8001 0x12 REAL x RW 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 ***)
*)
Value (I: 0x6000, SI: 0x11)
**)
A ccumulated Zero Offset (I: 0x9000, SI: 0x01)
***)
O ffset Customer Specified (I: 0x8001, SI: 0x12)
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:
The value defined in Low Trip Point Limit is compared with the pressure value
referenced by the Source Index parameter.
