Appendix D How to Use PLC Function

Program Example: Ladder diagram:

X0 ANB X1

X2 X3

Block A Block B

	Command code:		Operation:
	LD	X0	Load contact A of X0
Y1
	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
	OUT	Y1	Drive Y1 coil

Mnemonic

ORB

Operand

Function

Parallel connection (Multiple circuits)

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:
	X0	X1 Block A		Y1	LD	X0	Load contact A of X0
					ANI	X1	Connect to contact B of X1 in
	X2	X3
							series
			ORB
					LDI	X2	Load contact B of X2
		Block B
					AND	X3	Connect to contact A of X3 in
							series
					ORB		Connect circuit block in parallel
					OUT	Y1	Drive Y1 coil

Mnemonic

MPS

Operand

Function

Store the current result of the internal PLC operations

None
