Staircase Timer

The staircase timer sends a false or 0 after a configured time when triggered with a true or 1.

Inputs and Outputs

Inputs

• GATE (see Logic Elements | Datapoint-Gate)

• IN
  The value input (see below) 

• DELAY
  Variable delay time in the unit set in the logic element. If a delay time of 2 minutes is set, the delay would comprise the corresponding number of minutes for an input value of 5. If 120 seconds are set, an input value of 5 would result in only 5 seconds remaining until the counter signal.

Outputs

• OUT
  The output for start signal and negated and delayed start signal

Configuration

In contrast toother logic elements, this logic element only accepts input values of the types Boolean and Integer. There is no conversion, so that it must be these specific data types. Regarding integer values, only 1 or 0 are accepted as a valid value. Any other input value will be discarded.

In order to start the staircase timer, send true or 1 to IN.

Along with the actual default delay that may be overwritten by the DELAY data point, the following options are possible

Pass through trigger signal

The logic element passes the trigger signal wich starts or retriggers the logic element through to the output.

Behaviour on value input during active delay

• Ignore

• Restart delay

Behavior on stop value (false/ 0) during delay

• Ignore

• Cancel delay without sending an end signal

• Cancel delay and send the end signal (false / 0)

Inversion of the values

In this case, the logic is inverted. In order to start the timer, a false or 0 would have to be sent, and in order to stop the timer, a true or 1 would have to be sent.
