Threshold with hysteresis
Contents

1.Description

This module sends telegrams if a threshold value (TV) is run through from below or if two threshold values are run through from above. Additional output values are described in the value table (below).

2.Inputs

No.NameInitialisationDescription
1E1 TV 10
Threshold value 1 - the lower threshold value (TV) of the logic node is specified here.
2E2 SV 20
Threshold value 2 - the upper threshold value (TV) of the logic node is specified here.
3E30
Signal - the communication object to be processed is assigned here.

3.Outputs

No.NameInitialisationSBCDescription
1A1 (>SV2 Hyst SV1) (sbc)0sbc
This output sends a 1 if the value of the input signal greater than threshold value 2 with hysteresis is threshold value 1. The telegram is sent once when the value is exceeded. For this output to send a 1, the input value must have run through threshold value 1 from below beforehand. A 1-bit value is output. The output does not send during a restart.
2A2 (d>0sbc
This output sends a 1 if the value of the input signal less than threshold value 1 with hysteresis is threshold value 2. The telegram is sent once when the value is exceeded. A 1-bit value is output. The output does not send during a restart.
3A3 (>SV2)0s
This output sends a 1 if the input value is above threshold value 2. A 1-bit value is output.
4A4 (d>0s
This output sends a 1 if the input value is below threshold value 1. A 1-bit value is output.
s = send, sbc = send by change
