Revision Jan. 2009, 06EE, SW--PW V1.12/CTL V2.12 D-33
Program Example:
Ladder diagram: Command code: Operation:
LD X0 Load contact A of X0
ORI X2 Connect to contact B of X2 in
parallel
LDI X1 Load contact B of X1
OR X3 Connect to contact A of X3 in
parallel
ANB Connect circuit block in series
X0
X2
Y1
X1
X3
ANB
Block A Block B
OUT Y1 Drive Y1 coil
Mnemonic Function
ORB Parallel connection (Multiple circuits)
Operand None
Explanations:
To perform the “OR” calculation between the previous reserved logic results and contents of the
accumulative register.
Program Example:
Ladder diagram: Command code: Operation:
LD X0 Load contact A of X0
ANI X1 Connect to contact B of X1 in
series
LDI X2 Load contact B of X2
AND X3 Connect to contact A of X3 in
series
ORB Connect circuit block in parallel
X0
X2
Y1
X1
X3
ORB
Block A
Block B
OUT Y1 Drive Y1 coil
Mnemonic Function
MPS Store the current result of the internal PLC operations
