LDU 179.1 Technical Manual rev. 1.10 - February 2019 Page 25 of 45
Note:
In bipolar applications (e.g. force- or torque measurements) this parameter defines the max. output value
for input signals with negative sign. Factory default: CI =
–
999999
8.2.4. MR Set Multi-range / Multi-interval
[ SDO 2300 sub 0D ]
This command is only relevant, if CM 2 > 0 or CM 3 > 0. Is this the case, then this command defines, if the
application is multi-range or multi-interval. Permitted values are 0 (Multi-interval) or 1 (Multi-range).
Master (PC / SPS) sends
Slave (LDU 179.1) responds
Meaning
MR

OK
Calibration sequence active
MR1
OK
Setup: MR = 1 (Multi-range)
Note:
Single range applications ignore this parameter.
8.2.5. DS Set Display Step Size
[ SDO 2300 sub 0C ]
This command allows the output to step up or down by a unit other than 1.
Permitted values are 1, 2, 5, 10, 20, 50, 100, 200 and 500.
Master (PC / SPS) sends
Slave (LDU 179.1) responds
Meaning
DS

Calibration sequence active
DS50
OK
Setup: Step size 50
Legal for trade applications allow for up to 10000 intervals. The allowed step size has to be considered.
8.2.6. DP Set Decimal Point Position
[ SDO 2300 sub 0B ]
This command allows the decimal point to be positioned anywhere between leftmost and rightmost digits of the
6-digit output result. Permitted values are 0, 1, 2, 3, 4, 5 and 6. Position 0 means no decimal point.
Factory default:
DP = 3
Master (PC / SPS) sends
Slave (LDU 179.1) responds
Meaning

Setup: no decimal point
8.2.7. CZ Set Calibration Zero Point
[ SDO 2300 sub 0A ]
This is the reference point for all weight calculations, and is subject to TAC control.
Factory default: approx. 0 mV/V input signal
Master (PC / SPS) sends
