7-3-8 Non Protocol
When the VS PLC’s communication port has been set to the application type of the “Non Protocol”, the PLC does not
execute any specied communication protocol. All communication procedures are operated by the PLC’s user
program. Then the RS instruction is used to receive and send out data in order to complete the communication
operation. This application type is often applied to communicate between PLC and peripheral, such as temperature
controllers, inverters and barcode readers.
