  • Page 5: Introduction

    More intelligent and complex systems as well as the electrification of loads currently play a decisive role in the development of on-board electrical systems. The SCS200 is the right answer to these requirements. It is an intelligent power distribution system, allowing decentralised control and monitoring of loads via the CAN bus.

    The product is a slave module which is controlled by a superordinate control unit or ECU via the CAN bus. The SCS200 receives commands for switching the load outputs as CAN frames and, in the event of a change or upon request, provides diagnostic data and measuring values.

    Measuring accuracy cannot be guaranteed for the entire life span of the device. 6.3.3 Output status and troubleshooting The SCS200 provides feedback on the switching status of the channels and the status or error on the load itself in the form of CAN frames.

  • Page 15: Open Load

    6.3.3.1 Open load If a channel is switched on, but no or only very low load current flows, the SCS200 detects this condition as open load. A corresponding CAN message is sent off cyclically every 100 ms. The open load message is sent from the following current ratings: SCS200-SC…:...
  • Page 16 7 CAN communication The CAN communication of the SCS200 is based on the CAN 2.0B specification and supports the SAE J1939. The product can be integrated into a corresponding CAN system with other standard components. 7.1 Physical layer For a reliable communication, the CAN physical layer should be built up to the specifications of ISO 11898-2 or SAE J1939-1x.
  • Page 17 7.3.1 Address claiming The SCS200 is assigned an unambiguous node address. Upon delivery, this SCS200 ID is set to 0xA0 by default. The node address of the module can manually be changed per CAN message. Additionally, the SCS200 supports address claiming as per J1939-81 to independently claim an unambiguous source address on the bus.
  • Page 18 Adjustment of these values is via CAN messages. The superordinate control unit or ECU can directly send these CAN frames. The SCS200 can therefore be called a plug-and-play module. However, the SCS200 can also be addressed via the PC using standard CAN monitoring software.
