Format string failure On various PLCs I recently experienced the problem that multiple errors appear every second in PLCnext Engineer (2021.3, build 4.9.232.0). The error is ‘Format string failure’. If I double-click on the error, he won’t show anything. If I right-click on the error and then choose ‘Help’, nothing happens. The only solution seems to be a Type 1 reset. After that, I put back exactly the same software and the problem will not occur for the time being. A while later (± 1 day) again. In the Output.log I don’t see anything crazy (no ERRORS). I use HW02 and FW2021.0.5LTS[attachment]String Format.png[/attachment]
Is there any anwser on this.
I am using a new plc, with only one digitial input configured. And i also see the same error.
Hello Killua Zoldyck,
This was a duplicated ticket.
There was an answer to this:
Hello ,could be an application issue for an wrong format of an converting to string FB.
To see where this error appers go in PLCnext in the cockpit and activate stop by string failure.
