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):
