The D1 gas network device is a DSfG-RDT unit through which it is possible to remotely access the local DSfG * network in the gas metering and control station. A D1 gas network device is always used when it is not useful to implement remote access via the integrated RDT function of another gas network device for application-related reasons.
The DSfG-RDT unit can be controlled via telephone and modem or via TCP / IP interface and computer network, depending on the equipment of the device interface. It is possible to define up to 4 RDT stations with different access data.

  • Local DSfG interface according to DSfG class A
  • DSfG-RDT according to DSfG class B

* DSfG protocol is a digital data protocol, specially developed for communication between gas metering devices in gas metering and control stations.
