Loop

Basic

Module: FoundationLite

Generates a loop that ends at the first invocation with False on the input.

Applications

Put this filter into a task that should have a loop, but does not have any other loop generators (e.g. GrabImage).
Name Type Description
Input value
 inShouldLoop Bool If 'True' the loop will be continued
Input value
 inDelay Integer Time between iterations in milliseconds

Examples

Description of usage of this filter can be found in examples and tutorial: HMI Configuration Page, IO Serial Port Communicator, Brick destroy (Game), Parallel Image Saving, Parallel Enumeration, Dealing with domain errors using the error handlers, TcpIp Shoutbox Server, Using HMI multipanel control.

Remarks

It is also possible to end Loop immediately under certain condition. For such case use Exit.

All Enumerate* filters (such as EnumerateImages or EnumerateCombinations) provide looping themselves, without additional Loop filter.

Complexity Level

This filter is available on Basic Complexity Level.

  • EnumerateCombinations – In each consecutive iteration produces a consecutive combination of integer numbers.
