Mnemonic Functions
ORB
Parallel connection- loop blocks
Operand None
Explanation:
To perform the “OR” operation of the preserved logic results and content in the accumulative register.
Program Example:
Ladder diagram: Instruction code: Operation:
LD X0 Loading in contact A of X0
ANI X1 Connecting to contact B of X1 in series
LDI X2 Loading in contact B of X2
AND X3 Connecting to contact A of X3 in series
ORB Connecting circuit block in parallel
X0
X2
Y1
X1
X3
ORB
Block A
Block B
OUT Y1 Driving Y1 coil
Mnemonic Functions
MPS
Store the current result of the internal EXIO operations
Operand None
Explanation:
To save the content in the accumulative register into the operational result (the pointer of operational
result will plus 1).
Mnemonic Functions
MRD
Read the current result of the internal EXIO operations
Operand None
Explanation:
To read the operational result and store it into the accumulative register (the pointer of operational
result stays intact).
Mnemonic Functions
MPP
Pop (recall and remove) the currently stored result
Operand None
