Messages

Overview
Messages are used to indicate events and states in the control process on the
C7-613 display. The messages have to be created beforehand, however
(see Section 4.3.7). A message consists of at least a static text. Fault messages
and operational messages can also contain up to four output variables.
The following different types of messages exist:
• Operational messages
• Error messages
• System messages
Operational/Fault Messages
Operational and fault messages are triggered in the user program by the control
process (see Section 4.6.1). They are specified by the user and contain
process-related information.
System Message
The C7-613 triggers system indications. They are stored in the firmware and
provide information on C7-613 operating modes as well as maloperations or
malfunctions.
