13.2.2.4 Tolerance window
Function A check is performed to ensure that a tolerance
band defined by the "Threshold Hi" and "Threshold
Lo" inputs is present. Two flags indicate that
user-defined limit values have been exceeded.
The maximum, minimum, peak-to-peak and mean
value are also generated.
The process is started and stopped by
edge-sensitive digital signals.
A second input signal is captured when new peak
(min or max) was detected.
All outputs are reset at the start.
All outputs are held after stop until the next start.
The outputs are continuously updated during
operation.
The mean value output can accumulate a
maximum of 100,000 measurements. This is
equivalent to a recording time of 5.2 s at 19,200
measurements/s.
(All these functions can also be performed with the
other function blocks.)
Inputs Input 1
Input 2
Start : Starts the measurement
Stop : Ends the measurement
Upper threshold: After x has exceeded this value, the
"Limit Switch Hi" output is set until the next start.
Lower threshold: After x has fallen below this value, the
"Limit Switch Lo" output is set until the next start.
