Using the filters please note, that the optocoupler inputs on one hand have

response times much longer than 1µs and on the other hand may vary in

steepness of rising and falling curves. This is not considered at the filter

configuration, as the optocouplers may show varying component tolerances.

The user has to allow for this by himself. Not considerung these switching

times may lead to a filtering out of signals at the optocoupler input, even

though theoretically they are applied long enough.

5.7 Interrupt functions of the optocoupler inputs

To detect changes to the optocoupler inputs without periodically querying the
input state via PC, the OPTOIO-PCIe16 offers several interrupt options.
On one hand the card is aible to trigger an interrupt on one of the inputs on
a rising edge. On the other hand the card can signal to the PC a general
change of the input states by an interrupt.
For further information please see the chapter Interrupt Controller.

Zu beachten ist bei der Verwendung der Filter, dass die Optokopplereingänge

zum einen weit längere Schaltzeiten über 1µs besitzen und zum anderen

unterschiedlich steile Steigungs- und Fallkurven aufweisen. Diese werden

bei der Filterkonfiguration aufgrund von Bauteiltoleranzen unter den

Optokopplern nicht berücksichtigt und müssen vom Anwender selbst mit
einberechnet werden. Werden diese Schaltzeiten nicht mit einberechnet,

kann dies dazu führen, dass Signale am Optokopplereingang gefiltert

werden, obwohl sie theoretisch lange genug anliegen.

5.7 Interruptfunktionen der Optokopplereingänge

Um  Änderungen  an  den  Optokopplereingängen  ohne  regelmä-
ßiges  Abfragen  der  Eingänge  durch  den  PC  zu  erkennen,  bietet  die
OPTOIO-PCIe16  mehrere Interruptmöglichkeiten an. So gibt es zum einen
die  Möglichkeit,  dass  die  Karte  bei  einer  steigenden  Flanke  an  einem
der  Eingänge  einen  Interrupt  am  PC  auslöst,  oder  zum  anderen,  dass
sie dem PC durch einen Interrupt eine generelle Änderung der Eingänge
signalisiert.
Neben  diesem  Kapitel  lesen  Sie  bitte  das  Kapitel  Interruptcontroller
durch.
