The Hipecs-CIO57 by Frenzel + Berg is a CANopen module with four current inputs for 0-mA-to-20-mA or 4-mA-to-20-mA signals. It is designed for extensions of PLC controller systems or similar applications. The I/O ports are galvanically isolated from the CAN Bus lines. The resolution of the A/D converter is 16 bit. All input channels are protected against short circuits and over current conditions. The CANopen interface complies with the CiA 301 application layer and the CiA 401 profile specification. All specified bit rates up to 1 Mbit/s are supported.
The operating temperature is from 0 °C to +55 °C, and a supply for external sensors is provided. The product measures 17,8 mm x 90 mm x 62 mm, and it comes in a plastic housing for mounting onto DIN carrier rails.
The module provides four TPDOs and four RPDOs. It features variable PDO mapping, and PDO linking. The following CANopen PDO scheduling modes are available: Synchronous, asynchronous, event-triggered, cyclic, acyclic, and remotely requested (Note: CiA does not recommend to use remotely requested PDOs). Event timer and inhibit timer for all transmit PDOs is provided. Heartbeat functionality is provided as well as the for new designs not more recommended node/life-guarding function.

Embedded Networking with CAN and CANopen
CAN (Controller Area Network) is a serial communication protocol that was originally developed for the automobile industry. CAN is far superior to conventional serial technologies such as RS232 in regards to functionality and reliability and yet CAN implementations are more cost effective. CANopen, a higher layer protocol based on CAN, provides the means to apply the ingenious CAN features to a variety of industrial-strength applications.
Many users, for example in the field of medical engineering, opted for CANopen because they have to meet particularly stringent safety requirements. Similar requirements had to be considered by manufacturers of other equipment with very high safety or reliability requirements (e.g. robots, lifts and transportation systems). Providing a detailed look at both CAN and CANopen, this book examines those technologies in the context of embedded networks.
There is an overview of general embedded networking and an introduction to the primary functionality provided by CANopen. Everything one needs to know to configure and operate a CANopen network using off-the-shelf components is described, along with details for those designers who want to build their own CANopen nodes. The wide variety of applications for CAN and CANopen is discussed, and instructions in developing embedded networks based on the protocol are included. In addition, references and examples using MicroCANopen, PCANopen Magic, and Vector’s high-end development tools are provided.
