VEGACOM 557 Profibus FMS
Setup
Measured values from DISBUS
On DISBUS up to 15 bus participants can be connected, whereby each DISBUS participant
provides less than 16 measured values (between 4 and 7 measured values).
The bus addresses 1 … 15 must be configured on the VEGAMET instruments. Bus address 0
is not permitted, i.e. the measured values are between the second measured value block (for
VEGAMET with bus address 1) and measured value block 16 (VEGAMET with bus address
15). No measured values are saved on DISBUS in measured value block 0.
For reading in measured values via the DISBUS, the use of functional component FB211 is
recommended, if specific measured values of a DISBUS participant should be read in. With
functional component FB210, all 16 measured value blocks are read in. This is a special ad-
vantage if many bus participants are connected.

Measured values from LOGBUS
On LOGBUS, the image of the measured values is read in from the CPU card. The measured
values are read in starting from measured value block 1. For reading in the complete image
(256 measured values), the use of functional component FB210 is recommended. Individual
measured values can be read in with functional component FB212.
Diskette
The diskette contains the CP parameter settings and the components necessary to read in the
measured values described in this document. You should therefore read in the functional and
data components from the diskette and not enter them line per line in the STEP5 Editor.
The following files are saved on the diskette:
