The configuration in
the module is empty.
Download the appropriate configuration first.
Contact the factory if the error still exists.
Red light on All slaves are offline.
1. Detect if the PROFIBUS DP bus connection
is proper.
2. Detect if either end of the network is added
the terminal resistor.
Red light

At least one slave is
offline
1. Detect if the PROFIBUS DP bus connection
is proper.
2. Detect if both ends of the network have
connected the terminal resistors respectively.
12.7.2 Digital Display
The digital display displays the state of AH10PFBM-5A.

0~ 7D
When AH10PFBM-5A
works normally, the digital
display displays its node
address.

AH10PFBM-5A is in STOP
status.
Turn the RUN/STOP switch of PLC to RUN or
check if the hardware configuration in AH PLC is
consistent with that in the actual rack.
E2
AH10PFBM-5A detects that
one slave is offline.
1. Detect if the PROFIBUS DP bus connection is
proper.
2. Detect if both ends of the network have
connected the terminal resistors respectively.
E6
An error of some modules
connected to AHRTU-
PFBS-5A is detected by the
master.
Check the modules connected to AHRTU-PFBS-
5A.
F1
The configuration in the
master module is empty.
Download the appropriate configuration.
F2
PLC does not assign the
I/O mapping area to the
master
Assign the appropriate I/O mapping area to the
master via ISPSoft
F3
Master enters test mode
Re-power it.
F4 Master initializing error
Contact the factory if the error still exists after re-
powering 10PFBM.
F5
Timeout for the
communication between
chips inside master
Contact the factory if the error still exists after re-
downloading the appropriate configuration.
F6
Internal storage unit error
Contact the factory if the error still exists after re-
powering 10PFBM.
F7
Data exchange unit error
Contact the factory if the error still exists after re-
powering 10PFBM.
F8
the master serial number
detection error
Contact the factory if the error still exists after re-
powering 10PFBM.
FB
Timeout for the data
exchange with PLC
Contact the factory if the error still exists after re-
powering 10PFBM.
