Message Handling - Siemens OP5 Equipment Manual

Message Handling

Message types
Incidents and states in the control process are shown in message form on the
OP display. A message consists of static text as a minimum. If required, vari-
ables are integrated into a message.
The following types of message are displayed on the OP:
Event and alarm
Event messages and alarm messages are initiated by the PLC. They are con-
messages figured and contain process-related information. You have to acknowledge
alarm messages.
System messages
System messages are initiated by the OP. They are not configured. They pro-
vide information on operating states of the OP or maloperations and break-
downs in communication.
Issued event messages and alarm messages are stored in separate message
buffers on the OP. Messages contained in the buffers can be displayed or out-
put to a connected printer.
