Generally the projecting of a PROFIBUS-DP/-PA
1. The unit to be set up (TMT184) is connected to the PROFIBUS-PA
files in the configuration programme of the automation system. The values that are required
can be set up offline in the projecting software.
2. The operator programme of the automation system should now be set up. The in and output
data is controlled and fixed using the operator programme. Here the measured values can be
found in order to be able to analyse them. If the automation system does not support the IEEE-
754 floating decimal point format then an addition measured value conversion block must be
used. Dependent on the type of data management used by the automation system (Little-
Endian-Format or Big-Endian-Format), a change in the byte sequence may be needed (byte-
swapping).
3. Once the projecting has been completed this is transmitted to the automation system as a
binary file.
4. The system can be started once the projecting sequence has been completed. The automation
system connects to the projected units. Now the process relevant unit parameters can be set
up using a class 2 master, e.g. using Commuwin II.
