How PDOs are assigned to the PLC 

The following figure illustrates how PDOs are assigned to the PLC 
memory. 

 

Alternatively, it is possible to select assignment of the PDOs to 
flag areas or in data blocks. 

For larger CANopen

®

 projects, in particular, the use of data blocks 

is recommended because of the quantity of PDO data. 

 

However, be sure to adapt the parameters in FB 20 and FB 21 
accordingly. 

 
      CALL  FB    20 , DB20 
       Base   :=256 

       Dest   :=P#DB10.DBX 0.0 BYTE 400 

       STAT   :=MW20 
       Err    :=M22.6 
       RetVal :=MW24
