Hold I/O data
After AH10PFBS-5A and PROFIBUS-DP master are
disconnected, retain the input and output data before
disconnection.
Clear I/O data
After AH10PFBS-5A and PROFIBUS-DP master are
disconnected, the output data is cleared to 0 and the
input data is unchanged.
13.8 LED Indicator and Troubleshooting
13.8.1 RUN LED and NET LED

RUN LED
RUN LED displays the status of the CPU module on the left of AH10PFBS-5A.
LED status
Indication
How to correct
Green light ON
PLC is in RUN
status.
--
OFF
The CPU module is
in STOP status.
Turn the RUN/STOP switch of the CPU module to
RUN.

NET LED
NET LED displays whether the communication between AH10PFBS-5A and PROFIBUS-DP
master is working normally.
LED status
Indication
How to correct
Green light ON
Normal
--
Red light ON
AH10PFBS-5A is
not connected to
the master.
1. Check if AH10PFBS-5A is connected to
PROFIBUS-DP bus.
2. Check if the communication cable between
AH10PFBS-5A and PROFIBUS-DP master is
in normal status.
3. Check if the actual address of AH10PFBS-5A
is consistent with that set in the master
configuration software.
4. Check if the GSD file used is correct.
13.8.2 Digital Displayer

Digital displayer displays the status of AH10PFBS-5A.
Code
Indication
How to correct
1~7D
When AH10PFBS-5A works
normally, the digital displayer
displays its node address.
--
80
The CPU module connected to
AH10PFBS-5A is in STOP status.
Turn the RUN/STOP switch of the CPU
module to RUN.
F0
The node address of AH10PFBS-
5A exceeds the valid range.
Set the node address of AH10PFBS-5A
between 1~125.
F1 Internal hardware error
If the error still exists after repowering
AH10PFBS-5A, replace it with a new
one.
F2 Parameter error
Check if the GSD file AH10PFBS-5A is
using is correct.
F3 Configuration error
Check if the GSD file AH10PFBS-5A is
using is correct.
