In the case of "
Y000, n = K10"
1) When this instruction is executed, the data table is set as the comparison target.
2) When the current value of the high speed counter, specified in
comparison value in the data table, the corresponding operation output specified in the data table is
output to
D
If an output (Y) is specified in
the output refresh executed by the 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 step 2), "1" is added to the current table counter value D8138.
4) The next comparison point is set as the comparison target data.
5) Steps 2) and 3) are repeated until the current value of the table counter D8138 becomes "m".
When the current value becomes "m", the instruction execution complete flag M8138 turns ON, and the
execution returns to 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".
