Serial communication protocol
The Modu_Control card manages (towards the BMS/VMF supervisor) both
the Register values (whole/analogue) and the Coil values (digital). The
commands that can be used to read/write these values are:
MODBUS commands
DIGITAL VALUES LIST (COIL):
To be able to write the COIL parameters on
the Modu_Control card, you must enable the
supervision commands by setting the parameter
parameter (N) = 1 of the installer menu
(password=30) of the panel on the machine.

The Modu_control card allows an inter-
face with a centralised system via a spe-
cial serial expansion card based on the
RS485 electric standard and using the
Modbus RTU standard protocol.
The Modu_Control card is always the
slave of the communication.
To enable communication from a supervi-
sion system to the Moducontrol card, you
must set the following parameters:
• Parametro J - Ad1 (Indirizzo modbus
del supervisore);
• Parametro L - Bd1 (Baudrate supervisore);
It is also necessary to ensure compliance
with the following characteristics:
• Stop bits: 2;
• Parity: NONE;
