Description
Parameter setting using GX
Configurator-MB was applied to the
programmable controller CPU while the
R
MODBUS device assignment
parameter starting method specified by
the intelligent function module switch
was set to "Start with the default
parameters".
The CPU response monitoring timer
value in the buffer memory (address:
000D ) is incorrect.
H
The device code value specified as a
MODBUS device assignment
parameter is incorrect.
The head MODBUS device number
+ assigned points in the MODBUS
device assignment parameter exceeds
the maximum value (65535) allowed for
the MODBUS device.
MODBUS device ranges set with
the MODBUS device assignment
parameters are overlapped.
The assigned range of the QJ71MB91
buffer memory set with the
MODBUS device assignment
parameter exceeds the range of the
user free area.
The head device number + assigned
points in the MODBUS device
assignment parameter exceeds the
maximum value (65535) allowed for the
CPU device.
The specification of the error status
read device is incorrect.
The access target specification value is
other than 0 and 1 when the
QJ71MB91 is mounted on the
MELSECNET/H remote I/O station.
The access target (when mounted to
MELSECNET/H remote I/O station)
(address: 000E ) was set when the
H
QJ71MB91 is not mounted on the
MELSECNET/H remote I/O station.
Data were written to the system area
(use prohibited) in the buffer memory.
Corrective Action
• When using the default parameter
setting, delete the QJ71MB91
parameters entered to the
programmable controller CPU.
• When starting the QJ71MB91 with
parameters set from GX
Configurator-MB or the sequence
program, turn ON the MODBUS
device assignment parameter
starting method of the intelligent
function module switch.
Review the CPU response monitoring
timer value.
Review the device code value.
Review the head MODBUS device
number and the number of assigned
points.
Review the head MODBUS device
number and the number of assigned
points.
Review the head device number and
the number of assigned points.
Review the head device number and
the number of assigned points.
Review the setting of the error status
read device.
Set the access target specification
value to 0 or 1 when the QJ71MB91 is
mounted on the MELSECNET/H
remote I/O station.
Review the access target station or the
specified access target value (when
mounted to MELSECNET/H remote I/O
station).
Check whether or not writing to the
system area (use prohibited) in the
buffer memory was executed by the
sequence program.
