7 Profibus Interface (HG 73351)
The Node-ID has to be selected via the serial monitor described in section 5.1 on page
12. Using the GSD file
73351A0.GSD
(see section D on page 45 in the appendix) 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 section 5.1.4 on
page 17).
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 Tech-
nical Data.
Value Format Range Description
Status unsigned 8 0..0xff Status bits according to Table 46 below
X1 signed 16 -255…..+255 -255 [mm]…..+255 [mm]
X2 signed 16 -255…..+255 -255 [mm]…..+255 [mm]
