L_TbLimitInt Signal limitation (for data type "INT")
• The FB limits a signal of "INT" data type to an ad-
justable value range.
LenzeToolbox V02.05.xx.xx
L_TbMaskOut Zone masking
• The FB masks up to four parameterisable blocking
zones within a continuous signal characteristic.
LenzeToolbox V01.00.xx.xx
L_TbNeg Negation (for data type "DINT")
• The function block inverts the sign of the input si-
gnal, i.e. the input signal is multiplied by -1 and is
then output.
LenzeToolbox V01.00.xx.xx
L_TbNegInt Negation (for data type "INT")
• The function block inverts the sign of the input si-
gnal, i.e. the input signal is multiplied by -1 and is
then output.
LenzeToolbox V02.05.xx.xx
L_TbNegSel Optional negation (for data type "DINT")
• The function block inverts (optionally) the sign of
the input signal, i.e. the input signal is multiplied
by -1 and is then output.
• In contrast to the L_TbNeg
FB, this FB is only inver-
ted if the bNeg control input is set to TRUE.
LenzeToolbox V02.02.xx.xx
L_TbNegSelInt Optional negation (for data type "INT")
• The function block inverts (optionally) the sign of
the input signal, i.e. the input signal is multiplied
by -1 and is then output.
• In contrast to the L_TbNegInt
FB, this FB is only in-
verted if the bNeg control input is set to TRUE.
LenzeToolbox V02.05.xx.xx
L_TbNormalize Signal scaling
• The FB scales any signal to a parameterisable refe-
rence variable.
LenzeToolbox V01.00.xx.xx
L_TbPIController Simple PI controller with different control functions
and parameterisable limitation
LenzeToolbox V01.00.xx.xx
L_TbPT1Filter PT1 filter
• The FB filters and delays analog signals.
LenzeToolbox V01.00.xx.xx
L_TbRateAction Rate action function to compensate disturbing low
passes
LenzeToolbox V01.00.xx.xx
L_TbSampleHold Sample & Hold (for data type "DINT")
• The FB stores a value of the "DINT" data type in or-
der to keep it even after mains switching.
LenzeToolbox V01.00.xx.xx
L_TbSampleHoldWord Sample & Hold (for data type "WORD")
• The FB stores a value of the "WORD" data type in
order to keep it even after mains switching.
LenzeToolbox V02.05.xx.xx
L_TbSelect Selector (for data type "DINT")
• The function block switches between two signals
of "DINT" data type. The switch-over is controlled
via a boolean input signal.
LenzeToolbox V01.00.xx.xx
L_TbSelectByte Selector (for data type "BYTE")
• The function block switches between two signals
of "BYTE" data type. The switch-over is controlled
via a boolean input signal.
LenzeToolbox V02.02.xx.xx
L_TbSelectWord Selector (for data type "WORD")
• The function block switches between two signals
of "WORD" data type. The switch-over is cont-
rolled via a boolean input signal.
