base conditions to be applied into consideration.
The gas quality data can be parameterized as constant values.
Besides, the FC1 can use gas quality data that are actually measured on-
site by a GQ measurement device (e.g. a gas chromatograph):
The FC1 supports the connection of some specific GQ measure-

ment devices to a serial interface (COM Port) or LAN interface. The
used protocol standard is Modbus, Modbus IP, or a manufacturer-
dependent protocol, respectively. The Basic System is responsible
for the protocol interfacing and makes the gas quality data available
