MODBUS is an application layer packet transport protocol, which is a request / response protocol that provides functional code provision for the client / server communication between the devices. The test scheme describes the MODBUS communication test in asynchronous serial mode such as EIA-422, EIA/TIA-485-A, EIA/TIA-232-E.
