4.4.4 “eib1.txt” gateway file
The data points of the KNX protocol and their properties are defined in the
“eib1.txt” configuration file.
Table 4-6: Structure of the “eib1.txt” gateway file
No.
Description
Comment
1.
The KNX data points have the following
structure:
[<def> <group address>]
name = <name>
format = <format>
<def>:For the definition of data points, see
Table 3-1: Definition of the data point types
<group address>: Two- or three-digit
KNX group address.
Two-digit: <maj>/<min>
Three-digit: <maj>/<mid>/<ext>
<maj>: 0-31
<min>: 0-2047
<mid>: 0-7
<ext>: 0-255
<name>: Optional; you can specify plain text
for the data point.
<format>: Protocol-dependent properties of
the data point such as the data point for
interpreting the information stored at the
address.
If necessary, more parameters can be added
to the format, for example the poll rate (here:
P:10 for read value every 10 seconds):
format = <format> [F:<fact>]
[P:<poll>][U:<upd>] [I:<opt>]
[L:<loc>] [H:<prio>] [R:<addr>]
[D:<dly>]
For more driver-specific information such as
type, address, formats and other parameters,
please refer to the online documentation

[M failure]
name = EIB Failure
[M 1/1/1]
name = KNX-->S7 value
format = SINT16
[S 1/1/2]
name = S7-->KNX value
format = SINT16
[M 1/1/3]
name = KNX-->S7 switch
format = UINT1
[S 1/1/4]
name = S7-->KNX statusLED
format = UINT1
[X 1/1/5]
name = KNX-->S7 temperature
format = SFLOAT P:10
Note
For the driver to be provided with current values for all data points when starting
up the gateway, all data points defined in the driver must have the read flag set
on the ETS side.
