4.4.5 “pnetd1.txt” gateway file
The data points of the PROFINET protocol and their properties are defined in the
“pnetd1.txt” configuration file.
Table 4-7: Structure of the “pnetd1.txt” gateway file
No.
Description
Comment
1.
The addresses of the PROFINET data points
have the following structure:
[<def> <type> <byte>.<bit>]
name = <name>
format = <format>
<def>: For the definition of data points, see
Table 3-1: Definition of the data point types
<type>:
inbyte: Byte value that can be read by the
controller
inbit: Single bit that can be read by the
controller
outbyte: Byte value that can be written by
the controller
outbit: Single bit that can be written by the
controller
<byte>: 0..339 ( nth byte in the input/output
register)
<bit>: 0..7 (single bit within the nth byte)
<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 a poll rate (P:x):
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
