The actual position information from the encoder which
arrives at the 1P 241
Special function for calculating an average value from up to
15 consecutive actual values (for analog submodule)
Connection to the device bus of the PLC
Four bits of a measured value indicating a decimal expo–
nent (units of thousand, hundred, ten, and one)
Proximity switch
Battery back–up for memory; not available with the 1P 241;
the battery back– up of the programmable controller is not
used for the 1P 241.
Relative byte O (i.e., the hardware–based setting of the
module address)
The range between a selectable start and end value,
where a reaction is desired
Group of single pulses with which the actual value is read
in for synchronous–serial encoders
Elements and connectors required for the per channel
signal conditioning
Central processor clear (if CPKL = 1, a reset is made)
Central module
Data list for the function block
Data block
Plug–in type of module that allows the conditioning of the
signals for each channel of the connected position
encoder and allows the conditioning of the encoder supply
voltages
Program stored on the module
Most significant part of a 16–bit word
Adjustable "unfocus" for "jumpy" actual values (only for
analog submodules)
