Error code
(decimal)
The offset value is equal to or larger than the gain value.
1
40 *
indicates the channel number causing the error.
More than one channel was set at the same time during
1
500*
offset/gain settings.
The specified digital value is outside the range.
2
60 *
indicates the channel number where the error occurred.
The warning output upper/lower limit value setting is out-
1 side the range -32000 to 32000.
61 *
indicates the channel number incorrectly set.
The warning output lower limit value is equal to or greater
1 than the warning output upper limit value.
62 *
indicates the channel number incorrectly set.
The analog adjustment output in the offset/gain setting
1
700*
mode is outside the specified value range.
The increase/decrease digital limit value setting is outside
1 the range 0 to 64000.
80 *
indicates the channel number incorrectly set.
The scaling upper/lower limit value is set outside the range
1 of –32000 to 32000.
90 *
indicates the channel number set incorrectly.
The scaling lower limit value is equal to or greater than the
1 scaling upper limit value.
91 *
indicates the channel number set incorrectly.
Table8.2 Error code list (2/2)
Error description
(1) When two or more errors occur, the latest error code is stored.
(2) The error described with 1 can be cleared by turning ON the error clear
request (YF).
(3) If the error marked 2 occurs continuously, it is added to the error history of
GX Developer in each conversion cycle.
(4) If an error marked 3 occurs, D/A conversions on all channels will stop.
Therefore, after correcting the offset/gain setting, make the initial setting
again.
(5) Error code 161 marked 4 is not stored in the Error code (Un\G19). It is writ-
ten to the Completion status area, (S) + 1, of the G(P).OGSTOR instruction.
Processing
Reset so that the offset value is smaller than the gain
value.
Set the correct value in offset/ gain setting mode(Un\G22,
Un\G23).
Set a value that is within the range.
Correct the contents of the warning output upper limit
value/lower limit value (Un\G86 to 97) to within the range -
32000 to 32000.
Make setting so that the warning output upper limit value is
greater than the warning output lower limit value.
Change the contents of offset/gain adjustment value speci-
fication (Un\G24) so that it is within the range from –3000
to 3000.
Correct the contents of the increase/decrease digital limit
values (Un\G70 to Un\G81) to within the range 0 to 64000.
Correct the scaling upper/lower limit value (Un\G54 to
Un\G65) within the range of –32000 to 32000.
Set CH scaling upper/lower limit value (Un\G54 to
Un\G65) so that the scaling upper limit value is greater
than the scaling lower limit value.
