The threshold detector functions are always active even if the source and destination are not routed to valid parameters. If the source is not a valid
parameter then the source value is taken as 0. The update rate for each of the threshold detector functions is always 4ms.
The following description is for threshold detector 1, but threshold detector 2 operates in the same way. The level of the parameter defined by
Threshold Detector 1 Source
(12.003) is converted to a percentage and compared to
Threshold Detector 1 Level
(12.004) with hysteresis to give
Threshold Detector 1 Output
(12.001) as follows:
Source
Threshold Detector 1 Output
(12.001)
Source
0
Lower threshold ≤ Source
No change of state
Source ≥ Upper threshold
1
Lower threshold =
Threshold Detector 1 Level
(12.004) -
Threshold Detector 1 Hysteresis
(12.005)
Upper threshold =
Threshold Detector 1 Level
(12.004) +
Threshold Detector 1 Hysteresis
(12.005)
The output value can then be inverted with
Threshold Detector 1 Output Invert
(12.006) before being routed to the destination defined by
Threshold Detector 1 Destination
(12.007).
