I am new to CodeSys and I am working on a project using a Wachendorff display communicating to several microcontrollers on a CAN network. I am writing the software for the controllers as well, so I don't want to use a formal protocol like CANOpen since I am controller the sending and receiviing. When I add a TXPDO or a RXPDO is there any reason I can't just map the 8 bytes of data any way I want and not set up a standard CANOpen message frame with the command byte, index and subindex, etc. If any one know where I can find a good sample program using CAN in CodeSys please let me know where i can find it. Thanks
