12.6 DHSZ / High Speed Counter Zone Compare
Comparison table
1) When this instruction is executed, the top table
in the data table is set as the comparison
target data.
2) When the current value of the high speed
counter C251 is equivalent to the comparison
target data table, the output (Y) number
specified in the comparison data table is set or
reset.
This output processing is directly executed without regard to completion of output refresh by END
instruction.
3) "1" is added to the current value of the table counter D8130.
4) The comparison target data table is transferred to the next table.
5) The step 2) and 3) are repeated until the current value of the table counter D8130 becomes "4".
When the current value becomes "4", the program execution returns to the step 1), and the table counter
D8130 is reset to "0".
At this time, the complete flag M8131 turns ON.
6) When the command contact is set to OFF, execution of the instruction is stopped and the table counter
D8130 is reset to "0".
