13.14.4 Message signals in DB 2
DB 2 allows the user to display the messages for individual signals on the operator panel. As the lists of interface
signals show, signals are divided into predefined groups. When a message occurs, disappears or is
acknowledged, the number entered in the message number column is transferred to the HMI. Text can be stored
in the HMI for each message number.
References:
• Lists sl (Book2), see Section "PLC-Messages (DB 2)".

Note
The number of user areas can be parameterized via FB 1.
After the configuration has been modified (FB 1: MsgUser), DB 2/3 must be deleted.
