GENERAL DESCRIPTION
The device SS8580 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 rough self-extinguishing plastic enclosure which, thanks to its thin profile of 22.5 mm only, allows a high density mounting on EN-
50022 standard DIN rail. .
USER INSTRUCTIONS
The SS8580 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
The device is suitable for fitting to DIN rails in the vertical position.
It is always a good thing to space the devices together 5mm. Make sure that sufficient air
air flow is provided for the device avoiding to place raceways or other objects which could
obstruct the ventilation slits. Moreover it is suggested to avoid that devices are mounted
above appliances generating heat. Install the device in a place without vibrations. It is
also suggested to avoid routing conductors near power signal cables and to use shielded
cables for connecting signals.
MODULE CON IGURATION
To configure the SS8000 series devices, it is necessary to enable the INIT mode. This
mode allows you to access the device with the following default parameters :
IP Address:192.168.1.174 (DHCP disabled), or IP provided by DHCP (if enabled)
Modbus Address: 245
To enter the INIT mode follow these steps:
- Turn off the device;
- Connect the INIT terminal to the -V terminal as shown in figure.
- Turn on the device and connect with an internet browser to the device using the default
parameters listed above and using the default login credentials:
Username: admin
Password: admin
To exit INIT mode follow these steps:
- Turn off the device;
- Remove the INIT connection;
- Turn on the device and connect with the new parameters.
RESET UNCTION- “P” BUTTON
If it is necessary to restore the default device parameters, with device powered and not in
INIT condition, push the front located “P” button for at least 5 seconds.
The green led PWR will switch-off, the yellow led STS will become orange and the reset
of the device will occur. When the reset procedure will be finished, both the leds will set
back to the default condition and the following parameters will be loaded :
Ethernet: Username: admin
- IP Address: 1 2.168.1.100 Password: admin
- Subnet Mask : 255.255.255.0
- Gateway Mask: 1 2.168.1.1 Modbus Address: 245
Baud Rate: 38400 bps
Timeout: 50 m
