Code List
*1 To clear the error, modify the set value within the range and perform one of the following two operations:
• Turning on and off Error clear request flag (RYA)
• Turning on and off Initial data setting request flag (RY9)
*2 Turning on and off Error clear request flag (RYA) or Initial data setting request flag (RY9) does not clear this error. The
error is cleared only by the method described in the action column.

Moderate error
Input signal error
detection setting
out-of-range
A bit corresponding to any channel of Input
signal error detection setting (address: 0209H)
has been set to a value other than the setting
range.
 indicates the number of the channel where
an error has occurred.
Set one of the following values in the channel,
where an error has occurred, of Input signal error
detection setting (address: 0209H).
• Disable (0H)
• Disconnection detection (4H)

H Moderate error
Disconnection
detection setting
error
A channel where the input range is other than
the following is set to Disconnection detection
(4H) in Input signal error detection setting
(address: 0209H).
• 4 to 20mA
• 1 to 5V
 indicates the number of the channel where
an error has occurred.
• Set the input range of the channel that detects
disconnection within the range of 4 to 20mA or
1 to 5V.
• Set Input signal error detection setting (address:
0209H) of the corresponding channel to a value
other than Disconnection detection (4H).

Moderate error
Scaling setting out-
of-range
The values set in CH1 Scaling lower limit value
(address: 0221H) to CH4 Scaling upper limit
value (address: 0228H) are out of the range of
-32000 to 32000.
 indicates the number of the channel where
an error has occurred.
Adjust the value to fall within the range of -32000
to 32000 in CH1 Scaling lower limit value
(address: 0221H) to CH4 Scaling upper limit value
(address: 0228H).

*1 Moderate error
Scaling setting
upper/lower limit
inversion
CH1 Scaling lower limit value (address:
0221H) to CH4 Scaling upper limit value
(address: 0228H) have been set as follows:
Scaling lower limit value
≥ Scaling upper limit
value.
 indicates the number of the channel where
an error has occurred.
Adjust the settings of CH1 Scaling lower limit
value (address: 0221H) to CH4 Scaling upper limit
value (address: 0228H) as follows: Scaling lower
limit value < Scaling upper limit value.

*2
Moderate error
Excessive number
of conversion
enabled channels
The number of A/D conversion enabled
channels is too large to accommodate all the
channels in the synchronization period set in
the master station.
Take the following actions and then turn off and on
the module power supply, or perform remote
reset:
• Reduce the number of conversion enabled
channels.
• Change the synchronization period of the
master station to a longer period.
1F00H Major error
Extension module
connection error
The extension module is not connected
properly or the connected extension module
itself is not supported.
Check the contact state of the extension module
and whether the extension module is a
connectable module. If the same error occurs
again, the failure of the module is a possible
cause. Please consult your local Mitsubishi
representative.
1F30H Moderate error
Extension module
parameter error
The model name reflecting the parameter is
different from that of the connected extension
module.
Adjust Extension module identification code
(address: 0200H) to match the type and the
number of points with the connected extension
module.
1F50H Major error
Extension analog
module receive
data error
The data received from the extension analog
module is abnormal.
• Poor contact of the extension analog module or
the influence of noise is a possible cause.
• If the error persists even after contact check and
anti-noise action, the failure of the module is a
possible cause. Please consult your local
Mitsubishi representative.
1F60H Major error
Extension analog
module send data
error
The data sent to the extension analog module
is abnormal.
• Poor contact of the extension analog module or
the influence of noise is a possible cause.
• If the error persists even after contact check and
anti-noise action, the failure of the module is a
possible cause. Please consult your local
Mitsubishi representative.
