7.5 Printing Messages
You can print alarm and event messages
as a direct message log (refer to section 7.5.1),
as a full printout of the message buffer (refer to section 7.5.2),
upon buffer overflow (refer to section 7.4.1).
7.5.1 Direct Message Logging
Event and alarm messages can be printed upon arrival and departure (alarm
messages upon acknowledgment, too) if this was set when the message was
configured. System messages are not logged directly.
If direct message logging follows another print function, the header of the
direct message log is re-printed.
If the printer is disabled, not ready or assigned to another print function, up to
16 messages are stored temporarily. Temporary storage of the messages for
the message log is independent of the message buffer concerned.
You can activate and deactivate direct message logging online at the OP via
the standard screen System Settings
Printer. You do this by selecting the
symbolic input field Message log in the list of parameters and setting the
value ON or OFF.
The table below shows the interdependency between the settings on the OP
and the settings configured in ProTool.
