Maximum Number of Timed Loops With a Single Timing Source in LabVIEW

Issue Details

I am using timed loops in a deterministic sequencing application that opens and runs a bunch of loops asynchronously. The configuration I am testing needs 100+ timed loops running off a single software-triggered timing source. I am getting error -800: Creating another timed structure exceeds the maximum allowed number of simultaneously active timed structures. What is the maximum number of timed loops that I can use?

Solution

Until LabVIEW 2022 Q3 the maximum number of timed loops was 125. This issue was fixed in LabVIEW 2023 Q1 (bug ID 1791074): LabVIEW Real-Time Module 2023 Q1 Bug Fixes. The max got bumped up to around 1024 in this release.
