DESINA
Distributed and Standardized INstAllation technique for machine tools
DESINA is an all-inclusive general concept for standardization of
installation-relevant components in terms of function and connection technology.
End-to-end usage of DESINA-compliant components can produce significant
savings in the costs of system planning, implementation and operation.
Diagnostic interrupt
Diagnostics-compatible modules use diagnostic interrupts to notify the central
CPU of system errors.
In SIMATIC S7/M7: When an error is detected or disappears (e.g. wire break),
ET 200X triggers a diagnostic interrupt, provided the interrupt is enabled. The CPU
of the DP master interrupts the processing of the user program and lower priority
classes and processes the diagnostic interrupt block (OB 82).
In SIMATIC S5: The diagnostic interrupt appears in the station diagnosis. Using
cyclical querying of the diagnostic bits in the station diagnosis you can detect
errors such as a wire break.
Diagnostics
Diagnostics means the detection, localization, classification, reporting and
evaluation of faults, malfunctions and messages.
Diagnostics incorporates monitoring functions which run automatically while the
system is in operation. This enhances system availability by reducing setup
times and outages.
Direct starter
A direct starter is a
Motor starter which switches a motor on or off directly. It
consists of a power circuit-breaker and a contactor.
Distributed I/O devices
These are input/output units that are not located in the base unit; instead, they
are distributed at some distance from the CPU. The following are examples of
such units:
ET 200M, ET 200B, ET 200C, ET 200U, ET 200X, ET 200L
DP/AS-I Link
S5-95U with PROFIBUS-DP slave interface
Other DP slaves from either Siemens or other vendors
The distributed I/O devices are connected to the DP master via PROFIBUS-DP.
