program elements) were reset to default. A cold start may be triggered
automatically (for example, due to power failure, loss of dynamic data in memory).
Communications Processor
Communications processors are modules for point-to-point and bus connections.
Compress
The PG online function “Compress” is used to shift all valid blocks in the RAM of
the CPU evenly and without any gaps to the beginning of the user memory. All
gaps caused by deleting or correcting blocks are thus removed.
Configuration
The configuration is the selection and putting together of the individual components
of a programmable logic controller (PLC).
Configuring
Configuring is the assigning of modules to racks or slots and (with signal modules)
addresses.
Consistent data
Data associated with each other in the same context and which may not be
separated
All values of analog modules must be treated as consistent data, for example. That
is, a value read at different times from an analog module may not be corrupted.Counters are an area in the system memory of the CPU. The contents of these
counters can be changed using STEP 7 instructions (for example, up counter,
down counter).
CP
→ Communications Processor
CPU
Central processing unit of the S7 programmable controller with processor,
arithmetic unit, memory, operating system, and programming device interface.
Cycle time
The time a → CPU requires to execute the → user program.
Cyclic Interrupt
A cyclic interrupt is generated by the CPU periodically according to a
programmable time interval. A corresponding organization block is then executed.
D
Data Block (DB)
Data blocks are areas in the user program which contain user data. There are
shared data blocks which can be accessed by all logic blocks, and there are
instance data blocks which are associated with a particular function block (FB) call.
Data, Static
Static data are data which are used only within a function block. These data are
stored in an instance data block belonging to the function block. The data stored in
the instance data block are retained until the next function block call.
Data, Temporary
Temporary data are local data of a block that are stored in the L stack during
processing of the block and that are not retained after processing.
Default Setting
A default setting is an expedient basic setting which is always used when no other
value is preset by a parameter.The diagnostic buffer is a retentive area of memory within the CPU which
stores the diagnostic events in the order they occurred.
Diagnostic Interrupt
Modules with diagnostics capability signal system errors to the CPU by
means of diagnostic interrupts.
DP Master
A master which is compliant with EN 50170, Part 3.
Interconnects the CPU and the distributed I/O system. Exchanges data via
PROFIBUS DP with the distributed I/O and monitors the PROFIBUS DP.DP SlaveA slave which is operated on PROFIBUS with PROFIBUS DP protocol andcompliant with EN 50170, Part 3.Prepares the data of encoders and actuators locally for their transfer to the CPUvia PROFIBUS DP.
DPV1
Enhancement of distributed I/O to EN 50170. The results were incorporated into
IEC 61158 / IEC 61784-1:2002 Ed1 CP 3/1. The term DPV1 is used in the SIMATIC
documentation. The new version contains enhanced and simplified functionality, for
example, the extension of acyclic services with new interrupt functions.
The DPV1 functionality is integrated into IEC 61158/EN 50170, Volume 2,PROFIBUS.
EElectromagnetic Compatibility (EMC)
Electromagnetic compatibility is understood to mean the capability of electricalapparatus to operate without faults in a given environment, without affecting that
environment in an unacceptable manner.
Equipotential BondingAn electrical connection (equipotential bonding conductor) that ties the exposed
conductive parts of an item of electrical equipment and extraneous conductiveparts to the same, or approximately the same, potential in order to prevent
disturbing or dangerous voltages between these parts.Error display is one of the possible responses ofthe operating system to a run-time
error. The other possible responses include: error response in the user program,STOP mode of the CPU.
Error Handling via OBWhen the operating system detects an error (for example, STEP 7 access error), it
calls the specific organization block (error OB) for this error, where the further
response of the CPU can be specified.Error Response
