MODBUS - CONVERTER CAN TO MODBUS VIA RS 485
Interfacing via RS 485 is performed using a converter for each unit.
The converter must be mounted on the electric board of the unit and connected, following the electric diagram attached
to the unit.
CONNECTIONS: refer to the electric diagram and to the SIGNAL/DATA LINES paragraph

UNIT NETWORK – MINI NETWORK – MASTER SLAVE
The CLIVET TALK Local Network system allows to connect up to 6 machines in a network which all serve the same
installation.
To interact with the network which controls the working of the system, it is necessary to have a CAN to CAN converter
code C5110692 for each machine.
Each single machine is equipped with the standard electronic devices: if necessary, it can function as an independent
unit.
