• Check the timing again, in particular ensure that the settings in
SYSCLOCK_CYCLE_TIME and POSCTRL_CYCLE_DELAY are correct:
POSCTRL_CYCLE_DELAY must be larger for type 1. POSCTRL_CYCLE_DELAY must
be smaller for type 2.
• If alarm-free operation cannot be achieved with any POSCTRL_CYCLE_DELAY setting,
SYSCLOCK_CYCLE_TIME must be increased.
• If the error cannot be eliminated by this procedure, please make a note of the error text
and contact the control system manufacturer.
Clear alarm with the Delete key or NC START.
PROFIBUS DP: bus %3 SDB1000 error %1 for SDB source %2
%1 = Cause of the error
%2 = SDB1000 source
%3 = Number of the affected bus
Error in SDB1000 for PROFIBUS DP configuration.
Error cause:
• 01 = SDB1000 does not exist in SDB1000 source.
• 02 = SDB1000 in SDB1000 source too large.
• 03 = SDB1000 in SDB1000 source cannot be activated.
SDB1000 source:
• 00 = Default SDB (selected by MD 11240 = 0 if no user SDB1000 is loaded on the con-
trol system)
• 01 = Standard SDB1 (selected by MD 11240 = 1)
• 02 = Standard SDB2 (selected by MD 11240 = 2)
• .....
• 100 = SDB1000 stored in battery-backed memory (SRAM)
• 101 = User SDB1000 stored in file system
• 102 = SDB1000 reloaded in SRAM on startup
Reaction: PROFIBUS DP is inactive or operating in accordance with default SDB1000.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
• Check MD 11240.
• If SDB1000 source = 100: Reload user SDB1000 in passive file system /_N_IBN_DIR/
_N_SDB1000_BIN.
• If SDB1000 source = 101: Check backup batteries.
• If SDB1000 source = 102: Follow the procedure described for troubleshooting
alarm 380 001.
• If alarm 380 021 is also signaled, please follow the instructions provided for this alarm.
If the error cannot be eliminated by this procedure, please make a note of the error text
and contact the control system manufacturer.
Switch control OFF - ON.
Profibus-DP: default SDB1000 was loaded
No user-specific SDB1000 exists. The default SDB1000 was loaded during startup. With-
out process peripherals, the NC is reasy for a start-up. The alarm is triggered the first time
the NC is switched on or once if the SDB1000 stored in the supported RAM is lost.
- Alarm display.
