Not in use
Here T_DW1 provides the weight information (32-bit signed integer or 32-bit signed floating point, see chapter
8.6.2; WXX = Weight bit XX; W31 = MSD; W0 = LSD ) and T_DW2 provides the status as indicated below.
Bit no. TxPDO 2 (T_DW2) Description
31...29 Error
000 No error
001 ADC out
010 ADC over
011 ADC under
100 System error
101 FT-11 not in weighing mode
28 Not used Always 0
27 Multi range (MR) Single range: always 0 Multi range: 0 = 1. Range / 1 = 2. Range
26 Digital input 3
25 Digital input 2
24 Digital input 1
Status input bit (1 = active)
23 Digital output 3
22 Digital output 2
21 Digital output 1
Status output bit (1 = active)
20 Not used Always 0
19 Net 0: Gros mode; 1: Net mode
18 Motion 0: No motion; 1: Motion
17 Data Ok 0: Check the error bits; 1: Scale is operating properly
16 Data update in progress
0: PLC should not use the data; 1: use the data
(if 0, the instrument was updating the PLC interface shared memory while data
was read. The PLC interface should ignore this data and rescan.)
15...0 Not used Always 0
Bit no. T_DW2 Description during the calibration
0000 0001 Calibration Timeout – Restart calibration
0000 0010
ADC Error – Re-energize the instrument
– If seen again, change board.
0000 0011
Instrument cannot be calibrated – Check load cell cable
– Re-energize the instrument
0010 0010
Instrument cannot be calibrated – Load cell signal is too low or too
high
0010 0011
Calibration Error
– Calibration test weight is too small, increase calibration weight
– Check load cell connections
0010 0101
Scale unstable – Wait until scale becomes stable
– Check grounding wiring
15 … 8 Calibration error
0010 0110 Calibration Jumper is not installed- Check Calibration jumper
0000 0001 Ready for calibration
0000 0011 Zero calibration in process
0000 0100 Span calibration in process
7...0 Calibration status
0000 1001 Calibration error (see bit 15...8)
