Mnemonic Function Program steps
ORP Rising-edge parallel connection 1
Controllers
ES EX SS SA SX SC EH SV
X0 ~ X377 Y0 ~ Y377 M0 ~ M4095 S0 ~ S1023 T0 ~ T255 C0 ~ C255 D0 ~ D9999
Operand
9 9 9 9 9 9 -
Explanations:
The ORP instructions are used in the parallel connection of the contact’s rising-edge detection.
Program Example:
Ladder diagram: Instruction code: Operation:
LD X0 Loading in A contact of X0
ORP X1 X1 rising-edge detection in parallel connection

Operand
- 9 9 - - - -
Explanations:
When X0 goes from Off to On (rising-edge trigger), PLS instruction will be executed and S will send out pulses for
once of 1 scan time.
