MODBUS COMMUNICATION
MODBUS COMMUNICATION IS POSSIBLE ONLY IF CI8021 CARD IS INSTALLED AND
ELECTRICALLY CONNECTED INSIDE THE CONTROL BOX.
Be sure the flat cable is correctly connected to
CI572P power board, on the dedicated black
connector.
Use the 3 upper left terminals of CI8021 card.
Using a shielded cable is recommended to avoid
communication perturbances, especially if a long
distance cable is used..
Connect the
cable’ shield on terminal GND.
The 2 other wires are dedicated to the
communication : Rx/Tx- and Rx/Tx +.
Terminals in the lower left part are
not used. They are dedicated to
factory use only.
