rofibus Menu (HG G-73351)
The specification of the Profibus telegrams is shown in chapter 9 on page 45. The
Profibus menu is made up as follows:
Figure 9
Screenshot: Profibus-Menu (HG G-73351)
In this menu the following keys have a specific function:
for choosing the node address in a range of 0 to 126
for inverting the order of the bytes of the variables X1, X2 and F2 within the
master- input and output data fields. Setting
(L)owbyte first
=
1
the low
byte of a 16 Bit word ist transmitted first.
Press
uit to return to the main menu.
If pre-defined, the content of the master input or the output bytes will be displayed
in this menu. The status of the profibus is output as well.
7.4 Switching to Different Environment Parameters
The interpreter can also be used in combination with tracking systems which have
another guide wire current or another reading height. Minor changes in the sur
-
rounding of the device (e.g. guide wire current between 35mA and 100mA at the
same reading height) are compensated by the dynamic range of the device.
The different guide wire currents, distances between the conductors and reading
heights are adapted to the antennas by changing the amplification factor. To change
these factors the monitor program has to be started, the displayed voltages Sx and
Dx have to get noticed.
The maximum of the sum voltage can be found above the conductor. By using the
corresponding potentiometer for the antenna, it has to be trimmed to approx. 12000
units. The maximum of the difference voltage can be found at a corresponding dis
-
tance collateral from the conductor. By using the corresponding potentiometer for
the antenna it has to be trimmed to 6000 units.
7.5 Firmware-Update
The processor inside the interpreter can be programmed via a Flashloader using the
serial interface. Therefor a serial connection to a PC has to be established.
