I am using edge 8.0.16 with S7-1200 driver.
I have several int,bool and string tags, all of them are able to read/write successfully.
However, when i start to add another string address with the format:
All the current tags have their quality changed from good to bad. And this newly added tag is having bad quality as well. I tried to force a string value to the PLC from the tag provider, and surprisingly it is able to write to the plc, even though the quality is bad.
I tried to create/duplicate an entire new set of DB address, which includes STRING16.254, i.e:
And this time round, all the tags’ quality are showing good, including the newly added string tag.
I am confused why using DB100 is creating the error, and DB101 is not?
i have tried [PLCNAME]DB100,STRING272.254 as well, and it is working… It seems that [PLCNAME]DB100,STRING16 itself is having problem?
Below is the error log:
