05
Connected PLC does not have the
H
same TLN as CP 541.
The CP 541 remains at RUN.
The CP 541 is at RUN and a pro-
grammer is connected.
The CP 541 remains at RUN.
Interference between CP 541 and
connected PLC which is cleared
without intervention.
The CP 541 remains at RUN.

Interference on SINEC L1 which is
H
H
cleared without intervention.
The CP 541 remains at RUN.
0B
The CP 541 has not received a DP
H
message from the connected PLC
within the monitoring time parameter-
ized in DPWD.
The CP 541 remains at RUN.
0C
The connected PLC has sent a broad-
H
cast, but BSAP is 0.
The CP 541 goes to STOP.

H
64 bytes has been received from SI-
NEC L2.
The CP 541 goes to STOP.
Circulating Buffer
Communications Processor CP 541
EWA 4NEB 812 6188-02
Meaning
The DB2 area for SINEC L1 message errors is established as a circulating
buffer. After the last and, therefore, also latest entry, FF
If the CP 541 detects a new error, it shifts the end marker (FF
and enters the new error message in the released field.
When the byte in DR17 has been written, the next byte is the one in DL13
again.
Diagnostics and Error Handling
Remedy
Specify the same TLN (node address/sta-
tion number) in both devices.
If you connect the programmer to the CP
541, you must set the mode switch to
STOP.
–
–
Increase the monitoring time specified in
DPWD.
Modify the user program in the PLC to al-
low more frequent sending to the DP mas-
ter.
You must not send a broadcast.
Or assign a value between 33 and 52 to
BSAP in frame COM.
The CP 541 can only transmit messages of
up to 64 bytes. Change the maximum
PLC-PLC message length in the sending
PLC.
