• Details on the system error can be read via the RS232 interface. Start the
ID 40/KONF program after connecting the diagnostics cable to the COM port of a
computer (see also ID 40/KONF manual).
Pressing the ENTER key displays information on the fatal system error as well as
the ID 40/SLK emergency shell:
Assertion failed: ..
ID 40/SLK Emergency Shell
Commands: m - dump RAM pagewise, M - dump all RAM, l - logdump
B - burn log to flash, E - erase logs in flash, R - reboot slk
Pressing the “L” key outputs the system's syslog buffer. This makes it possible for
Service to trace the source of the error.
Save the log dump initiated by pressing the “L” key as a file and send it to Service
along with the text starting with “Assertion ..” or “Exception ..”.
The system can be restarted by pressing “R” (reboot). This corresponds to a cold
start, so the PLC application may also have to be reinitialized and restarted.
It is no longer possible to operate the ID 40 website after a fatal system error.
Possible causes of errors:
1. Defective equipment
2. Pretransmit function being on constantly without being deactivated occasionally.
This can result in memory overflow in the SLK
3. Access to invalid SLK address ranges with older SLK software versions (3.00 or
lower), see Chapter 5 “SLK storage”
What to do when a fatal system error occurs
1. Save at least one line of the running text from the ID 40/KONF using a log file,
a screen shot (Alt+Print Screen) or writing it down. Send it to Bosch Rexroth
Service so they can analyze the error
2. Reset the SLK by turning it off, then on again. If the error persists and causes 2
and 3 have been ruled out, contact Bosch Rexroth Service
System behavior with older SLK software versions (3.00 or lower)
• A ticker is visible on the display showing information on the error
• The syslog may still be readable with ID 40/KONF. If possible, send the content to
Bosch Rexroth Service
