8 Log

8.1 Introduction

February 2012
The log serves as a troubleshooting aid.
There are 4 MB of process memory available for this purpose.
Error messages and keystrokes are recorded in the process memory.
When the code number LOGBOOK is entered and the soft key EXECUTE pressed, the log entries are
copied from the process memory into an ASCII file on the control's hard disk and are displayed.
Note
If you want to perform tests and to view the new entries in the log, you have to call the log again.
NC error messages are distinguished by an N, PLC error messages by a P before the error number
and the error text.
The sources of the keystroke inputs are entered in INFO: MAIN KEYSOURCE: <source>.
A <Source> may be:
- KEYBOARD
- PLC
- PLCNCSTART
- HANDWHEEL
- LSV2
Note
In the log, the first horizontal soft key (at bottom left on the screen) is recorded as soft key 0, the
second soft key as soft key 1, etc.
The first vertical soft key (top right on the screen) is recorded as V soft key 0, the second soft key
as V soft key 2, etc.
The soft keys are numbered from left to right and from top to bottom.
The arrow keys for the switching of the soft-key rows are logged.
Any newly called soft-key row starts with soft key 0 or V soft key 0.
All entries show the date and the local time.
Information on the start and end of NC programs is logged.
The machine manufacturer can use up to 8 additional OEM logs. --> If necessary, ask your machine
manufacturer if these OEM logs exist and whether they contain information relevant for service
technicians.
Note
The following messages are not shown in the log:
File system error x
Reason: In the case of a write or read error, all write activities on the hard disk are ceased as data
cannot be written reliably any more.
Relay external DC voltage missing
Reason: This message is always displayed on the monitor after the Power interrupted message
is confirmed. It is an information, not an error message. No entry is made to the log.
