Description

The Beckhoff EL6021 serial interface enables the connection of devices with the RS422 or RS485 interface. These devices communicate with the automation device via the coupler. The active communication channel operates independently of the higher-level bus the system in full or half-duplex mode at up to 115.2 k.
