SSC X Parameter
This parameter represents the currently set switching
points (setpoint 1 and setpoint 2). The switching point 1
(setpoint 1) is active in all switching modes and can be
taught. Switching point 2 (setpoint 2) is only active in
Two-Point or Window Mode and is otherwise deactivated.
If a setpoint is deactivated, it is set to the value
0x7FFFFFFC (LSSC) (No Measurement Data) and it is also
not possible to change the value.
Moreover, it is possible to deactivate a switching channel
(SSC) in this way. Here, the value 0x7FFFFFFC (LSSC) (No
Measurement Data) must be set in one of the activated
setpoints.
Transducer Value
The current measured value of the sensor can be output in
the LSSC via index 0x01B2 (434).
This Transducer Value corresponds to the raw measured
values of the system. The data are not further processed
or prepared and therefore neither linearized nor calibrated.
The value may differ between different sensors. The result
of a measurement can therefore not be transferred when
sensors are replaced.
