Runtime Function
2 μs
... converts a bipolar input signal into a unipolar output signal.
3 μs
... adds / subtracts analog input signals.
2 μs
... switches between two analog input signals.
2 μs
... ANDs three binary signals.
7 μs
... combines two analog signals arithmetically.
•
L_Arithmetik_2 is available from version 11.00.00.
5 μs
... compares two analog signals and can be used e.g. to implement a
trigger.
•
L_Compare_3 is available from version 11.00.00.
1 μs
... provides two stable states depending on the input signals.
2 μs
... delays binary signals.
2 μs
... provides a binary output signal which is generated by the logic
combination of three input signals.
•
L_DigitalLogic_3 is available from version 11.00.00.
3 μs
... can amplify an analog input signal and then add an offset to it.
• Gain and offset can be set via FB inputs.
5 μs
... can interpolate a position setpoint and/or an analog value e.g. to
compensate for larger bus transmission cycles or to continue signal
characteristics if data telegrams are missing.
5 μs
... can be connected upstream to the
implement a switch-off positioning at limit switch.
10 μs
... replaces a hardware motor potentiometer as setpoint source.
4 μs
... multiplies the analog input signal with a factor.
2 μs
... negates an analog input signal.
2 μs
... inverts a digital input signal.
50 μs
... contains a ramp generator with comprehensive parameterisation and
control options to condition a setpoint signal.
4 μs
... can add an offset to an analog input signal and amplify it afterwards.
• Offset and gain can be set via FB inputs.
