Hello,

I am taking my first steps in PLC programming and fault-tracing, so please bear with me.

We have an application, where we use the 1510SP CPU and the TP700 Comfort HMI.

The error messages that we want to be displayed on the HMI work as expected.

However, we also have a notification of 84 "blank" error messages, that we have to acknowledge every time we start up the system.

Any idea where to look for this and disable them?

Hello!

Which alarm class have you configured (error, warning, no acknowledgment..)? Please note that the alarm class defines the acknoledgment model, among others.

I suggest you to follow the next manual Configuring Messages and Alarms in WinCC (TIA Portal) – Extension with S7-1200/S7-1500 

Good luck with that!
