coded error output
Function Blocks - FM 458-1 DP
Edition 12.2004
Error statuses which occur for the appropriate block are output in a
coded form at outputs YF of the SIMOLINK blocks. Only the last error
event is displayed.
Value Significance
2 TAD input is incorrectly connected
3 SLB module not inserted or hardware defective
4 SLB module is already being used by another central block @SL
5 Memory problem
6 Central block @SL not configured
7 No SIMOLINK block available
8 Memory register was not set-up
9 Software does not support the hardware combination
10 Block must be configured in an interrupt task
11 Block must be configured in a cyclic task
12 Block must be configured in a cyclic task with TX=T0
13 Equivalent sampling time must be equal to T0
14 Interrupt source for the alarm task is incorrect
15 Blocks must be configured in the same sampling time
16 Operating mode is (still) not supported
17 Node address at input ASL is too high
18 No send- and receive blocks available
Note: However, if send and receive blocks are configured, then the
fault messages at these blocks should be carefully observed!
19 Maximum number of SIMOLINK telegrams (max. 1021 net
telegrams) exceeded → increase SIMOLINK cycle time or configure
fewer SIMOLINK blocks
20 Slave address too high
21 Channel number too high
22 Slave attempts to write to the incorrect address
23 Cross-data transfer is only possible in one direction per slave
(sending or receiving)
30 Physical data transfer along the SIMOLINK ring is faulted
→ increase the send power at one of the partial segments, or the
fiber-optic cable medium or connector is defective
31 CRC error (check sum error)
32 Timeout error in the SIMOLINK ring
33 Only for MOD=0: signaled SIMOLINK cycle time (in the special
telegram from the SL master) does not correspond to the configured
equivalent sampling time
SIMOLINK drive coupling
