This chapter explains the natures of errors which may occur during use of the
Q64RD/Q64RD-G and troubleshooting.
8.1 Error Code List
If an error occurs when data are written to or read from the programmable controller
CPU, the Q64RD/Q64RD-G writes the corresponding error code to the buffer memory
address 19 (Un\G19).
Error Code
(Decimal)
Description Remedy
10
The measurement range setting is other than 0 to 5.8 in the
intelligent function module switch setting.
indicates the channel number set incorrectly.
Make a correct setting in the intelligent function module
switch setting. (Refer to Section 4.5.)
111 A module error at start-up.
Switch power off, then on again. If the error recurs, the
module may have failed. Consult your local Mitsubishi service
center or representative.
112
Value set in the intelligent function module switch setting 5 is
other than 0. Set a correct value in the intelligent function module switch
setting. (Refer to Section 4.5.)
12
The offset/gain setting is other than 0 and 1 in the intelligent
function module switch setting.
indicates the channel number set incorrectly.
Make a correct setting in the intelligent function module
switch setting. (Refer to Section 4.5.)
13
The three-/four-wire type setting is other than 0 and 1 in the
intelligent function module switch setting.
indicates the channel number set incorrectly.
Make a correct setting in the intelligent function module
switch setting. (Refer to Section 4.5.)
161
1
The G(P).OGSTOR instruction was executed in the
offset/gain setting mode. Do not execute the G(P).OGSTOR instruction in the
offset/gain setting mode.
162
• The G(P).OGSTOR instruction was executed consecutively.
• At the time of offset/gain setting, a set value was written to
the E
2
PROM 26 or more times.
• Execute the G(P).OGSTOR instruction only once for one
module.
• At the time of offset/gain setting, write a set value only once
at one time.
163
• The G(P).OGSTOR instruction was executed for the model
that differs from the model for which the G(P).OGLOAD
instruction had been executed.
• The G(P).OGSTOR instruction had been executed before
the G(P).OGLOAD instruction was executed.
Execute the G(P).OGLOAD and G(P).OGSTOR instructions
for the same model.
20
The time averaging setting is outside the setting range.
indicates the channel number set incorrectly.
Set a correct value at the buffer memory address 1 to 4
(Un\G1 to 4). (Refer to Section 3.4.4).
30
The count averaging setting is outside the setting range.
indicates the channel number set incorrectly.
Set a correct value at the buffer memory address 1 to 4
(Un\G1 to 4). (Refer to Section 3.4.4).
31
The moving average setting is outside the setting range.
indicates the channel number set incorrectly.
Set a correct value at the buffer memory address 1 to 4
(Un\G1 to 4). (Refer to Section 3.4.5.)
32
The time constant setting is outside the setting range.
indicates the channel number set incorrectly.
Set a correct value at the buffer memory address 1 to 4
(Un\G1 to 4). (Refer to Section 3.4.5.)
40
In the offset/gain setting, or when the user setting is restored,
Gain value - Offset value 0.1 [C].
indicates the channel number set incorrectly.
Set a correct value in the buffer memory, or measure and
check the resistance of the RTD input terminals.
50
When the offset setting request (Y1, Y3, Y5, Y7) or gain
setting request (Y2, Y4, Y6, Y8) is turned on in the offset/gain
setting mode, the offset/gain setting of the intelligent function
module switch setting on that channel is not user-set.
indicates the channel number set incorrectly.
Make a correct setting in the intelligent function module
switch setting. (Refer to Section 4.5.)
51
When the offset setting request (Y1, Y3, Y5, Y7) or gain
setting request (Y2, Y4, Y6, Y8) is turned on in the offset/gain
setting mode, the "offset value" or "gain value" of that channel
is outside the measurement range.
indicates the channel number set incorrectly.
Check the measurement range and set the offset/gain value
within the range. (Refer to Section 3.1.1 (Q64RD) or 3.1.2
(Q64RD-G).)
52
The offset setting request and gain setting request were
turned on simultaneously in the offset/gain setting mode.
indicates the channel number set incorrectly.
Reexamine the sequence program so that they do not turn on
simultaneously.
1: This error code is written into G(P).OGSTOR instruction's completion status area (S) +1, not into the buffer memory address 19 (Un\G19).
