Siemens Building Technologies field devices: XWP automatically enters the
combined values [Slpe] and [Icpt] (for the signal type, the field device and its
measurement or positioning range) on the I/O block.
Third-party field devices: You can calculate the value [Slpe] and [Icpt] using
the Intercept Calculator.
[Slpe] and [Icpt] Analog Input
In the Desigo PX modular automation stations, the analog input block is used
with the following TX-I/O and PT-I/O modules:
