Development of HW Functions for CAN-Splitter Module
Eingestellt von FERCHAU Engineering GmbH
Gesuchte Skills: Engineering, Bussysteme
Projektbeschreibung
- The CAN-Splitter module consist only of HW components without any ?C function
- No software will be used to implement the functionality on the module
- A FPGA or similar integrated circuit will be used
- There is no mechanism implemented which directly indicates a trouble if there is fault on a CAN segment
- In this case the VdS compliant supervision mechanism of the devices directly (e.g. Keypad) or indirectly (e.g detector via LSN) connected ensures that the necessary troubles/alarms are indicated
- There is no data buffering within the module
- The physical signals on the different CAN segments are synchronous with respect to the timing requirements request by the CAN specification
- The CAN-Splitter needs to be in the panel enclosure as the CAN communication line is not redundant (VdS 2252-.2)
- The baud rate of the external CAN is configurable: 50k Bit/s, 80k Bit/s and 125k Bit/s
- Extended voltage tolerance (± 35V): transceivers in the CAN-Splitter have to provide the same voltage tolerance like already used CAN-transceivers (AMIS-42665)
- The existing CAN-connector concept includes a common ground line for all CAN devices of the system. If the CAN-Splitter solution provides only the two CAN communication lines the grounding concept of the system (incl. ground fault detection) has to be reviewed / updated
- The CAN-Splitter module behaves like a single physical line with redundancy function StandardsVdS2110 is testing this standard
- EN 60950-1 2012-09 Low Voltage Directive, Safety
- EN 61000-6-3 2012-11 Radiated Emission; substitute for EN 55022
- VdS (functional aspects)
- No specific requirements in addition closely related to a CAN-Splitter
- EN (functional aspects)
- No specific requirements in addition compared to VdS regulations
- CE and VdS requirements cover fully the EN requirements
