Title: Filtering available in BX analog module config
Post by: Controls Guy on September 16, 2020, 12:25:38 PM: I noticed there is a filter option in the BX-04AD-3 but not the BX-04AD-2B. I assume this means the 3 does filtering but not the 2B?

If so, that puts the feature comparison for the 3 vs. 2B at like 5-0! 8)

That is correct. Filtering is a new feature in the -3s and UTs.

Given enough channels, I suppose FILTER starts to impact scan time. The micro in the module was bored most of the time, so...

;D Plus it's nice to clean up the ladder so you can focus on the actual logic without having to look at overhead stuff.

I'm sure this could be addressed. Do you need to change it often, or is this just an initial setup tuning issue?

Initial setup/tuning/troubleshooting scenarios. Or changing a sensor out with another one and needing to dial in the values.

Post by: jrayb on September 18, 2020, 10:27:55 PM: What Bolt said. Basically during intiial setup or changing out sensors then needing to adjust the filter time to smooth everything out.
