Explanation
1. PED/APED/OPED correspond to LDP/ANDP/ORP. The only difference between PED/APED/OPED and
LDP/ANDP/ORP is that you must specify the bit device S
PED/APED/OPED is executed. Do not use the device S
result appears.
2. APED connects the rising-edge detection of the contact in series.
3. OPED connects the rising-edge detection of the contact in parallel.
4. The system must scan PED/APED/OPED to get the state of the device. Changes to the device state are not
detected until PED/APED/OPED is scanned the next time
5. You can use PED/APED/OPED only in function blocks.
6. The state of the operation result is automatically output after the instruction is executed. You do not need to use an
input device for this.
