Error name Description and cause
A value out of the range is set for a bit
corresponding to any channel of Input signal
error detection setting (address: 0109H).
 indicates the number of the channel where
an error has occurred.
Disconnection detection (4H) has been set in
Input signal error detection setting (address:
0109H), and the input range has been set to a
value other than the following values.
• 4 to 20mA
• 1 to 5V
 indicates the number of the channel where
an error has occurred.
The values set in CH1 Scaling lower limit value
(address: 0121H) to CH4 Scaling upper limit
value (address: 0128H) are outside the range
of -32000 to 32000.
 indicates the number of the channel where
an error has occurred.
The scaling lower limit value has been set
equal to or greater than the scaling upper limit
value in CH1 Scaling lower limit value
(address: 0121H) to CH4 Scaling upper limit
value (address: 0128H).
 indicates the number of the channel where
an error has occurred.
The value set in Mode switch (address:
0000H) has been changed.
The value set in Cyclic data update watch time
(address: 0007H) is outside the range of 0 to
20.
The setting of the station number switch has
been changed while the module power is on.
The clock data acquired from the CPU module
is invalid.
An invalid data that implies an altered setting
of the communication LSI has been received.
An invalid data that implies an altered setting
of the communication LSI has been received.
In synchronous communication mode,
RWwF/RWrF has not been set in the
RWw/RWr setting.
Synchronous communication with the master
station has failed for a certain period of time.
CHAPTER 11 TROUBLESHOOTING
Action
Set the value in the channel, where an error has
occurred in Input signal error detection setting
(address: 0109H), to either of the following:
• Disable (0H)
• Disconnection detection (4H)
• 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:
0109H) of the corresponding channel to a value
other than Disconnection detection (4H).
Set a value within the range of -32000 to 32000 in
CH1 Scaling lower limit value (address: 0121H) to
CH4 Scaling upper limit value (address: 0128H).
Correct the settings of CH1 Scaling lower limit
value (address: 0121H) to CH4 Scaling upper limit
value (address: 0128H) so that the scaling lower
limit value is smaller than the scaling upper limit
value.
Turn off and on the module power supply to
operate the module as specified in Mode switch
(address: 0000H).
Set a value within the range of 0 to 20 in Cyclic
data update watch time (address: 0007H).
While the module power is on, set the switch
again to the station number that has been set
before.
The influence of noise or the hardware failure is a
possible cause. If the same error occurs again
even after measures have been taken against
noise, please consult your local Mitsubishi
representative.
Take measures against noise and reset the
module. If the same error occurs again, the
hardware failure of the module is a possible
cause. Please consult your local Mitsubishi
representative.
Take measures against noise and reset the
module. If the same error occurs again, the
hardware failure of the module is a possible
cause. Please consult your local Mitsubishi
representative.
Set RWwF/RWrF to be assigned with the
RWw/RWr setting and then turn off and on the
power supply, or perform remote reset.
Take the following actions and then turn off and on
the power supply, or perform remote reset:
• Change the synchronization period of the
master station to a longer period. Alternatively,
reduce the number of slave stations being
active in synchronous communication mode.
• Taking measures against noise on the
transmission path
