  5. Horner Configurator • CANOpen configurator is tool integrated with Cscape used for configuration of CANOpen protocol in Horner OCS. • Supports Configuration of the CANOpen Network (Master Node) or individual slave node. • Launching Configurator from the Cscape. Program -> Network Configuration will launch CANOpen configurator.

  6. Configuration of Simple Network (Master) CANOpen Network ID : 1- 127 CANOpen Network Baud Rate Additional Master Settings CANOpen Network status register

  7. Setting Node ID, Baud Rate and Other master node settings CANOpen Network ID : Unique ID provided to each node, no two nodes can have same ID. CANOpen Baud Rate: User can select any of the 4 supported baud rate, for the given network each slave node has to be set to same baud as that of Master node. Different nodes at different baud rate cannot communicate with each other. Additional Master Settings: Perform NMT Start Node all: Checking this option Master will send a single start command over the CANOpen Network to start all the slaves. Do Not Enter My self Operational Automatically: Checking this option will ask for trigger bit to start Master node, which will intern start all other slave nodes in the network. Do not send NMT start command: Checking this option master node does not send any start command over the network, each slave must be configured for self start. On error Control event of mandatory slave, NMT reset all nodes: Checking this option master node resets CANOpen communication (it self and all nodes on the network) in case of error in any of the mandatory slave. On error Control event of mandatory slave NMT stop command: Checking this option master node sends stop command over the network to stop the CANOpen communication in case of error in any of the mandatory slave.

  8. EDS Files CANOpen EDS (Electronic Data Sheet) file serves as template for different configurations for one device type. EDS file describes - Communication functionality and objects as defined in /CiA301/ and Application Frameworks. - Device specific objects as defined in the device profiles Loading EDS file : Right click on node -> Load From EDS, will open EDS Loader. Load specific EDS file using EDS loader. Note: All EDS files for different devices are stored under Cscape-> EDS folder

  9. Device Type and Status Information Displays the device type information loaded from EDS file

  10. Special Function Object Configuration Sync Object configuration field Time Stamp Object configuration field Emergency Object field

  11. Special Function Object Configuration (Continued) • Sync Protocol Parameter Configuration:The Synchronization Object is broadcasted periodically by the SYNC producer. This SYNC provides the basic network clock • SYNC COB-ID: Default COB-ID for Sync message is 0x80, user can change as per his requirement. • Generate SYNC Message: Selecting this option will produce SYNC messages i.e. Node will act as SYNC producer. Available only in QX and NX series. In the given network only one node can be SYNC producer and other nodes will act as SYNC consumer. • Communication Cycle Period : Enter required SYNC object cycle period in microseconds.0 if not used • Synchronous Window Length : Enter the length of the time window for synchronous PDOs in microseconds. It is 0 if not used.

  12. Special Function Object Configuration (Continued) • Time Stamp Configuration:Currently not supported in the firmware. • Emergency Protocol Parameter Configuration: Emergency objects are triggered by the occurrence of a device internal error situation and are transmitted from an emergency producer on the device. Master node will consume Emergency Messages generated form several nodes. • EMCY COB-ID: Default COB-ID for EMCY message is 0x80 + NODE ID, user can change as per his requirement. • Disable EMCY : Selecting this option will disable generation of Emergency messages. • Inhibit Time EMCY : Enter required inhibit time for the EMCY message.

  13. Error Control Protocol Configuration Node Guard Protocol configuration field Heartbeat consumer configuration field Heartbeat Producer configuration field • Horner OCS supports both Node Guarding and Heart beat type of error control protocol. • User can select any one of the Error control protocol for the given network.

  14. Error Control Protocol Configuration (Continued) Configuring Node Guarding Protocol: • Select ‘Use Node Guard Protocol Error Control’ . • Configure Guard time and Life time factor for individual slave. Master node does not require configuration of Guard time and Life time factor. Configuring Heart Beat Protocol: • Select ‘Use Heart Beat Protocol Error Control’ . • Configure Producer Heartbeat Time if given node is Heartbeat producer. • Configure Consumer Heartbeat time for individual node if node is Heartbeat consumer. Note: • Master node by default will act as heartbeat consumer. • Given Node can be both producer and consumer. • The consumer time configured must be greater than or equal to producer time.

