SINEC L1 Message Errors
The error codes for SINEC L1 message errors are stored in bytes in the diag-
nostics block (DB2) or the CP 541, in DW13 to DW17.
Meanings of the error codes and the remedies are given in Table 6-6.

01
H
The mode switch is at RUN and a pro-
grammer is connected to the L1 inter-
face or there is interference on SINEC
L1.
The CP 541 remains at RUN.
If you connect the programmer to the CP
541, you must set the mode switch to
STOP or
Remove the programmer.
02
H
The L1 slave sends a message with
destination address 0. However, you
have not configured a DP connection
or a non-safety-related connection
(S5-115F only).
The CP 541 goes to STOP.
You must not send an L1 master message.
You must configure a DP connection.
For S5-115F: You must configure a non-
safety-related connection.
03
H
L1 slave is sending to a node address
0. However, the CP 541 is config-
ured as a passive station.
The CP 541 goes to STOP.
You may only establish a DP connection.
You must assign a parameter to the CP 541
as an active station (STA = AKT).
04
H
The number of outgoing data from the
connected programmable controller to
the CP 541 is not the same as the pa-
rameter value of NWO.
The CP 541 goes to STOP.
Ensure that the data volume to the CP 541
agrees with the value of NWO.
You must always send a constant data vol-
ume with the DP connection.
Ensure that the parameter values in the
connected PLC, in the CP 541 and in the
DP master agree.
