16.1 Function blocks
This chapter describes the function blocks which are available for the controller in the FB
Editor.
Overview of function blocks available
The system blocks are described in the following chapter "System blocks". ( 855)
Function block Runtime Function
L_Absolute_1
2 μs ... converts a bipolar input signal into a unipolar output signal.
L_AddSub_1
3 μs ... adds / subtracts analog input signals.
L_AnalogSwitch_1
L_AnalogSwitch_2
L_AnalogSwitch_3
2 μs ... switches between two analog input signals.
L_And_1
L_And_2
L_And_3
2 μs ... ANDs three binary signals.
L_Arithmetik_1
L_Arithmetik_2
7 μs ... combines two analog signals arithmetically.
• L_Arithmetik_2 is available from version 11.00.00.
L_Compare_1
L_Compare_2
L_Compare_3
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.
L_DFlipFlop_1
1 μs ... provides two stable states depending on the input signals.
L_DigitalDelay_1
2 μs ... delays binary signals.
L_DigitalLogic_1
L_DigitalLogic_3
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.
L_GainOffset_1
L_GainOffset_2
L_GainOffset_3
3 μs ... can amplify an analog input signal and then add an offset to it.
• Gain and offset can be set via FB inputs.
L_Interpolator_1
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.
L_JogCtrlExtension_1
5 μs ... can be connected upstream to the L_NSet ramp generator to
implement a switch-off positioning at limit switch.
L_MPot_1
10 μs ... replaces a hardware motor potentiometer as setpoint source.
L_MulDiv_1
4 μs ... multiplies the analog input signal with a factor.
L_Negation_1
2 μs ... negates an analog input signal.
L_Not_1
L_Not_2
L_Not_3
2 μs ... inverts a digital input signal.
L_NSet_1
50 μs ... contains a ramp generator with comprehensive parameterisation and
control options to condition a setpoint signal.
L_OffsetGain_1
L_OffsetGain_2
4 μs ... can add an offset to an analog input signal and amplify it afterwards.
• Offset and gain can be set via FB inputs.
