ANB (AND Block)

Function

Connect ‘Block A’ and ‘Block B’ in series and take the result to the output.

ANB instruction is not a contact symbol but a connection symbol.

A maximum of 15 instructions (16 blocks) are available in case of writing the ANB continuously.

Example)

Steps	Instruction	Device
0	LD	X0000
1	OR	X0002
2	LD	X0001
3	OR	X0003
4	ANB
5	OUT	M0000
6	END
7	PEND

ORB (OR Block)

Function

-Connect ‘Block A’ and ‘Block B’ in parallel and take the result to the output.

-ORB instruction is used to connect the circuit block over two contacts in parallel. On the other hand, to connect the circuit block of one contact, use the OR and the ORI. ORB is not necessary in this case.

-ORB instruction is not a contact symbol but a connection symbol.

-A maximum of 15 instructions (16 blocks) are available in case of writing the ORB continuously.
