Program Example:
Ladder diagram: Command code: Operation:
LD X0 Load contact A of X0
OR X1 Connect to contact A of
X1 in parallel
X0
X1
Y1
OUT Y1 Drive Y1 coil
Mnemonic Function
ORI Parallel connection- B contact
X0~X17 Y0~Y17 M0~M159 T0~15 C0~C7 D0~D29
Operand
9 9 9 9 9 --
Explanations:
The ORI command is used in the parallel connection of B contact. The function of the command is to
readout the status of present specific series connection contacts, and then to perform the “OR”
calculation with the logic calculation result before the contacts, thereafter, saving the result into the
accumulative register.
Program Example:
Ladder diagram: Command code: Operation:
LD X1 Load contact A of X0
ORI X1 Connect to contact B of
X1 in parallel
X0
X1
Y1
OUT Y1 Drive Y1 coil
Mnemonic Function
ANB Series connection (Multiple Circuits)
Operand None
Explanations:
To perform the “ANB” calculation between the previous reserved logic results and contents of the
accumulative register.
