Parameter

12.001 Threshold Detector 1 Output

Short description Displays the output of threshold detector 1
Mode Open‑loop
Minimum 0
Default
Type 1 Bit Volatile
Display Format Standard
Coding RO, ND, NC, PT
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
Source < Lower threshold
Lower threshold ≤ Source < Upper threshold
Source ≥ Upper threshold
Lower threshold = Threshold Detector 1 Level (12.004) - (Threshold Detector 1 Hysteresis (12.005) / 2)
Upper threshold = Threshold Detector 1 Level (12.004) + (Threshold Detector 1 Hysteresis (12.005) / 2)
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).
