*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 Mode switch setting change (error code: 0920H) is not cleared even if five seconds has passed since the error occurred.
During the error, the operation continues in the mode previous to the change of Mode switch (address: 0000H).
To clear the error staying in the previous mode, set Mode switch (address: 0000H) back to the original value and then
turn on and off Initial data setting request flag (RY9).
*3 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.
For two or more errors, only the latest error code is stored in Latest error code (RWr0) or Latest warning code (RWr1).
The errors that have occurred in the past can be checked in the error history of the engineering tool.
For the error history, refer to the following:
• Checking by executing a command of the slave station (

0E20H
*3
Moderate error
Synchronization
period setting error
The synchronization period set in the master
station is not supported by the A/D converter
module.
Adjust the synchronization period of the master
station and then turn off and on the power supply
of the A/D converter module, or perform remote
reset.
0E30H
*3
Moderate error
Synchronous
communication
error 2
Synchronous communication with the master
station has failed for a certain period of time.
Take measures against noise on the transmission
path and then turn off and on the module power
supply, or perform remote reset.
0E40H
*3
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 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 whether the extension modules are in
contact with each other 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.
1F20H Moderate error
External power
supply OFF error
The external power supply monitoring function
is enabled; however, the external power supply
of the extension output module is in an off
state.
• Check the state of the external power supply of
the extension output module.
• If an error occurs at the system startup or the
system stop, correct the timing to enable the
external power supply monitoring function.
1F30H Moderate error
Extension module
parameter error
The mode 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.
1F40H Moderate error
Input response time
setting error In the low 3 bits of Input response setting
(address: 0010H), 000b or 001b has been set. Set a value other than 000b and 001b to the low 3
bits of Input response setting (address: 0010H).
D529H Major error
Communication
error 1
An error has occurred in the communication.
• The malfunction due to noise or other factors is
a possible cause. Check the distance of the
wire and cables and the grounding condition of
the individual devices. and then take measures
against noise.
• Execute a unit test for the module. If the same
error occurs again, the hardware failure of the
module is a possible cause. Please consult your
local Mitsubishi representative.
