Offset Customer Specific
Customer-specified Offset which shall be added to the Value parameter of the
Analog Input Sensor instance.
The Offset Customer Specified parameter is a value added from a Zero Adjust
Service to the reported pressure value.
Value shall be calculated as:
Value
*)
= Reported pressure value + AZO
**)
+ OCS

The High Trip Point is calculated by:
High Trip Point = Value

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:
The value defined in Low Trip Point Limit is compared with the pressure value
referenced by the Source Index parameter.
