2.2.2
LEDs
4 LEDs are provided for function control
2.2.3
Turn-on Characteristics
On activation of power supply for the duration of the reset the positioning output is ac-
tive (approximately 500 ms) for the duration of the reset. All LEDS, except for the BUS-
LED, will be connected additionally for 500 ms each in order to test their function. After
approximately 2 s the device is ready for operation.
2.2.4
General Information
The code supplied by the transponder has a sequence of 24 bits, 16 bits are encoded.
The serial interface will only be applied for the monitor programme described in sec-
tion 4.2 on page 20. For this antenna the data as well as one status byte will be output
via the profibus. The programming of transponders can be implemented via the profi-
bus as well.
2.2.5
Profibus Interface
By means of the GSD files HG 7145A3 GSD (section 6 on page 25) it is possible to
project three different configurations.
LED
Signification
PWR
Indicates operating voltage applied
CD
Shines steadily, if a transponder is located in area I (see
Figure 2 on page 6)
DATA
-
Flickers, if a transponder approaches (range II in Figure
2 on page 6)
-
Shines continuously, if the transponder is read reliably
POS
Corresponds to the positioning output /
additional indicator function
-
Blinks once if an address >126 was adjusted
-
Blinks twice or three times, if internal profibus errors
occur
BUS
Shines on data exchange with profibus- master
