The data format in detail:
Notice
!
The AMS 200 makes a new
3
2-bit long data set available every 1.6 ms. Depending on the
number of configured participants and the quantity of data to be transferred by the partici-
pants, the baud rate of 500 kbit/s can result in the same data set of the AMS 200 being read
multiple times in succession.
With the Interbus deactivated (Interbus
OFF
via control panel/display), bit
3
1 remains stati-
cally set to binary
1
. Bit
3
0 … bit 0 are statically set to binary
0
.
A deactivated AMS 200 can be recognised on the process data monitor of the Interbus mas-
ter by means of the data double word 80 00 00 00
H
.
Continuing participants are addressed even with the Interbus deactivated.
Bit 0 … Bit 22
Measurement value
:
Representation of the measured distance, Gray coded with a resolution
of 1 mm.
The coding of the measurement value can be switched from
Gray
(default) to
binary
. The setting can be found in the
Parameter
->
Inter-
bus
->
Coding
menu.
Bit 2
3
Sign
of the measured distance:
0 = positive distance value
1 = negative distance value (e.g. through the use of the offset function)
Bit 24 … Bit 25
Reserved, statically set to binary
0
Bit 26
TMP
- Temperature monitoring warning.
Above/below permissible internal device temperature.
Bit 27
LSR
- Warning laser prefailure message.
Laser diode aged, device still functional,
please initiate replacement or repair.
Bit 2
8
ATT
- Received signal warning.
Laser emission window or reflector dirty.
Bit 29
PLB
- Plausibility error.
Implausible measurement value. Possible causes:
• Light beam interruption
• Measurement range exceeded
• Internal device temperature considerably above/below limit
• Traverse rate >10m/s.
Bit
3
0
ERR
- Internal hardware error.
The device must be sent in for inspection.
