Find a servo drive and explain its activation conditions in the PLC program.
Found the servo control block FB 1343 Faulhaber MCBL. The drive is enabled when it is online, not cancelled, and a motion command (Home / Jog / Positioning) requests it.

Where is -94B1 wired, and where do I find it in the cabinet?
-94B1 is the product-detect photocell (SICK WL12-2P430) on conveyor 3. It's wired to input %I4.3 on DI module -A4, through terminal X1:11–12 in cabinet +SK3.
How did IMM01 spend its energy the week of Jan 12? Anything wasteful?
Pulled IMM01 power from the MES historian for Jan 12–18, 2026 and bucketed it by machine state:
IMM01 (kWh) Over DateTime — Weekly Trend
IMM01(kWh)
Total hours per state (Jan 12–18, 2026)
OFF 63 h ON_NO_PROD 74 h PROD 31 h
The machine drew power while idle for 74 h — more than double its 31 h of actual production. Trimming idle time is the fastest saving here.
How often should we clean the WL12 photocell on conveyor 3?
From the conveyor 3 manual (rev 04/2024):
"Clean the lenses of all photocells in the infeed section every 240 operating hours. Dust on a lens causes dropouts on the product-detect signal."
Conveyor 3 manual · rev 04/2024 Page 7
Your maintenance log shows the lens was last cleaned 312 h ago, past the 240 h interval. That lines up with the repeated photocell dropouts.
Has anyone fixed the Station 52 photocell before? What did they do?
Yes — the Station 52 photocell replacement (Tomáš Marek, Apr 23) sits at the top of the Line 4 journal, indexed alongside every recent fix:

§01 The bottleneck
You have a CMMS. You have an MES. You have Copilot.
So why do faults still take hours to fix?
$30,000–$60,000
An hour of unplanned downtime on a tier-2 automotive line.
We bet your last downtime took more hours than you would have liked.
§02 Why downtime hurts
It takes ten minutes to repair the fault,
but an hour to diagnose it.
On a press line or in a weld cell the part swap is quick. The time goes into finding the fault: which input dropped out and why the interlock will not close. The answer is in the PLC program and the drawings, and on second shift the controls engineer who knows them has gone home.

§03 One platform
Everything your controls team knows, in one place.
Edmund reads the Allen-Bradley and Siemens programs, EPLAN and AutoCAD drawings, OEM manuals and years of maintenance logs, and answers from all of them at once.
/01 PLC · Allen-Bradley and Siemens
Reads the programs your controls team wrote.
Allen-Bradley, Siemens TIA Portal and Omron projects, plus anything that compiles to IEC 61131-3, in one searchable model. Edmund answers with the routine or block and the line, so a technician can follow code they did not write.

A tag resolves to the cabinet and the terminal a technician can put a hand on, on the press line or in the weld cell. Finding where a signal is wired takes seconds instead of a search through the drawing set.

-B34 is the light barrier receiver on conveyor 3. Its OSSD1 output runs on core 4 of cable -W34 to terminal -X9:4, then to input %I4.3 (A494/5.1). Terminal strip X9 is in +UH3.1.

§04 Where to start
Send us your hardest fault.
The one that took a whole shift to find, or keeps coming back on second shift. We diagnose it for free: describe it below, then pick a time for a 20-minute call.
What happens next
- 01You send the fault
A sentence or two about the fault, and your details.
- 02A 20-minute call
We agree which files we need. The 24 hours start when they arrive.
- 03The root cause, within 24 hours
Why the line stopped and where it sits in your Allen-Bradley or Siemens program and drawings, with the source for each step.
§05 Evidence
Results from plants that run Edmund.
“We use Edmund AI as an “invisible co-worker”: it fills the missing know-how, supports our technicians’ decisions, and speeds up finding and fixing faults.”
§06 Questions
What controls and maintenance leads ask first.
Does Edmund read Allen-Bradley programs?
Yes. Edmund parses Allen-Bradley, Siemens TIA Portal and Omron projects, plus anything that compiles to IEC 61131-3, into one searchable model. It answers with the routine or block and the line number.
What do we send for the hardest fault?
At first, the fault in a sentence or two and your details. On the call we agree which files matter, usually the PLC project or an export of it and the alarm log, and you hand them over. Missing pieces are fine: the answer says which sources it used.
Where does our data go?
Into Edmund on AWS, hosted in the EU (Ireland) or in the US, whichever you choose. It is encrypted and kept inside a single-tenant boundary for your company, and the language model runs under zero data retention, so nothing you send is kept for training.
Do we need to connect Edmund to the line?
Not for the first answer. It comes from the files you export. Live data from SQL or MES is connected later, if you want it, and Edmund only reads: nothing in your production systems gets changed.
Who is behind Edmund?
Edmund s.r.o., from Ostrava in the Czech Republic. It came out of an industrial consulting practice and today runs on 130+ machines across four countries.
