ILConTlC (ITF)

INTERFACE ILConTlC EXTENDS ILConC, ITimeLimited, ITimingControlled

In order to build a function block with a LConTlC behaviour, its action provider has to be decorated with this interface. This will determine the state machine which then forces the function block to the appropriate LConTlC behaviour.

See Decorators for more information about the concept.

Starting:

⇒ StartAction is running, until xComplete is TRUE, xBusy ⇒ TRUE

Executing:

⇒ CyclicAction is running until xComplete is TRUE

Cleaning:
⇒ CleanupAction is running. At its end the ExitAction is probably executed one time.
After a Ready Condition as input, only the output state
Error (eErrorID ≠ ERROR.NO_ERROR) is possible.
After a Error Condition as input, only the output state
Error (eErrorID ≠ ERROR.NO_ERROR) is possible.
After a Abort Condition as Input, only the output states
Resetting or Error (eErrorID ≠ ERROR.NO_ERROR) are possible.
(xBusy is still TRUE!)
Error:

xError ⇒ TRUE, eErrorID ≠ ERROR.NO_ERROR, xBusy ⇒ FALSE

Resetting:
⇒ ResetAction is running, until xComplete is TRUE.
After that:
- the output xError will be set to FALSE.
- The output eErrorID will be set to ERROR.NO_ERROR.
