8.6 List of Warning Code
8.6 List of Warning Code
This clause shows the list of warning codes.
 of each warning code and warning name indicates the number of channel with a warning.
*1 While the value of either -2147483648 or 2147483647 is stored in CH1 Sampling count value (Un\G1056, Un\G1057),
CH1 Periodic pulse count, difference value (Un\G1058, Un\G1059), and CH1 Periodic pulse count value update check
(Un\G1062, Un\G1063), the count is continued.
*2 The operation is performed normally unless an error or a warning occurs.
● When another warning is detected during the warning occurrence, the information of the new warning are overwritten in
CH1 Latest warning code (Un\G1470) and in CH1 Latest warning detection time (Un\G1471 to Un\G1474).
● A warning code can be reset by CH1 Error reset command (Un\G1480). Yet unless the warning cause is removed, the
cause is detected again and the warning code is stored.

The values stored in CH1 Sampling count
value (Un\G1056, Un\G1057), CH1 Periodic
pulse count, difference value (Un\G1058,
Un\G1059), and CH1 Periodic pulse count
value update check (Un\G1062, Un\G1063)
are outside the range of -2147483648 to
2147483647.
