This chapter describes the STX functions of the CANopen® STX API.
CANopen® is an open standard for networking and communication in the
automation sector.
The CANopen® protocol has been further developed by the CiA e.V. (CAN in
Automation) and works on the physical layer with CAN Highspeed in
accordance with ISO 11898.
The CANopen® specifications can be obtained from the CiA e.V.
http://www.can-cia.org homepage. 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.
These STX functions are used in communication between the JC-120MC and
other CANopen® nodes.
