  • Page 5: Introduction

    May 2013) Layer setting services (LSS) and protocols This manual describes the functions supported by the HLB 1400 CANopen. A basic knowledge of CAN and CANopen is assumed. The exact function is described in the a.m. Draft Standards. Since both specifications are issued in English, the features described in this manual are identified using the English description from the specification and are shown in italics, for clarity.

    250 kbit/s and can be changed via the CANbus (see Object Dictionary Index 2002h). 4 CAN-Frames The HLB 1400 CANopen supports the 11-bit base frames with 11-bit identifier required in the specification. Extended frames with 29-bit identifier are not supported but are tolerated.

  • Page 7: Node Id

    Page 7 5 Node ID To operate the HLB 1400 CANopen in a CANopen network a unique Node ID have to be set within the network. The set Node ID is stored in a non-volatile memory, like the transmission rate, and can also be adjusted via the CAN bus (see Object Dictionary Index 2001h).

  • Page 8: Process Data Object (Pdo)

    Receive-PDOs With these, the actuating variables can be transmitted to an actuator or a controller. HLB 1400 does not provide any RPDOs. What is known as the PDO Mapping stipulates which data is now in a PDO. This PDO Mapping is stored in the Object Dictionary (see Object Dictionary, Index 1A00h and 1A01h).

  • Page 9: Synchronisation Object (Sync)

    CAN identifier used. The SYNC ID used is stored in the Object Dictionary. The HLB 1400 CANopen provides the functionality of a SYNC Consumer. If the PDO Transmission Type is set appropriately, a PDO is sent on receipt of a SYNC. The SYNC- ID is pre-set to 80h and can be changed in the Object Dictionary (see Object Dictionary, Index 1005h).

  • Page 10: Emergency Object (Emcy)

    Protocol Description HLB 1400 CANopen Page 10 6.4 Emergency Object (EMCY) EMCY objects are sent when an error occurs. EMCY objects contain an Emergency Error Code, the contents of an Error register as well as a Manufacturer specific Error Field. If a notified error is eliminated or disappears, this is also notified by a special EMCY object.

    PRE-OPERATIONAL The device does not send any PDOs, but can modify SDOs. The HLB 1400 CANopen can operate as a Heartbeat Producer. The ID of the Heartbeat is 700h + Node-ID. The time has been pre-set to 0 (not active) and can be modified (see Object Dictionary, Index 1017h).

  • Page 12: The Object Dictionary

    As has been mentioned several times, all the data are stored in the Object Dictionary. The entries supported by the HLB 1400 CANopen are listed in the following chapters. The index is always shown in hexadecimal notation, according to the specification, without the hexadecimal representation being shown extra.
  • Page 13 The HLB 1400 CANopen has implemented the analogue input part (Analogue Input Function Block) as 16 and 32 bit integer. These entries are in the area X100h to X1FFh.
