14.8.2 Digital Display

The digital display displays the status of AHRTU-PFBS-5A.
Code Indication How to deal with
1~ 7D
When AHRTU-PFBS-5A
works normally, the digital
display displays its node
address.
--
80
AHRTU-PFBS-5A is in
STOP status.
Turn the RUN/STOP switch of the master PLC to
RUN.
F0
The node address of
AHRTU-PFBS-5A exceeds
the valid range.
Set the node address of AHRTU-PFBS-5A
between 1～125.
F1
1. AHRTU-PFBS-5A has
not been connected to
the PFOFIBUS-DP
network.
2. The PFOFIBUS-DP
master has not
configured
AHRTU-PFBS-5A
1. Check if AHRTU-PFBS-5A has been
configured to the PROFIBUS DP master
configuration software.
2. Check if the communication cable between the
PROFIBUS DP master and AHRTU-PFBS-5A
is normal.
3. Check if the PROFIBUS DP master works
normally.
4. Check if the two terminal nodes at both ends of
the PROFIBUS DP network have been added
with the terminal resistors.
F2 Parameter error
Check if the GSD file AHRTU-PFBS-5A is using is
correct.
F3
1. An configuration error
2. No configuration of I/O
modules for
AHRTU-PFBS-5A
1. Check if the GSD file AHRTU-PFBS-5A is
using is correct.
2. Check if the I/O modules for
AHRTU-PFBS-5A are configured in the
Profibus DP configuration software
F4
An error in initialization of
AHRTU-PFBS-5A
Contact the factory if the error still exists after
AHRTU-PFBS-5A is repowered.
F5
An error in internal memory
units
Contact the factory if the error still exists after
AHRTU-PFBS-5A is repowered.
F6
AHRTU-PFBS-5A loses the
communication with the
master.
Check if the communication cable between the
PROFIBUS DP master and AHRTU-PFBS-5A is
normal.
E4
Inconsistency between the
actual I/O modules
connected to the rack and
those configured via the
software
1. Check if the actual I/O modules connected to
the rack are consistent.with those configured
via the software.
2. Check if any I/O module connected to the rack
is damaged or does not exist.
E5
1. An error in an extension
rack
2. The actually connected
rack is not consistent
with that configured in
the software.
1. Check if the extension rack communication
cable is connected properly.
2. Check if the extension rack is normal.
3.
Check if the actually connected rack is
consistent with that configured in the software.
E6
An error alarmed from the
modules connected to
AHRTU-PFBS-5A
1. Check if there is any error in the module
hardware.
2. Check if the power supply works normally.
3. Check if the input signal exceeds the hardware
range.
