MicroLogix 1400 L32-BXBA

[Christoph]

I have a project using the Micrologix 1400 L32BXBA.
i found in the manual which outputs are the Fast outputs. I know there are
a few Fast inputs as well, But I do not find a table like I did for the outputs.
Anyone know which ones are the Fast inputs or where I can find that info?
Thanks!

are fast inputs a thing? I thought that fast outputs were from those safety PLCs that could hit outputs at a much lower latency than other normal PLCs, but I didn't know that inputs could work the same way.

Does that help?

Quick answer is inputs 0-11 are your fast inputs. I've used these with encoders and flow meters.

Yes, fast inputs are a thing.


For instance, with a 5069-IB16F input module, you can set up the 1st 8 inputs (2 groups of 4) as 30KHz counters. It works really well with flow meters. Also, a heck of a lot cheaper than an HSC module.

that's really cool!

Thanks that helps first 12 inputs are High speed. Thanks!
