High Trip Point limit: High limit to trigger trip point condition if Input Value (I 0x900F,
SI 0x01) is above this limit.

For a fix limit set value to 0x800F1100 (High Trip Point Limit).
For ATM Mode set value to 0x800F1300 (Percentage High Trip Source).
Percentage of High Trip Source: Percentage of Piezo Sensor Value (I 0x60010, SI
0x11) in [%].
Low Trip Point Limit: Low limit to trigger trip point condition if Input Value (I 0x900F,
SI 0x01) is below this limit.

This chapter describes the configuration area for the PSG.
The High Trip Point is calculated by:
High Trip Point = Value *) × Percentage **)
*)
Value from Piezo Sensor (I: 0x6010, SI: 0x11)
**) Percentage High Trip Source (I: 0x800E/F, SI: 0x13)
In this case, the High Trip Point value is automatically updated by the device itself.
Any user-written value to the parameter High Trip will be refused with an abort
code.
The Low Trip Point is a fixed value:
Subindex 0x11
Subindex 0x12
Subindex 0x13
Subindex 0x14
Subindex 0x15
Subindex 0x16
Subindex 0x17
Subindex 0x18
Subindex 0x1A
