Anybus Communicator protocol converter for EtherCat connects automation devices via their RS-232/422/485 interfaces to EtherCat. Typical applications include barcode readers, RFID scanners, weigh scales, frequency inverters and motor starters. A compact device for standard DIN rail mounting, the communicator operates as an EtherCat slave and contains all protocol functions including the CANopen based application layer for process data (PDO) and parameter data (SDO) communication functions. The network connection is made via two RJ45 connectors and supports 100 Mbit Ethernet transmission.