  15. SDO Configuration Service Data Objects: • Service data objects are designed to access entries in device object dictionary . • By default SDOs are configured automatically. • Each node will support single Server SDO and additional server SDOs can be configured. • Client SDOs are supported only in Master.

  16. PDO Configuration The real-time data transfer is performed by means of "Process Data Objects (PDO)". • PDO Communication Parameter Configuration: Configured PDO list Click to add new PDO Entry Click to Delete selected entry Click to take default information for a given entry from EDS. Click to apply changes made in configuration PDO configuration field

  17. PDO Configuration (Continued) Receive PDO Communication Parameter Configuration (RPDO ): • PDO COB-ID Entry • PDO COB-ID: Configure required 11 bit COB-ID in this field, click on ‘Set default’ to read from EDS file • Disable PDO: Select this option to disable configured PDO. • Use 29 Bit ID: Select this if COB-ID length is 29 bit. • PDO Transmission Type : Select type of PDO receive method (Depends upon actual transmission type)

  18. PDO Configuration (Continued) Transmit PDO Communication Parameter Configuration (TPDO ): • PDO COB-ID Entry • PDO COB-ID: Configure required 11 bit COB-ID in this field, click on ‘Set default’ to read from EDS file • Disable PDO: Select this option to disable configured PDO. • Use 29 Bit ID: Select this if COB-ID length is 29 bit. • Allow RTR: Select this option if PDO needs to be transmitted on Remote request.

  19. PDO Configuration (Continued) Transmit PDO Communication Parameter Configuration (TPDO ): • PDO Transmission Type : Select type of PDO transmission method, select On change, On trigger or On RTR type. Trigger type requires trigger bit to be configured • Asynchronous On change configuration. • Asynchronous On trigger configuration. • Asynchronous On RTR configuration. • Synchronous On change configuration. • Synchronous On Sync count configuration. • Synchronous On RTR configuration.

  20. PDO Configuration (Continued) Transmit PDO Communication Parameter Configuration (TPDO ): • PDO Timing Parameter : • Event Time : Configure event time for asynchronous messages in ms. 0 if not used • Inhibit Time : Configure inhibit time for asynchronous messages in ms. 0 if not used

  21. PDO Configuration (Continued) PDO Mapping Parameter Configuration: Applicable to RPDO and TPDO Configured PDO Mapping list List box displaying mapped object for given PDO To view and edit mapped object Characteristics Click to delete selected mapped objects Click to view map able objects Supported by device (Information read from EDS) Click to apply changed characteristics of selected object. Click to add new object entry in the list.

  22. PDO Configuration (Continued) PDO Mapping Parameter Configuration: Applicable to RPDO and TPDO Mapping Objects can be selected from EDS as shown here Click Select required Object and click OK • Note: • Single PDO can take up to 4 -16 bit objects, or 8 – 8 bit Objects or 2-32 Objects and vice versa • User can directly map OCS register to PDOs, conversion of OCS native register index to CANOpen index and vice versa is taken care by configurator.

  23. Slave Configuration • Right click on Master node tree to add additional slaves (as shown) • Load Device specific EDS file (as shown) • Configure required node-ID. • Mandatory Slave: Select this option if slave node is Mandatory. • On Error, Start “Boot Sequence” : Select this option if given node has to be rebooted on error.

  24. Slave Configuration (Continued) Model XLe/t will only support simple master where in it cannot reconfigure the slaves. • Do not send NMT reset if Operational: If selected Master will not send reset command on boot up if node is in operational state. • Check Node type, Profile, Vendor ID, Product Code, Revision No., Serial No.: Selecting this option master will check these information on network Boot-up. If any of information doesn’t match then master will set Error.

  25. Slave Configuration (Continued) Configure Special function Objects and Error Control Object for given slave

  26. Slave Configuration (Continued) NX and QX series support CANOpen manger functionality where in Master can reconfigure slaves in the network as per configuration stored in Master on boot up.
