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.
