Profibus Interface (HG G-73351)
The Node-ID has to be selected via the serial monitor described in section 7.2 on
page 20. Using the GSD file
73351A0.GSD
(see section 12.4 on page 52 in the ap
-
pendix) two different configurations can be displayed, see below. The order of the
bytes within a 16 bit word can be altered using the Profibus menu, point
(see sec
-
tion 7.3.4 on page 26).
1. Reading only of 5 input bytes according to the following table:
The meaning of the status bits is determined as follows:
2. In addition to item 1 the frequencies of the two wires can be
adjusted
If values outside of the defined value range are transmitted they will be ignored. Fre
-
quency changes are carried out with the frequency switch time specified in the
Technical Data.
