Overview
To implement a CANopen bus, you have to define the physical context of the application in which the bus is integrated: rack, supply, processor, and modules. Then you have to ensure that the necessary software is implemented.
Implementation Principle
This table shows the different implementation phases:
Phase
Description
Mode
Configuration
Setting of configuration parameters.
Offline
Programming
Programming these specific functions:
  • Implicit bit objects or associated words via the device DDT
  • Explicit bit objects or associated words via read/write SDO
Offline or online
Transfer
Transferring the application to the PLC.
Online
Debugging and diagnostics
Debugging the application, controlling inputs/outputs, and accessing diagnostic messages with:
  • LED indicators
  • Device DDTs
  • DTM diagnosis
  • Embedded webpages
Online
Documentation
Printing the various information relating to the configuration of the CANopen master and devices.
Offline or online
NOTE:
  • For more information on modes (Offline or Online), refer to chapter Project management.
  • The above order is given for your information. Control Expert software enables you to use editors in the desired order of interactive manner.
NOTICE
DIAGNOSTIC DELAY
Use diagnosis system information and monitor the response time of the communication.
In case of disturbed communication, the response time can be 1 to 2s.
Failure to follow these instructions can result in equipment damage.
