Measuring range module
Measuring range modules are plugged into the analog input modules for adapta-
tion to different measuring ranges.
Module filtering mode
By operating mode we mean:
1. The selection of an operating mode of the CPU using the mode switch or the
PG
2. The type of program execution in the CPU
3. A parameter in STEP 7 for analog input modules
Monoflop time
Parameter in STEP 7 for position detection module SM 338; POS-INPUT. The
monoflop time is the time interval between 2 SSI message frames (→ Encoder
absolute).
MPI
The multipoint interface (MPI) is the programmer port of the SIMATIC S7. It is
used to access programmable modules ((CPUs, CPs), text displays and operator
panel from a central point. The nodes on the MPI can communicate with each
other.
Non-isolated
In the case of non-isolated input/output modules, the reference potentials of the
control and load circuit are electrically connected.
Normalizing
Parameter in STEP 7 for position detection module SM 338; POS-INPUT.
Normalizing right justifies the encoder value of the → encoder absolute; non-rel-
evant places are discarded.
OB
→ Organization block
Operational limit
The operational limit is the measuring or output error of the analog module over
the entire temperature range, referred to the rated range of the analog module.
