Detailed information concerning the status of the basic unit and the detected errors can be
called with the programming software. Click the "PLC status information" icon in the menu item
"SPS-Commun. 3".
The data displayed in the status window is updated when the window is opened again.
If error management is performed via programming, the basic unit is able to react to an error
immediately. Suitable immediate measures can be programmed.
Each error is identified by the number of the class it belongs to, an error code within that class
and appropriate arguments. Only one error per class may be stored and detailed by the basic
unit within a predefined group of internal variables.
The user program can access the values of these variables and use them for error
management.
Comment: You can access PLC error information using "PLC status information" in the menu
item "SPS-Commun. 3".
