Linearity error
Denotes the maximum deviation of the measured/output value from the ideal linear
relationship between the measured/output signal and the digital value. Defined as a
percentage, relative to the rated range of the analog module.
Logic block
A SIMATIC S7 logic block contains elements of the
data block only contains data. Available logic blocks: Organization Blocks (OBs), Function
Blocks (FBs), Functions (FCs), System Function Blocks (SFBs), System Functions (SFCs).
Measuring range module
Modules installed on analog input modules for the adaptation to different measuring ranges.
Monoflop time
STEP 7 parameter for the SM 338; POS-INPUT position detection module. The monoflop
time is equivalent to interval between two SSI message frames ( → Absolute encoder.)
MPI
Multi-Point Interface. SIMATIC S7 interface for programming devices. Allows central access
to remote programmable modules (CPUs, CPs), Text Displays und Operator Panels. MPI
nodes can intercommunicate.
OB
→ Organization Block
Operating mode
Definition of this term:
1. selection of a CPU operating state using the mode selector switch or a PG
2. the type of program execution at the CPU
3. an analog input module parameter in
Operating state
Operating states known to SIMATIC S7 automation systems: STOP, → STARTUP, RUN and
STOP.
Operational limit
Represents the measuring/output error of an analog module across the entire permissible
temperature range, based on the module's rating.
