Its role is associated with the communication connection between the slave-side equipment and the control system architecture. Correct identification of the bus interface type is important when checking the installed hardware configuration and replacement requirements.\u003c\/p\u003e\n\u003cp\u003eThe module's standard non-explosion-protected construction should also be considered when verifying its intended installation environment.
