C1 DSfG gateway
In summary, the
gas-net
DSfG gateway accomplishes the following tasks:
•
Cyclic or event-driven data polling at DSfG stations. Conversion of this data
into the host protocol, and its transmission to the host computer.
•
Cyclic or event-driven data polling at the host computer. Conversion of this
data into the DSfG protocol, and its transmission to DSfG stations.
•
Simulation of a gas quality entity towards the DSfG bus using gas quality
data provided by the host.
