Reference channel: Measurement channel
MATH channels*
Communication input channels
Flag input channels
MATH constant
Program channels
* If an expression refers to its own channel or a channel of a
larger number than its own channel, the data from the previous
MATH interval is used.
Communication input channels: 300
Numerical values in expressions can be substituted using
communication input.
Precision: Mantissa, 5 digits; exponent, 2 digits
Range: –9.9999E+29 to –1.0000E-30,0,1.0000E-30 to
9.9999E+29
Flag input channels: 60
Flag value can be substituted in computational expressions.
Range: 0, 1
Varies according to the operation of the Event/Action function.
Program channels: 3
Broken line data can be input into expressions.
You can set time since the start point (set in units of seconds) and
the output values during that time using up to 32 points. Straight
lines link those specified points, and values corresponding to the
elapsed times are output.
No. of set points: 32
Elapsed time from start point: 0 to 86400 sec.
Start point time: Fixed at 0
Limitation on specification of elapsed time: Only 1 output value
per specified 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.
