CAN Bus Termination
Flatpack2 systems are shipped from factory with the
CAN bus already terminated with 120 resistors.
To ensure a correct bus communication and avoid data
reflection, you must always terminate the CAN bus with
two 120 resistors, one at each end of the line (60 bus
impedance). The figure shows a Flatpack2 system
communicating via the CAN bus.
CAN Bus Addressing
All rectifiers and control units (controllers and CAN nodes) connected to the Eltek Valere’s CAN bus must
have a unique address or ID number. The power system’s master controller assigns automatically the
rectifiers’ addresses (software assignment). The master controller registers the rectifiers’ ID numbers – or
CAN bus address (01, 02 ...) – together with their Serial Numbers.
The power system’s control units make use of DIP switches for configuring their unique CAN bus ID
number (hardware assignment). The only exception is the Compack and Smartpack2 Master controllers,
which have factory assigned specific ID numbers <1>and <11> (not changeable).
In the control system’s CAN bus, you can address a maximum of 14 CAN nodes of each type, 8 Smartpack
and Smartpack2 Basic controllers and 8 Smartnode units. See table below:
For DIP switch configuration, refer to actual control unit’s guide or to WebPower Help.
The figure shows a Flatpack2 DC power system with Smartpack2-based control system and 4 CAN nodes
to implement additional digital inputs, relay outputs or similar functionality.
