Explanation:
The ORI instruction is used in the parallel connection of B contact. The functions are to read out the
status of present designated parallel connection contacts and perform the “ORI” operation with the
logical operation result obtained. The final result will be store in the accumulative register.
Program Example:
Ladder diagram: Instruction code: Operation:
LD X0 Loading in contact A of X0
ORI X1 Connecting to contact B of X1 in parallel
X0
X1
Y1
OUT Y1 Driving Y1 coil
Mnemonic Functions
ANB
Series connection- loop blocks
Operand none
Explanation:
To perform the “AND” operation of the preserved logic results and content in the accumulative register.
