13.6 Multi-State Switch
The Multi-State Switch is a combination of Word
Lamp and Set Word. It displays a different state
depending on the value of the PLC monitor word
address. It also defines a touch area that when activated,
writes a specified data to the PLC word address, which
may be the same as the Read address or a different
address.
