L_DevParReadFix One-time or cyclic reading of parameters
• Only internal parameters (codes) of the controller
can be read.
•In contrast to the L_DevReadParDInt
FB, the para-
meter of this FB to be read is addressed via FB in-
puts and not via parameters.
LenzeDevice9400
V02.00.xx.xx
L_DevParWriteFix One-time or cyclic writing of parameters
• Only internal parameters (codes) of the controller
can be written.
• In contrast to the L_DevWriteParDInt
FB, the pa-
rameter of this FB to be written is addressed via
FB inputs and not via parameters.
LenzeDevice9400
V02.00.xx.xx
L_DevPositionerStateDecoder Status signals of the basic function "Positioning"
(SB LS_Positioner)
LenzeDevice9400
V02.00.xx.xx
L_DevReadParDInt One-time or cyclic reading of parameters of "DINT"
data type
• Only internal parameters (codes) of the controller
can be read.
LenzeDevice9400
V01.00.xx.xx
L_DevSMControlDecoder Control signals from the SM3xx safety module
LenzeDevice9400
V02.00.xx.xx
L_DevSMControlEncoder Control word for limiter
• The FB generates the bit-coded control signal
dwControl from individual boolean control sig-
nals for the SB LS_Limiter and thus allows control
of the basic function "Limiter" if no SM3xx safety
module is available.

V02.00.xx.xx
L_DevWriteParDInt One-time or cyclic writing of parameters of the
"DINT" data type
• Only internal parameters (codes) of the controller
can be written.
