8 .10 DSfG Protocol
The DSfG or Digitale Schnittstelle für Gasmessgeräte (Digital protocol for gas measurement
equipment) is a German protocol for Gas measurement. This elaborate, but dated protocol is
used to communicate between field devices and between a station and host computers. See
diagram below:

The blue box is a special communication board developed by KROHNE to handle the protocol
and data registration. The board is installed in the Summit and internally connected to a modi-
fied dual Ethernet board via a modbus link with the Summit as a slave. It comes as a kit con-
taining:
• DSfG communication board
• Dual Ethernet board with port 2 modified as an internal RS232
• A serial cable for internal connection between the two boards
• A software application with DSfG modbus and display configuration for DSfG
• A configuration program for the DSfG board
• A German DSfG manual describing the configuration
Import the modbus and display configuration to ensure proper communication between the
boards.
