－
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” calculations with the logic calculation result before the
contacts, thereafter, saving the result into the accumulative register.
Command code: Operation:
LD X0
Load contact A of X0
ORI X1
Connect to contact B of
X1 in parallel
OUT Y1
Drive Y1 coil

Mnemonic Function
ANB Series connection (Multiple Circuits)
Operand None
To perform the “ANB” calculation between the previous reserved logic results and
contents of the accumulative register.
Command code: Operation:
LD X0 Load contact A of X0
ORI X2
Connect to contact B of
X2 in parallel
