Hi all,

As you see the attached images,there are too many PLC process control messages and operator message class in our wincc messages list. (Short term and long term messages.)

these messages take up a lot of space in message list and we cannot see the old alarms. How do we get these messages to come only once?

our system is PCS7 V9.1

thank you.

Thank you for your answer Techno_Taru.

But i dont want to block messages. I want to change the frequency of alarms. As you see in the example, same alarm came multiple times in one minute. Can I change this setting if possible?

thank you.
