DeviceNet Application Layer

Robert Bosch GmbH developed the CAN bus as a communication system between electronic devices.
This very reliable hardware protocol works with a non-destructive bitwise arbitration.
Each messages on the 2-wire communication bus is like a train (44 bits) with up to 8 wagons (8 bytes).

The Application Layer software (the language) decides the number of wagons on the train and what's in them.
Although CD Systems developed their own Application Layer (AL) CDAL at first, nowadays we support
the general accepted protocols CANopen, DeviceNet and J1939.

DeviceNet is supported by:

Open DeviceNet Vendor Association ODVA.

More information about DeviceNet

CD Systems wrote a large description about DeviceNet.

We developed a number of DeviceNet devices like:

Cdios Modular I/O system

One DeviceNet CAN controller 6151 can control up to 16 I/O modules.
On this moment 16 different I/O modules are available to build almost any application.

CAN Core Module

This module can be the heart of your new DeviceNet development.

RS232 - DeviceNet interface

This device can be connected in a DeviceNet system to connect a RS232 device like a card reader or label printer.
