The meanings of error codes in AH10PFBS-5A shown in the system log of PLC are listed in the 
following table. 
16#A0F0 
AH10PFBS-5A exceeds the 
valid range. 
Set the node address of AH10PFBS-5A between 
1~125. 
16#A4F1  Internal hardware error 
If the error still exists after repowering AH10PFBS-
5A, replace it with a new one. 
16#A4F2  Parameter error 
Check if the GSD file AH10PFBS-5A is using is 
correct. 
16#A4F3  Configuration error 
Check if the GSD file AH10PFBS-5A is using is 
correct. 
16#A4F4  GPIO detection error 
If the error still exists after repowering AH10PFBS-
5A, replace it with a new one. 
16#A4F5 
mode of factory test. 
Repower AH10PFBS-5A after setting its node 
address between 1~125. 
16#A4F6 
been connected to the 
PROFIBUS-DP network. 
2.  PROFIBUS-DP master 
has not configured 
AH10PFBS-5A slave or 
the configured node 
address of AH10PFBS-
5A is inconsistent with 
that of the actually 
connected one.   
1.  Check if the communication cable between 
AH10PFBS-5A and PROFIBUS-DP master is 
in normal status. 
2.  Ensure that AH10PFBS-5A slave has been 
configured to PROFIBUS-DP master and the 
configured node address of AH10PFBS-5A is 
consistent with that of the actually connected 
one. 
3.  Check if PROFIBUS-DP master works 
normally.
