. [image] I’ve also tried searching Opc related terms to see if the warnings contain any information, but no luck with that as well. I’ll be trying out the certificates, as I don’t really know which argument…

For the errors in the logger, you have a difference between your hardware configuration and real hardware on the PLC. You have configure a X20BR7300io and it’s not plugged on the real hardware. So it’s no related to opcua_any. Based on the screenshot, if you can connect on UaExpert with same parame…
