6 - 112 Service Manual
The software analyses the status of these 4 (3) inputs, to determine the
value and status of the
[HIMS Density PV].
If the HIMS Density PV status is
<Good Actual>, the HIMS Density PV
value is also stored in memory in the
[Last Valid Density] entity, to allow
recovery from a power-down situation when a HIMS Density PV value is
not available.
If any of the 4 input statuses are bad, the software will check for a
[Manual Product Density] entity value to be entered. If a [Manual Product
Density]
entity value is entered, this value will be used for the HIMS
Density PV. If no
[Manual Product Density] entity value is entered, the
software will check if a
[Last Valid Product Density] entity value was stored. If
a
[Last Valid Product Density] entity value was stored, this value will be used
for the HIMS Density PV. If no
[Manual Product Density] or [Last Valid Product
Density]
entity value is found, an error will be reported.
When calculating HIMS Density, the software will check for a negative
density value. If the value is negative, the same manual or last-valid
mechanism is used as described before. If the value is positive, HIMS
Density is calculated.
When calculating HIMS Density, in order to achieve a valid result, the
software will also check if the product level is above the
[Minimum HIMS
Level]
entity value. If this condition is <True>, HIMS Density is calculated.
If the product level is below the
[Minimum HIMS Level] entity value, the
same manual or last valid mechanism is used as described before.
When calculating HIMS Density, if the
[Water Level Correction] entity is
<Enabled>, the software will check if the scanned water level <= [Distance
P1 to Zero Level]
. If this is <True>, the HIMS Density is calculated. If the
water level >
[Distance P1 to Zero Level], the same manual or last valid
mechanism is used as described before. If
[Water Level Correction] entity is
<Disabled>, the software will not check the scanned water level.
6.8.3.5 Generic HART Devices
The FCI-HT software only accepts Generic HART devices at addresses
0 and 4 through 15 with the required sensor type configured.
The generic HART devices are scanned sequentially from address 0
and then address 4 through 15. When a device is detected, initially the
HART PV unit code is checked against TABLE 6-7 in the following
order: Distance, Temperature, Pressure, and Density.
Sensor Type Accepted HART Units Abbreviation
