ANALOG INPUT BLOCKS (VCI, TII, TI, RI, RTI, RTTI)
7-25
milliseconds, four samples would be filtered using the following first
order filter calculation:
Value = Previous value + (0.15 / (0.15 + FILTIME)) *
(sampled value - Previous value)
where 150 milliseconds is the base sample rate for
analog inputs and FILTIME is the filter time =
0.150 / 0.150 + (INTn/2) and INTn is one of
the Group Scan Intervals from Interface
Block
USER 2 User allows a filter time to be configured (FILTIME) into the filter
calculation.
VCI 14 Filter Time (FILTIME) .........................................................................................................CWR
TTI 14 Filter Time (FILTIME) .........................................................................................................CWR
TI 13 Filter Time (FILTIME) .........................................................................................................CWR
RI 13 Filter Time (FILTIME) .........................................................................................................CWR
RTI 13 Filter Time (FILTIME) .........................................................................................................CWR
RTTI 14 Filter Time (FILTIME) .........................................................................................................CWR
The filter time attribute specifies a value equal to time in minutes for the filter. This value is
either the user (USER) input value or a calculated (AUTO) value based on the task scan rate.
value Any floating point value in minutes
where
0.0 = no filtering (last sampled value is the input value)
1.0 = a 1 minute
1000.0 = 1000 minutes (maximum value)
Note that exceptionally large values tend to maintain the previous value whereas very small
values tend to maintain the most recent sampled value.
VCI 15 Output Range - Top (OUTHI) ............................................................................................CWR
RI 14 Output Range - Top (OUTHI) ............................................................................................CWR
User scaled high floating point value for VCI and RI blocks. Represents the 100%
output value in engineering units.
VCI 16 Output Range - Bottom (OUTLO) ....................................................................................CWR
RI 15 Output Range - Bottom (OUTLO) ....................................................................................CWR
User scaled low floating point value for VCI and RI blocks. Represents the 0%
output value in engineering units.
TTI 15 Transmitter Range - Top (TRANSHI)................................................................................CWR
RTTI 15 Transmitter Range - Top (TRANSHI)................................................................................CWR
Transmitter top of range for TTI and RTTI blocks. TTI blocks are specified in result units of
microvolts (see transmitter tables for temperature equivalents of microvolts). RTTI blocks are
specified as a temperature value where the scale is determined by the Temperature Scale
attribute.
