Loading data handling blocks 

The CAN CD contains the data handling blocks for the CAN 300 
PRO in the form of a Step 7 example project (ZIP file or directory). 
You will find the project as “C3PRO_CANopen

®

_V1x.ZIP” and 

newer in the “STEP7\CAN 300 PRO” directory. Open this project 
to use the blocks. 

 

Copy the blocks into the project you created with your hardware 
configuration and transfer all block to the PLC.
