  Connecting the Kinco HMI to a CANopen network

  
  

  For the connection, you need a Kinco HMI with CANopen slave interface. This interface is designed in addition to the serial interfaces and a possible Ethernet interface.

  Driver configuration for CANopen in the Kinco HMIware

  
  To configure your Kinco HMI as a CANopen device, carry out the following steps in the Kinco HMIware:t. Double-click to open the configuration of the HMI and select Fieldbus.
  

  1. Create a new project in Kinco DTools or open an existing project
  2. Drag an HMI that supports CANopen into your project
  3. Double-click to open the configuration of the HMI and select Fieldbus Setting
  4. Add the HMI under "Add" and configure the protocol as CANopen and the node ID of the HMI
  5. Close all open windows with Ok
  6. Create screens and objects that are linked to variables in the PLC (more on this under Addressing)
  7. Compile the project and transfer it to the HMI via download

  Kinco HMI elements

  
  Kinco HMIware provides a wide range of elements for visualizing and changing PLC data. These include, for example, switches, lamps, input fields and much more.
  
  For operation as a CANopen slave, these elements are linked to internal variables of the HMI. The CANopen masters can then access these variables themselves as PDOs and read or write them.

  Address overview of the PDO standard mapping

  
  There is a standard mapping of the internal variables to the PDO for the Kinco HMI. This looks as follows:
  
  

  Address rangeKinco	addressCANopen	PDO
  Receive PDOs
  Register 16 Bit	LW 8000-8003	PDO 0x1400 (Id: $NodeID+0x200)
  	LW 8004-8007	PDO 0x1401 (Id: $NodeID+0x300)
  	LW 8008-8011	PDO 0x1402 (Id: $NodeID+0x400)
  	LW 8012-8015	PDO 0x1403 (Id: $NodeID+0x500)
  Send PDOs
  Register 16 Bit	LW 8016-8019	PDO 0x1800 (Id: $NodeID+0x180)
  	LW 8020-8023	PDO 0x1801 (Id: $NodeID+0x280)
  	LW 8024-8027	PDO 0x1802 (Id: $NodeID+0x380)
  	LW 8028-8031	PDO 0x1803 (Id: $NodeID+0x480)

  
  

  
  
  

  Custom PDO mappings with the PDO manager

  
  In addition to the standard mapping, it is also possible to create your own mapping via the Kinco PDO Manager and transfer it to the HMI.
  

  You can find the PDO Manager in the start menu in the Kinco "Tools" directory. Open the supplied EDS file. This can be found in the Kinco installation folder in the "fieldbus" directory. Alternatively, you can also upload the EDS configuration from the Kinco HMI. Then adapt the PDO configuration to your requirements.

  
  
  

  After the change, transfer the new ESDS configuration to your Kinco HMI via download.

  
  
  

  Important: In order for the adapted mapping to be applied, you must set the value for "Predefined PDO Mapping Parameters" to "No" in the fieldbus settings in the configuration of your HMI.
