DAT3580-MBTC Ethernet Gateway Modbus TCP Modbus RTU.
GENERAL DESCRIPTION
The gateway DAT3580-MBTCP allows to connect the Modbus RTU devices of a RS-485 network to the Ethernet network through the Modbus TCP protocol.
By means of the Telnet interface it is possible to configure all the Modbus TCP side options (IP address, subnet mask, etc..) and the Modbus RTU side options (baud rate, etc...).
The device guarantees a full isolation between lines, allowing the use even in heavy environmental conditions. DAT3000 series devices are designed to be easily mounted on DIN rail, optimizing the space encumbrance. The thermal dissipation allows the devices to be mounted side by side, allowing a relevant reduction of required. The connections are made by means of removable screw terminals, to simiplify the handling of the devices.
LED signalling of Ethernet activity and data rx-tx on the serial line allows a direct monitoring of the system funcionality. The connection is made by removable screw-terminals (supply and RS-485) and RJ45 plug (Ethernet).
DAT3580-MBTCP is in compliance with the 89/336/EEC directive on the electromagnetic compatibility.
The device is housed in a rough self-extinguishing plastic container which, thanks to its thin profile of 22.5 mm only, allows a high density mounting on EN- 50022 standard DIN rail.
USER INSTRUCTIONS
DAT3580-MBTCP can be connected directly to the SCADA, HMI or OPC-server software, that are implementing the Modbus TCP protocol. It is possible to connect up to 8 clients at the same time; each request sent by a client with the Modbus TCP protocol on the Ethernet newtork will be retransmitted with the Modbus RTU protocol to the slave devices connected on the RS-485 network. Just the response will be received by the device, it will be retransmitted to the client who sent the request. By means of Telnet interface, it is possible to set all the configuration options from any remote terminal.
TECHNICAL SPECIFICATIONS
INSTALLATION INSTRUCTIONS
The DAT 3580-MBTCP device is suitable for fitting to DIN rails in the vertical position.
For optimum operation and long life follow these instructions:
When the devices are installed side by side it may be necessary to separate them by at least 5 mm in the following case:
- If panel temperature exceeds 45°C and high power supply value( > 27Vdc).
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 it is suggested to avoid that devices are mounted above appliances
generating heat; their ideal place should be in the lower part of the panel.
Install the device in a place without vibrations.
Moreover it is suggested to avoid routing conductors near power signal cables (motors, induction ovens, inverters, etc...) and to use shielded cable for connecting signals.
