ESD GMBH CAN-CBM-DP CD 6124 PROFIBUS-DP to CAN Gateway Module

Overview

The ESD GMBH CAN-CBM-DP CD 6124 is a PROFIBUS-DP to CAN bus gateway module manufactured by esd electronics gmbh. The ESD GMBH CAN-CBM-DP CD 6124 works as a PROFIBUS-DP slave device to exchange cyclic process data between PROFIBUS-DP master systems and CAN bus field devices. It supports CAN 2.0A layer 2 communication and comes with matching GSD file for PLC and DCS configuration. The ESD GMBH CAN-CBM-DP CD 6124 is widely used as spare hardware for industrial automation bus conversion and legacy control cabinet maintenance.

Features

The ESD GMBH CAN-CBM-DP CD 6124 supports up to 300 bytes of input and output data exchange on PROFIBUS-DP side. It provides galvanic isolation between PROFIBUS-DP interface and CAN interface to reduce ground loop interference. The ESD GMBH CAN-CBM-DP CD 6124 includes LED diagnostic indicators for bus status, power and communication faults. It uses standard DIN rail mounting and supports easy parameter configuration via GSD file. The ESD GMBH CAN-CBM-DP CD 6124 matches the original pinout and mechanical dimension for direct drop-in replacement.

Specs

Device Type: PROFIBUS-DP / CAN gateway module Model: ESD GMBH CAN-CBM-DP CD 6124 Protocol: PROFIBUS-DP slave, CAN 2.0A (11-bit CAN-ID) Data Size: Max 300 bytes I/O data Power Supply: 24 VDC Mounting: 35mm DIN rail mount Protection Grade: IP20 Diagnosis: LED status indication Application: DCS, PLC, industrial bus conversion, CAN sensor and actuator networking

Principle

The ESD GMBH CAN-CBM-DP CD 6124 receives cyclic output data from the PROFIBUS-DP master and converts these messages into CAN frames to send to CAN bus nodes. It collects CAN bus messages from field sensors and actuators, packs the data into PROFIBUS-DP input telegrams and sends them back to the master controller. The module continuously monitors bus traffic and signal integrity. When bus timeout, short circuit or power failure occurs, the ESD GMBH CAN-CBM-DP CD 6124 stops data transmission and triggers status alarm.

Applications

The ESD GMBH CAN-CBM-DP CD 6124 is used for bus interconnection between Siemens PLC and CANopen or CAN layer 2 field devices. It serves communication conversion for machinery, mobile equipment and power plant automation systems. The ESD GMBH CAN-CBM-DP CD 6124 applies to spare stock and emergency repair of existing PROFIBUS-CAN bus networks. It also supports retrofit projects for upgrading old automation control systems.
