5.2 Main Module Specifications
Program channels: 3
Broken line data can be input into expressions.
Setting is possible of up to 32 points of the time from the start
point and the output value at that point. Straight lines can link
those specifi ed points, and the values at each elapsed time are
output.
No. of set points: 32
Elapsed time from start point: 0 to 86400 sec.
Start point time: Fixed at 0
Limitation on specifi cation of elapsed time: Only 1 output value
per specifi ed time allowed
Output values: –30000 to 30000
Rolling average: Sampling interval:
1 to 6/10/12/15/20/30 s, 1 to 6/10/12/15/ 20/30 min, and 1 hour
Set the sampling interval to an integer multiple of the MATH
interval. If it is not, the sampling interval is increased to an
integer multiple of the MATH interval. If the sampling interval is
shorter than the MATH interval, the sampling interval is set to
the MATH interval.
Number of samples: 1 to 1500
When the number of samples is not reached:
Calculates the average using the available data.
When upper/lower limit is exceeded:
If the MATH data exceeds the upper or lower limit, the data is
clipped at the upper or lower limit, and the rolling average is
computed. The upper and lower limits are ±100000000. The
decimal place is the same as that of the MATH span.
Resetting the rolling average:
The rolling average is reset when you execute the following
operations. Clear the computed value, reset the computed
value, reset the computed value of the MATH group, change
the MATH channel, or change the channel setting of the rolling
average.
Processing when dropouts occur in the computed data:
If a dropout occurs in the computed data while sampling, the
rolling average is calculated using the next computed data.
MATH alarm function: Four levels per channel
Type: Upper limit, lower limit, delay high limit, and delay low limit.
No hysteresis function available.
Loss of computed data: In the monitor screen, when the MATH performance meter
exceeds 100%, some computations at each MATH interval cannot
be completed, and loss of computed data occurs. When this
happens, the previous computed value is held. If computation
loss occurs frequently, lengthen the MATH interval to reduce the
load. To stop computation promptly, press the Stop key on the
main module.
When the volume of computations is high:
Display updating on the monitor screen, response to computation
stop operations, and other behavior may be slow. To stop
computation promptly, press the Stop key on the main module.
