Explanation
When an error in some I/O
module connected to
AHRTU-PFBS-5A occurs,
AHRTU-PFBS-5A stops the data
exchange between other I/O
modules and the master and
meanwhile reports the E4 error.
When an error in some I/O
module connected to
AHRTU-PFBS-5A occurs, other
I/O modules continue running and
AHRTU-PFBS-5A reports the E4
fault.
When the communication
between AHRTU-PFBS-5A and
the master is disrupted,
AHRTU-PFBS-5A stops all I/O
modules running and reports the
F6 error.
When the communication
between AHRTU-PFBS-5A and
the master is disrupted,
AHRTU-PFBS-5A continues
running and reports the F6 error.
Little Endian: valid only for digital

modules.

Take the 32-point output module
for example.
If AH10PFBM-5A is the master
and D6000 & D6001 correspond
to the 32-point output module, in
D6000, bit0~bit7 correspond to
Y0.0~Y0.7 and bit8~bit15 to
Y0.8~Y0.15; in D6001, bit0~bit7
correspond to Y1.0~Y1.7 and
bit8~bit15 to Y1.8~Y1.15.
If a Siemens PLC is used as the
master and PQD256（containing
PQB256, PQB257, PQB258 and
PQB259） corresponds to the
32-point output module, PQB256
corresponds to Y0.8~Y0.15,
PQB257 to Y00.~Y0.7, PQB258
to Y1.8~Y1.17, PQB259 to
Y1.0~Y1.7.
All digital input and output
modules follow the corresponding
relationships above.
The option is recommended to
select when AH10PFBM-5A is the
master.
