9.2.6. Configuration of the valve terminal with extension terminal -
bitwise composition of the inputs and outputs
The settings of the desired configuration, i.e. setting of various identifiers, is generally done with the help of the
GSD file.
By using different identifiers the user can assign the input and output bytes in the process image at will. The iden-
tifiers are independent of the individual valve terminals.
The inputs / outputs are composed to one bitstream each in accordance with the parameterization from the
main terminal and the extension terminals. The bytes can be distributed in the process image on the basis of the
identifiers.
Example with inputs: (Z - Assignment; K - Identifier)
Bit 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

Manual configuration
If no GSD file is available the configuration must be performed manually. The following specifications apply. One
configuration telegram can contain one or several identifications, whereby the user can make the necessary allo-
cations at will. the identifications have the following structure:
Bit 7 Bit 6 Bit 5 - 4 Bit 3 - 0
Consistency
0 = byte/word
1 = total length
Bytes / Word
0 = bytes
1 = words (2 bytes)
Input / Output
00 = spec. identifier
format
01 = input
10 = output
11 = input/output
Length (amount of data)
0000 = 1 byte / word
...
0010 = 3 bytes / words
...
1111 = 16 bytes / words
