5.22 Message System
The message system is an integral part of the user interface. Mes-
sages are reactions to events that are communicated to the operator in
an intelligible form. A distinction is made between internally and exter-
nally generated messages, depending on where the event occurred.
The diagram below shows the structure of the message system.

The areas shown in gray color can be freely designed during program-
ming.
5.22.1 Internal Messages
Internal messages are all messages that are generated by the operat-
ing system. A distinction is made between system messages and error
messages. The user (programmer) cannot influence the generation of
these messages.
5.22.2 System Messages
System messages are generated by the operating system as a result of
internal plausibility checks. A system message is activated immediately
after the corresponding event has occurred.
Pending system messages are signaled to the operator
• by a flashing Help key status LED and
• setting the system variable StateHelp to the logical value '1'.
