GENERAL DESCRIPTION
The device SS10580 allows to connect all the devices with Modbus RTU of a RS-485 serial line to the Ethernet with Modbus TCP protocol.
By the integrated web server it is possible to configure the option of Modbus TCP ( IP address, subnet mask, etc..) and Modbus RTU (baud rate, etc...)
The device realizes a full electrical isolation between the lines, introducing a valid protection against the effects of all ground loops eventually existing in
industrial applications.
The LEDs of signalling of Ethernet and the serial line communication activity and power supply allow a direct monitoring of the system functionality.
The connection is made by removable screw-terminals (inputs and power supply) and RJ45 plug (Ethernet).
The device is housed in a 2 module DIN rough self-extinguishing plastic box for mounting on EN-50022 standard DIN rail.

USER INSTRUCTIONS
The SS10580 can be connected directly to the SCADA, HMI o OPC server on the market that implement the Modbus TCP protocol. It is possible to connect at
the same time up to 8 clients; each command sent by a client over the Ethernet with Modbus TCP protocol is processed and re-transmitted over the RS-485
with Modbus RTU protocol to the slave devices connected. As soon as the response from the slave is received, it is processed and re-transmitted to client
which sent the query. By the integrated web server it is possible to configure the settings of network and serial line from any remote terminal.

 INSTALLATION INSTRUCTIONS CONNECTIONS
The SS10580 is suitable for fitting to DIN rails in the vertical position.
For optimum operation and long life follow these instructions: POWER SUPPLY
When the devices are installed side by side it may be necessary to DC AC
separate them by at least 5 mm. 1 + 1
When the devices are installed beside a power supply unit it is ~
2 2
necessary to separate them by at least 10 mm.
To connect the serial line RS485 it is suggested to use the cable Belden RS485 Point-to-Point
type 9842 suitable for RS485.
MASTER SLAVE
Make sure that sufficient air flow is provided for the device avoiding to place
raceways or other objects which could obstruct the ventilation slits. Moreover SHIELD SG SHIELD
it is suggested to avoid that devices are mounted above appliances D (-) - D (-)
generating heat; their ideal place should be in the lower part of the panel. D (+) + D (+)
Install the device in a place without vibrations.
Moreover it is suggested to avoid routing conductors near power signal
RS485 Multi-Point
cables (motors, induction ovens, inverters etc...) and to use shielded cable to
connect signals. MASTER SLAVE
CONFIGURATION BY WEB SERVER SHIELD SG SHIELD
To configure the device by web server: D (-) - D (-)
- Connect to the device via an internet browser D (+) + D (+)
- Select the language
- Click on “Settings” SLAVE
- Insert User Name (admin) and Password (admin) SHIELD
- Modify the parameters as desired D (-)
- Click on “Save Settings” and wait for that the reset occurs D (+)
FUNCTION BUTTON “RST”
To reload the default parameters of the device, keep pushed the button
“RST” on the front side of the instrument with device powered for at least 5
seconds. LIGHT SIGNALLING
The led PWR will become red and the reset of the device will occur.
The following parameters will be load: LED COLOUR STATE DESCRIPTION
PWR GREEN ON Device powered
Ethernet:
- IP Address : 192.168.1.100 OFF Device not powered
- Subnet Mask : 255.255.255.0 ERROR RED BLINK RS485 net error occurred
- Gateway Mask: 192.168.1.1 If button RST pushed – Reset of device occurred

OFF No error
RS485:
Stream of data over transmission line of RS-485
- Baud rate 38400 bps TX YELLOW BLINK ( the blinking frequency depends on Baud-rate)
- Parity: none
- Stop bit : 1 OFF No data over transmission line of RS-485
The modbus address is internally fixed to 255. Stream of data over receiving line of RS-485 ( the
RX YELLOW BLINK blinking frequency depends on Baud-rate)
TERMINATION RESISTANCE SELECTION FOR RS485 OFF No data over receiving line of RS-485
In the low part of the device it is possible to access to the dip-switch of
selection of termination resistance. If the cursor is on OFF position (to left) LNK GREEN BLINK Device connected to the Ethernet
the termination resistance won't be inserted. If the cursor is on ON position
(to right) the termination resistance of 120 ohm will be inserted across the OFF No data received from the Ethernet
lines of the RS485.
