Mixed Network; Meanings Of Leds - Daikin FWECSA Manual De Instalacion Y Uso

SETUP parameters as follows:
• MST/SLV = set "Master" on the I/O board acting as
the MASTER of the network and "Slave" on all of the
SLAVEs in the network.
• Serial address = set a value between 2 and 34 on the
SLAVE controllers.
It is now possible to connect all of the I/O boards to the
network.
Once the board has been set as SLAVE, it can
no longer communicate with any random user
unit. Accordingly, if the settings are changed, it
will be necessary to RESET it in the following
manner: disconnect the board from the
network and, keeping it powered, place digital
input 10 in short circuit for 15 seconds (clamps
I10 and IC).
All of the hydronic units (i.e. both MASTER
and SLAVE) connected to the network must be
configured in the same way.

MIXED NETWORK

The SMALL network on CONVEYED WAVES can also be
connected to a supervision network (External Supervisor
System or SMALL solution) on RS485 through RS485 serial
port of the MASTER controller, thus obtaining what is known
as a MIXED NETWORK. Figure 04 illustrates the diagram
of a mixed network comprised of a SMALL network on
CONVEYED WAVES combined with a supervision network.
