  • Page 5: Introduction And General Notes

    Introduction and General Notes Introduction kit is a ceramic sensor-based NH , measurement system that communicates and is configured via the CANopen protocol. Its primary application is for the analysis of combustion systems and their after-treatment. General Notes 1. All numbers are decimal unless preceded by the “0x” suffix which denotes a hexadecimal value: e.g.

  • Page 8: Connecting The Nh

    CAN bus at this baud rate is 100m. Each end of the CAN bus must have a terminating resistor of 121 Ohms. Application Notes 1. Configuration software (ECM Configuration Tool) for the module is located on the CD. This software allows the setup, configuration, monitoring, and recording of data using supported CAN adapters.

  • Page 12: Writing To The Nh

    Configuration of the NH CAN module is performed by writing to the Object Dictionary (OD) and by issuing ECM CANopen OS Commands (OS Command). Both of these actions are implemented using a Service Data Object Expedited Write (SDO Write). The format is as...

  • Page 14: Identifying The Nh

    Identifying the NH CAN Module Each NH CAN module can be uniquely identified by reading the following four parameters in the OD: Vendor ID (0x000001C6) located at OD address 0x1018, subindex 0x01 (4 byte integer/unsigned 32) Product Code (NH CAN = 0x00000012) located at OD address 0x1018 subindex 0x02 (4 byte integer/unsigned 32) iii) Revision Number located at OD address 0x1018, subindex 0x03...

  • Page 15: Commands To The Nh

    Commands to the NH CAN Module There are several commands that can be used with the NH CAN module. The commands are executed by performing an SDO Write to OD address 0x1023, subindex 0x01. A list of the commands can be found in Appendix B. ZEROing and SPANing All calibration information, including sensor constants and the user-performed span, is stored in a memory chip located in the connector of the NH...

  • Page 16: Canceling (Erasing) The Zero And Span

    0x01 0x0E If the ECM Error Code is from 0x10 to 0x3F inclusive, there is a problem with the module and/or the sensor memory. Therefore the SPAN will be ignored. A successful SPAN can be determined by reading locations 0x5000 and 0x5001 in the OD by performing an SDO Read. If the SPAN was successful those locations will read as 99999.0.
