Try it on your machines before anyone else.

LScope turns an iPhone into a diagnostic instrument for Allen-Bradley® Logix controllers: live tags, trends, alarms, and a trigger that captures the thirty seconds either side of a fault. It is read-only, and it is in development.

What it needs now is to meet controllers it has never seen.

What we are asking

Point it at a real machine

LScope is being evaluated across CompactLogix® and ControlLogix® equipment. The most useful thing you can do is connect it to something else: a different processor, a different firmware revision, a program with thousands of tags. Tell us what happened.

Use it in anger, once

No test plan, no forms to fill in. Reach for it next time a machine stops and tell us whether it helped or got in the way. Both answers are worth having.

Say when it is wrong

The controller model and firmware, what you expected, what happened instead. A diagnostic snapshot from the app is worth more than a paragraph.

What you need

An iPhone running iOS 17.6 or later. Check the build requirements before accepting an invitation.
An Allen-Bradley Logix controller you have permission to connect to. CompactLogix or ControlLogix. Permission matters. Many plants treat the control network as restricted, and that is a conversation to have before you connect, not after.
A way onto that network. A USB-C or Lightning Ethernet adapter, plant Wi-Fi, or a VPN into the controls network. Routing and permissions depend on your phone and network.
The controller's IP address and backplane slot.

How iOS beta testing works

You request an invitation below.Takes a minute. Nothing is installed and nothing is committed to.
We review your request.If a testing place is available, we email the next steps and the applicable beta agreement.
After testing is arranged, Apple emails you a TestFlight invitation.TestFlight is Apple's own free app for trying pre-release software. Install it, tap the invitation, and LScope appears alongside your other apps.
Builds expire, and get replaced.Each build lasts up to 90 days. You will get new ones as things change, and TestFlight tells you when one is waiting.
Feedback is a screenshot away.Take a screenshot and shake the phone, and TestFlight sends it with the build number and your device details attached, so you never have to describe any of it.

Your name *

Email *

Where we write to you: the agreement, the instructions, and anything we need to ask.

TestFlight invitation email

Leave blank to use the address above. It does not have to be your Apple Account, but it does need to be one you can open on the iPhone you will be testing with, because the invitation is a link you tap on the device. If your Apple Account uses a different address, that is usually the safest one to give.

Company and role

Which iPhone *

Grouped by connector, because it decides which Ethernet adapter to point you at: USB-C on iPhone 15 and later, Lightning before that.

Which iOS version *

Settings → General → About → iOS Version. The major number is all we need. LScope needs iOS 17.6 or later, so this is the one answer that can rule a phone out. Better to find that now than after you have installed TestFlight.

Do you have an Ethernet adapter for your phone? *

Yes, I already have one

No, I would need one

Not sure which one I need

I would use Wi-Fi or a VPN instead

An adapter is the most reliable way onto a machine subnet, but it is not the only one. Saying you need one is not a problem. It just tells us whether to sort that out before you start.

What could you test it against? *

The single most useful thing you can tell us. Processor families, rough firmware revisions, anything unusual: a huge tag database, program-scoped tags, a machine on a routed subnet.
