Reading Configuration Parameters
(Original Document)
Introduction
The set of parameters entered during the configuration of the module is accessible by program in read only.
These parameters are coded in 3 words of the %KW constant area.
Coding of the Maximum Weight
The maximum weight reading, configured for the measuring channel, may be accessed with the word %KWr.m.0.0.
Coding the Measurement Unit
Reading the unit and the scale division, configured for the measuring channel, is accessible with the word %KWr.m.0.1.
The measurement unit is coded on 3 bits of the least significant byte.
The following table describes the coding of the measurement unit.

Scale Division Coding
The reading of the unit and the scale division configured for the measuring channel, is accessible with the word %KWr.m.0.1.
NOTE: The scale division is defined in the same unit as that of the measurement.
The measurement unit is coded on 5 bits of the most significant byte.
The following table describes the coding of the scale division.

Coding of the Stability (of zero, thresholds, outputs, and format)
The reading of the extent of range and the stability time and the extent of range from zero and the activity of zero tracking, of the overload threshold, the utilization of the outputs and the format of the weight values, configured for the channel measurement are accessible with the memory word %KWr.m.0.2.
