The following table and figures illustrate the function of the Pulse timer.

Table 1. Pulse Timer Function

Feature

Description

Activation

Goes active if the Input goes from low to high in two consecutive executions (logic executes every 5 seconds. The Pulse timer remains active for the amount of time specified in Duration, then goes to inactive. High to low transitions do not activate this timer.

Output

Stays high as long as the timer is active. After the Duration expires, the Output goes low at the next logic execution.

Reset

Cancels timer activity and makes the output low. If the Reset goes from high to low, the timer re-evaluates the Input at the next low to high transition.

Example

Captures a short pulse on a binary input and keeps the Output True long enough so that the logic can react to it.
