19.9 Slope [Slpe] and Intercept [Icpt]
[Slpe] and [Icpt] value exist for:
● I/O modules (PX Modular and PX Compact)
These values impact signal type (the I/O module).
● Siemens field devices
These values affect the combination of Slpe and Icpt values for the signal type, the field device and its
measurement and positioning range. XWP automatically enters these values, and they can be changed
there, e.g., to consider the line resistance of a sensor or to describe a third-party sensor.
● BACnet referencing
● PPS2 interface
The combined values [Slpe] and [Icpt] can be calculated as follows from individual values for signal type
(I/O module) and characteristic curve (field device):
