Details of the Implicit Exchange Objects of the IODDT of Types T_WEIGHING_ISPY101 and T_WEIGHING_ISPY101_2
(Original Document)
About us
Introduction
This topic describes the implicit exchange objects of the IODDT of types T_WEIGHING_ISPY101 and T_WEIGHING_ISPY101_2, which apply to the TSX ISP Y101 module.
Enhancement has been done to the TSXISPY101 module from version V2.2 (since CPU V2.6) to enable some advanced functions about the calibration by program. In particular the soft and forced calibration.

WEIGHT
DINT
R
Weight value (gross or net)
By default, if no taring command has been executed, the weight value is expressed as a GROSS weight. It changes to NET weight as soon as the taring command is executed or a tare has been manually introduced.
The measurement is expressed in legal format or high resolution according to the choice created at configuration.
%IDr.m.0.0
FLOW_RATE
DINT
R
Flow
Example: %IDxy.0.2 = 450 000 means that, if the scale division is equal to 1.10-2 kg, a weight difference of 45 kg has been measured between n measurements (sampling every 20 ms).
The n number of measurements is defined at configuration.
%IDr.m.0.2
TARE
DINT
R
Tare value
This word allows the current tare value to be visualized in the same format as the weight. It is memorized by the module.
It is reset to 0 at each calibration.
T_WEIGHING_ISPY101: %IDr.m.0.5
T_WEIGHING_ISPY101_2: %IDr.m.0.6
OFFSET_MEM_VAL
DINT
R
Recalibration memory (zero offset)
This word allows the offset to be visualized currently in high resolution format. This value is memorized by the module. It is reset to 0 at each calibration.
T_WEIGHING_ISPY101: %IDr.m.0.7
T_WEIGHING_ISPY101_2: %IDr.m.0.8

%IWr.m.0.4.1
UNDERLOAD
BOOL
R
Indicator that voltage is too low. The measurement is deviating. Check the field wiring and the accuracy of the sensor.
%IWr.m.0.4.2
OVERLOAD
BOOL
R
Voltage too high on module input
%IWr.m.0.4.3
SEALED_ON
BOOL
R
Sealed module
%IWr.m.0.4.4
IN_PROGR
BOOL
R
Processing in progress (Taring, Reset, etc.)
%IWr.m.0.4.5
CAL_IN_PROGR
BOOL
R
Calibration during processing
%IWr.m.0.4.6
CMD_FLT
BOOL
R
Error detected during command
%IWr.m.0.4.7
NET
BOOL
R
NET weight measurement
%IWr.m.0.4.8
STABILITY
BOOL
R
Measurement instability
This is set when the measurement is outside the stability range during the defined time. The extent of the stability range and the time are defined during configuration.
%IWr.m.0.4.9
ZERO
BOOL
R
Zero indicator. This is set when the deviation from zero is no greater than +/- 1/4 of the scale division.
%IWr.m.0.4.10
ZERO_TRACK
BOOL
R
Zero tracking indicator active
%IWr.m.0.4.11
PREDEF_TARE
BOOL
R
Predefined or manual tare indicator (language element specific to module, accessible in read only). This is set when the tare is not the result of a taring command but rather an entry by the user.
%IWr.m.0.4.12
