Explanations:

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” calculation with the logic calculation result before the contacts, thereafter, saving the result into the accumulative register.

Program Example:
	Ladder diagram:					Command code:		Operation:
			X0	Y1		LD	X1	Load contact A of X0
						ORI	X1	Connect to contact B of
			X1
								X1 in parallel
						OUT	Y1	Drive Y1 coil
	Mnemonic						Function
		ANB			Series connection (Multiple Circuits)
	Operand						None

Explanations:

To perform the “ANB” calculation between the previous reserved logic results and contents of the accumulative register.
