Description

Behavior

Interrupt Immediately—Complete immediately at
current level.

Interrupt at End of Cycle—Complete the current
cycle before ending the branch.

For example, when a crack limit is detected, the cycle
can be finished rather than immediately stopped to
obtain accurate test results.

Stay immediately at current level. The Stop At button
causes a stop at the end of the current cycle.

Stop

Hold at the end of the current cycle.

Cycle + DAQ

Cycle + DAQ Activity Overview

Cycle + DAQ Activity Icon

The Cycle + DAQ composite activity combines two otherwise standalone activities:

Cycle activity

DAQ (Data Acquisition) activity

This composite activity is hardcoded to use the SegmentCount signal to process data in block mode with
the “CycleCount” variable used as the counter. For Cycle + DAQ activities, two segment counts = a cycle
(increments a cycle count).

Important:

These composite activities include hardcoded settings that simplify the setup of data acquisition for
cyclic testing.

Cycle activity

Use the Cycle activity to command the Control signal to cycle between two different end levels at a
specified frequency, using a specified wave shape, for a specified number of cycles. Two end levels form
one cycle. The number of cycles determines the required number of end levels. The frequency determines
the speed required to achieve the end levels.
