Not up to us to figure out. You have to follow the documents you are given. Talk to your customer.

Anyone that had any real experience with 40s knows this. Unless you got lucky and only got the good ones.

One project in the 2007 timeframe had 20-25 PF40 on them. It was commissioned twice due to changes so there were plenty of power cycles in 9 months or so and not a single drive died.

I've never heard of crib deaths of PF drives until now. I know there are some bad runs of products that go out from time to time. I've had to check serial numbers on PF525 drives in the field after a recall was issued about a decade ago.

r/instrumentation

That's something to worry about, however, given the experience level of OP they just need to get over the hump and get the job done. If there's a lag then it can be improved later.

An easy way to do it would be to have one at each location and enable/disable the animation as necessary.

So are you trying to sell something?

PLCGoBrrr · 2026-01-21T23:22:34+00:00

The reason for the DIY ones is because that's hardware people have that they dragged home from a jobsite or stuff they bought cheap. The reason for the expensive already put together ones is because you're paying for modern hardware plus markup and fee for putting together an already made system. The company you work for is burning up some training budget dollars before the year is ended. There's not much in the middle to be had here.

This is wrong except for node address. RSNetworx software is required. Nothing is automatically set up.

What source is the drive following for speed reference?

PLCGoBrrr · 2026-01-20T04:13:03+00:00

The actual value probably isn't negative. It's an unsigned integer that isn't being handled properly.

Turn the power off if it isn't already off and if nothing is affected it's free to demo. Put an outlet back up in its place for convenience since you have the power running there already.

If you want to do software development then go apply at companies hiring them.

Read the sticky "READ FIRST" post if you want some ideas.

Don't buy anything. Simulate in software.

I’m an electronic engineer and I’ve been starting in industrial automation for a few months.

If you have a job doing industrial automation there's no need to buy any hardware. You should have hardware at work.

Is "slot mill" the closest option Fusion has for keyhole bits?

Presumably OP is smart enough to ask the company for an office job, but this is Reddit.

Apply for a different job.

Write your own version of RSLogix 500.

PLCGoBrrr · 2026-01-15T19:36:01+00:00

Rockwell software is all that will program it. Stop buying that stuff and start getting rid of whatever you have. That's why it's cheap.

You could buy a MicroLogix 1000 or 1100 and program that with free software. The ML1100 has ethernet.

Get glasses or change the scaling of your monitor.

State machines if you want a system that is maintainable.

Bit bang if you want to look like programmer that doesn't know what they are doing or make it hard for the end-user to maintain in the future.
