EVO
NETWORKS AND CONNECTIVITY
CONNECTION TO SUPERVISION SYSTEM
(ERGO SOLUTION)
Using serial port RS485 it is possible to connect EVO
controllers (up to 247) to a management software that uses
standard MODBUS RTU as a communication protocol, with
the following characteristics:
settable baudrate (defualt: 9600);
no parity
8 bits of data
1 bit of stops
Inside a supervision network, each EVO controller acts as a
SLAVE towards the centralised management system which
constitutes the network MASTER (figure 01).
Once the network has been wired, it is necessary to configure
each EVO controller. Press PRG to access the MENU and then
enter sub-menu "Networks and connections" (password =
20). Set the SETUP RS485 parameters as follows:
MST/SLV = "Slave from SPV"
Protocol = "Modbus"
Serial address = set a value between 1 and 255
Speed = set based on the requirements of the Master
leave the SETUP OC PARAMETERS UNCHANGED (MST/SLV
= none).
For details on how to wire the network, read
"RS485 NETWORK GUIDE LINES" available in
the download area of the Galletti website.
The following functions are recognised and managed by the
controller as SLAVE:
