8.20 User-programmable CAN interface
CAN interface The user-programmable CAN interface lets you send and receive CAN mes-
sages. The CAN messages are completely processed in the application program.
Advantage of CAN This feature is not only apt for CANopen devices. It lets the user communicate
with third-party devices which are based on a CAN protocol.
Applications The user-programmable CAN interface can be used for the following applications:
■ Devices which are equipped with a CAN interface can be controlled via propri-
etary protocols
■ Controlling CANopen-capable devices
If your device supports the CANopen protocol, you should prefer to use the
CANopen STX API for [
}
108] communication.
Hardware
requirements The hardware required is a JC controller with CAN interface and/or JX2 system
bus.

8.21 CANopen STX API
The CANopen STX API provides a software platform that lets the user send and
receive CANopen messages via STX functions.
The CANopen
standard CANopen is an open standard for networking and communication in the automa-
tion sector. The CANopen protocol is being further developed by CiA e.V. (CAN
in Automation) and is based on the physical layer with CAN high-speed according
to ISO 11898.
Specifications The CANopen specifications can be obtained from the CiA e.V. homepage at
http://www.can-cia.org .
The key specification documents are:
■ CiA DS 301 - This document is also known as the communication profile and
describes the fundamental services and protocols used under CANopen.
■ CiA DS 302 - Framework for programmable devices (CANopen Manager,
SDO Manager)
■ CiA DR 303 - Information on cables and connectors
■ CiA DS 4xx - These documents describe the behavior of a number of device
classes in, what are known as, device profiles.
