Revision March, 2008, Doc. Name: 2007PDD23000014 C-11
Program Example:
Ladder diagram: Instruction code: Operation:
LD X0 Loading in A contact of X0
ANDF X1 X1 falling-edge detection in series
connection
X1X0
Y1
OUT Y1 Drive Y1 coil
Mnemonic Functions
ORP
Rising-edge Parallel Connection
X0~X17 Y0~Y17 M0~M1279 S0~S127 T0~T127 C0~C254 D0~D599
Operand
9 9 9 9 9 9
