Calculation example:
Components of the individual racks:
Central rack
Rack-CAN-Node Number: 1 (set on MIB module)
Bit rate: 250 kB
CAN termination at the MIB module, if CAN line to CAN bridge is <30 cm, otherwise provide a
120 Ohms terminating resistor at the CAN bridge, and switch off the termination at the MIB module
(Chapter 10.3).
Set on rack 2
Bitrate: 50 kB
Switch on the CAN-terminating resistor at MIB
Parameter Setting for CAN Bus A
Net 0 in the Central Rack
To reduce the data overflow at the CAN bus, the CAN bridge is provided with a filter which only
lets the data required pass through to NET 1.
Filter for NET 0 after NET 1:
