ARPO carry out an interconnection validation for each equipment according to the system engineering documents, as well as point to point communication tests between each equipment of the system.

ARPO verify also, the communication parameters and protocols between the equipments (generally MODBUS for serial communication and TCP/IP for communication by ETHERNET), realizes communication load tests (massive data communication), ARPO effects besides the checking of the system diagnostic screen for each one of the architecture active components and elements, realizing always the record of the above mentioned tests.
