Figures within this chapter contain CPAD2 screenshots only. Activate CPAD2/CPAD3 modules Click on "Settings" > "Hardware Setup" > "CAN" Select the CAN device you are using Set the CAN Port you use for the CPAD to acknowledge Set the CAN Port to CPAD2/CPAD3 in the special devices section.

All modules listed in the "used modules" are automatically sorted by the module ID. By default the module ID is the serial number, but it could be changed by clicking on it. You can change the data format, the arbitration type and the baud rate in the configuration mode.

  • Page 62: Max. Cable Length & Modules Per Can Bus

    Max. cable length & modules per CAN bus Maximum Cable Length and Modules per CAN Bus There are several parameters that have to be considered when building a CAN bus network with CPAD modules. Baud rate A higher baud rate allows a higher sample rate or using more CPADs. On the other hand, it reduces the maximum cable length.

  • Page 63: Power Supply Considerations

    Power supply considerations Power Supply considerations Depending on the power supply only a certain number of modules can be connected. If longer cables are used this number is reduced because of the cable resistance. Typical configurations: 12 V, 200 mA (DSUB-9 from ORION board) 5 m bus length max.
