I have a problem with the OPC tags of a Siemens S71500 plc. In the first (trial) project (7.9.10) it worked perfectly, but we have bought a license and install the 8.0.5 version on our company server but there is no connection with the tag. I have export the tags in 7.9.10 and import the tags in 8.0.5. There is a connection with the OPC ua server and with the plc. It is the same plc and tag what is used in the projects but it only worked with the 7.9.10 version. I have made a screenshot.
