USB data transfer module DFÜ-NG

The device DFÜ-NG represents a new generation of DFÜ units, which meets the basic functional requirements for the conversion from analogue to TCP/IP based measurement data retrieval from the gas pressure regulating and measuring stations (GDRM) and gas quality measuring stations (GBM) in German natural gas networks. The communication is based on the DSfG protocol. DSfG bus access via modem with control centre function Access to a DSfG bus via telephone/radio network or network, with DSfG control centre function Transmission of error messages to the central unit (list with error messages and devices configurable) Connection establishment to 4 panels possible Adjustable instance filter, which allows to limit the access of the control panels to certain devices Time synchronization of the bus participants with the time of telephone time service or time servers (SNTP or TIME Protocol) Direct (fast) data channel to a MRG 2200 or MRG 2203 Automatic baud rate detection on the DSfG bus Optional access to network-compatible devices via EADR routing via DSfG-B With an optional signature unit DSfG data records can be provided with a signature Parameterization program for PC Housing - Wall-mounted housing for top hat rail mounting Cassette housing for 19" subracks Communication modules - alternatively - GSM/GPRS module, - analogue modem, - Ethernet module, - ISDN module, - RS232 module Interfaces - RS232 for direct data channel, for parameter setting RS485 for DSfG bus USB for parameter setting optional Ethernet interface for EADR routing
