will be 0, indicating that ELC performs the comparison based on the group 0 data.
6. When the group 0 data in the table has been compared, the ELC will first execute at the
frequency set in group 0 data (D2, D3) and copy the data to D1152 and D1153, determining if
the comparison reaches the target number of groups. If the comparison reaches the target,
M1153 will be On; if the comparison has not reached the final group, the content in D1151 will
add 1 and continue the comprison for the next group.
7. M1153 is the flag for the completion of one execution of the table. It can be turned Off by the
user. Or when the next comparion cycle takes place and the group 0 data has been compared,
the ELC will automatically reset the flag.
8. If you wish to use this mode with the PLSY instruction, preset the value in D1152.
9. If you wish to stop the execution at the last row, set the value in the last row to K0.
10. When X10 turns Off, the execution of the instruction will be interrupted and the content in
D1151 will be reset to 0.
11. When in this mode, the frequency of the input pulses cannot exceed 50KHz or the neighboring
two groups of comparative values cannot differ by 1; otherwise there will not be enough time
for the ELC to react and result in errors.
