Communications interface

Specifications: VIEW - DOWNLOAD

The interface manages the RS485 communications bus, between the CPUs and the communications server (DORLET DASS).

DORLET's RS485 bus is fully supervised and can be configured as a serial or ring bus. As a ring bus, bus violations can be detected (bus cut off) without the equipment (still connected) being affected in the communication. The interface allows up to 50 CPUs to be controlled for each RS485 bus.

interface - architecture

There is a special protocol to avoid disrupting CPUs that are not communicating with the server. The interface systematically pools the bus CPUs, supervising their status.

The interface can be supplied with RS232 communications for direct connection to the server or with TCP-IP communications, connecting it to the ETHERNET network.
