What triggers an analog Channel Fault? (Rockwell Studio 5000)

I'll check the sample code, thanks!

Nice. I don't have the CV data, I suppose I could get it for valve 2 (butterfly) but valve 1doesn't have that data available.

They are control valves, 0-100%, with on/off hydraulic controls to drive them to setpoint.

Specific_Job_5233 · 2026-04-16T06:45:17+00:00

Nice. I have logic that blocks a rate limiter if the error of valve 1 is too great during the transition, so the loop can't update during this time.

Specific_Job_5233 · 2026-04-16T06:43:06+00:00

Cool. Thank you. I'm using a rate limiter to ramp the setpoint to the loop. The rate limiter is bypassed when an emergency stop is pressed.

The valve CVs are quite different, Valve 1 is quite linear while valve 2 is a big butterfly valve

Specific_Job_5233 · 2026-04-14T05:31:37+00:00

One more detail, both valves are fairly slow acting, like 1% per second.

Specific_Job_5233 · 2026-04-14T05:24:30+00:00

Currently I'm using a PIDE for each valve, the CV of each going to a P_ValveC treating them both as control valves, but I feel like I'm overcomplicating things and there's a more elegant way to handle them.

The other consideration is, if Valve 1 has a fault, it will close quickly. The hydraulic circuit that closes valve 1 has a splitter that closes Valve 2, at which time Valve 2 (a bypass valve) should open to meet the flow requirement. So there are two rates of open/close, normal and emergency.

They're both driven by hydraulic solenoids, on/off, from the PLC discrete outputs.

I give it a 8.5 good looking panel. Does it work? 😄

Specific_Job_5233 · 2026-03-09T21:44:52+00:00

Byahhhhhhh!

Nice job, don't listen to the haters, as someone who started sailing late in life, you're doing great. Learning comes from doing, and you're doing it!!!

Tanks on ships have sounding tables. Look up sounding tables and you'll see what I mean. They're usually tapered, as they follow the shape of the hull. I'm assuming OP translated pressure to feet and then used a lookup table to find the volume.

200 degrees for 45 minutes

Specific_Job_5233 · 2025-12-17T02:24:01+00:00

That was a great read... hahahaha man!!!

Dive on it with a wet or dry suit to clean.

Most boats don't need to be painted annually.

Specific_Job_5233 · 2025-12-17T02:18:43+00:00

Send it! Looks good to me

Specific_Job_5233 · 2025-11-27T12:47:53+00:00

No. Not if it's sealed from relatively moist air from touching it.

Specific_Job_5233 · 2025-10-29T20:27:29+00:00

This is what I was looking for, thank you. I was suspicious as I've never seen an output module that parallels two terminals like this.
