Table data used for comparison
Operation output setting (SET [1] or RESET [0]) [Up to 16 points]
1) When this instruction is executed, the redundant table in the table data is set as the redundant
comparison target.
2) When the current value of a high speed counter specified in becomes equivalent to the comparison
target table data, the operation output specified by the comparison target table data is reflected on
to +n-1.
If an output (Y) is specified in , the output processing is executed immediately without waiting for
the output refresh executed by END instruction.
When specifying an output (Y), make sure that the least significant digit of the device number is “0”.
Examples: Y000, Y010 and Y020
3) Immediately after the step 2), “1” is added to the current value of the table counter D8138.
4) The next table is set as the comparison target data.
5) The steps 2) and 3) are repeated until the current value of the table counter D8131 becomes "m".
When the current value becomes "m", the complete flag M8138 turns ON, and the execution returns to
the step 1). At this time, the table counter D8138 is reset to "0".
6) When the command contact is set to OFF, execution of the instruction is stopped and the table counter
D8138 is reset to “0”.

Operation output setting
= HA716
When the current value of the high speed counter
becomes equivalent to the comparison value, the
operation output setting pattern is output.
In the case of " =
Y000, n = K10"
