INSTALLATION AND USE MANUAL - REV 001A
2.0 - INSTALLATION
2.6 - Example of connection of a single instrument
2.7 - Connection of several instruments to the same CAN network
The instrument is equipped with a CAN bus data interface that allows several instruments to be connected with each
other for information exchange (CAN network).
A MASTER/SLAVE network structure is used, i.e. there is only one main chain counter (MASTER) and all the other chain
counters are secondary (SLAVE).
The network must have only one MASTER instrument.
The task of the MASTER chain counter is to align the length of the chain lowered and the operating parameters of all the
SLAVE chain counters.
The MASTER therefore is used as a reference for all the other SLAVE chain counters.
If a parameter in a menu for a SLAVE instrument is changed, the change is actually made to the MASTER instrument that
will automatically update all the SLAVE instruments (except for personal settings that contain particular functions and
parameters for every single chain counter not shared in network with the other chain counters).
If the MASTER chain counter should malfunction, one of the SLAVE chain counters can be set up as the MASTER.
Before using the chain counters on the CAN network, make sure the MASTER and SLAVE settings of all the chain counters
are correct and that the network works in a trouble-free manner.
