7 Parameter of the gas
Manual ERZ 2000-NG · EN07 · 2019, May 13th

Possible characteristics of the utility values are a substitute value (of the converter), a
living value (of the GC) or as a hold value (of the GC). Fields
IH03
to
IH29
show the
assignable gas composition data. In order to use them for the conversion, "RMG bus"
operating mode must be parameterized for the appropriate measurement inputs. The
assignment of the computer to a stream (1...4) takes place in
IH43 Stream selection
(The PGC of RMG enables up to 4 measuring points). The setting "without reference"
means no stream assignment. The setting "Start with error" in coordinate
IH44 Iniital.
RMGB GC
after NETWORK ON generates an alarm during the calibration phase. It
disappears as soon as valid gas composition data is available.
Fields
IH50
to
IH77
show the original gas composition data originating directly from
the PGC. They are used in combination with the stream selection and adopted to the
values
IH03
to
IH29
if applicable. The original data can also be forwarded to other
computers via a COM interface with the operating mode "RMG Bus output".
Note
With display of the gas composition data, slight deviations from the original
values of the PGC can arise due to the format definitions.
Overview
x
The RMG bus transmits the gas analysis data of a PGC (e.g. GC 9000, GC 9300)
to one or multiple computers (e.g. ERZ2000, ERZ2000-NG).
x
The PGC master sends a write request telegram as a broadcast every 30 sec-
onds to all computer slaves on the bus.
x
The data field of the telegram contains gas analysis data, the stream number and
status information.
x
The bus operates as RS-485. The wiring takes place in the same manner as for
the DSfG bus.
x
COM 4 is provided as an interface for the ERZ2000-NG. The plug assignment of
COM 4 is described in
chapter 3 Electrical connections.
COM 4 is configured as RS-485
x
COM 4 is implemented on the COM3/COM4 board.
x
It is configured with coding plugs or jumpers as RS-485 or RS-232.
x
The positioning variants of the plug elements are printed on the circuit boards.
x
The bus termination takes place with the DIL switches (see
Figure 103: DIL
switches of COM 3 and COM 4
and
Figure 228: Coding plugs and bridges of COM
3 and COM 4
).
