5.6.12.5 Moving Average
A Calculated Moving Average point calculates the continuous average of the measured or processed value
of a selected point. The result is the weighted average of the present reading and the previous average
value. Therefore, this type of point can be used to smooth out noisy or erratic signals and to attenuate the
effects of sudden transitions. Calculated Moving Average Points are only programmable for point
numbers A through F. The Point Setup menu for Moving Average will be displayed and may require
programming the following parameters:
Point Tag Section 5.6.5.1
Decimal fix Section 5.6.5.4
Basepoints Section 5.6.5.12 (Pick starting and ending Basepoints)
Time Period Section 5.6.5.14
Engineering Units Section 5.6.5.9
Alarm Setpoint Section 5.6.5.10
Chart Scale Section 5.6.5.11
5.6.12.6 Time Average
Calculated Point Types with a Point Range of Time Average calculate a continuous average of the measured
or processed value of a selected point. The result is a weighted average of the present reading and the
previous average value. This value can be used to smooth out noisy or erratic signals and to attenuate the
effects of sudden transitions. The Point Setup menu for Time Average will be displayed and may require
programming the following parameters:
Point Tag Section 5.6.5.1
Decimal fix Section 5.6.5.4
Basepoint Section 5.6.5.12
Engineering Units Section 5.6.5.9
Reset Control Section 5.6.5.13
Alarm Setpoint Section 5.6.5.10
Chart Scale Section 5.6.5.11
5.6.12.7 Gated Timer
The Gated Timer function allows a timer, measuring in seconds, to be controlled by a ‘gate’ from a logic
point. For example, if a point is measuring temperature and you wanted to know the total amount of time
the temperature measured by this point is above or below a certain level, a Conditional Point can be
programmed to be ‘true’ only when the temperature is above or below a set level. A Gated Timer Point can
then be programmed to be turned ON only when the Conditional Point is in the true state. The Gated Timer
Point will then only be timing when the temperature is above or below a set level. The timer will continue
to accumulate time, in seconds, each time it is turned on. The Gated Timer Point can be reset at
programmable time intervals and alarms can be set to alarm if the timer total goes above a programmed
time interval in seconds. The Point Setup menu for Gated Timer will be displayed and may require
programming the following parameters:
Point Tag Section 5.6.5.1
Gate Control Section 5.6.5.15
Engineering Units Section 5.6.5.9
Reset Control Section 5.6.5.13
Alarm Setpoint Section 5.6.5.10
