Hi, I have noticed that sometimes when I have downloaded changes a couple of times some of the opc ua variables is not updated. The plc variable and read opc variable in ua expert has different value.
The HMI webserver project has also a strange behavior, different objects seems to get the same tag connection.
Has someone else experienced this behavior? I had to reboot the plc to make it work again. I’m using a RFC 4072s. Best regards Stefan
Hello Stefan, could you upload your PLCnEng project, please. I’ ll check this behavoir. For uploading data to the ShareFile server, please use the following server link: https://phoenixcontact.sharefile.eu/r-rf06a5b174e44ecf8 Please give me following additionally information:
1. Release/FW Stand of used RFC 4072 controller and PLCnEng IDE
2. Names of OPC/HMI Variables, which shows the described behavoir.
Thanks & Best Regards
Eduard
Hi Eduard, The project is the same as in this topic https://www.plcnext-community.net/index.php?option=com_easydiscuss&view;=post&id;=2704&Itemid;=221⟨=en so I think you already have the project.
It feels like it is random variables that is not updated. I have made a simple GUI in HMI web server. In page OPC the objects seems to get the same tag connection when this problem occurs. The fw is 2019.6 on the RFC and I’m using 2019.9 right now but the same problem occurs in previous versions. After some investigation I think it happens when you add variables or structure to a structure OPC tag and then make a download changes. Hope you can replicate the problem. Best regards Stefan
