General
The following messages are generated during execution of an SFC in the AS:
● Operator requests for transitions
● Step errors
● Status messages relating to the SFC status
Only the step error messages require acknowledgment.
Generation of process messages
The messages are generated generically. In addition to the messages, specific mechanisms
are stored which allow direct access to the picture the message pertains to. The corresponding
SFC faceplate will be opened if the block list does not contain a picture.
If you insert an SFC status display in a graphic display, the messages of the associated SFC
are entered in the hierarchy of the group display.
Process messages in the runtime system
The WinCC message system archives and displays the transition and step error messages
for operator requests.
The message system allows you to open the detail view of the associated SFC for an SFC
message and the "Properties" dialog box for the relevant step and transition (button: "Loop In
Alarm").
Operating messages in the runtime system
If you are controlling the process of an SFC a message is generated for each action and
entered into the operation list.
