// Important first
We do not publish specific diagnostic steps.
Error codes are context-dependent. What is the right response on a CTX 400 with EPL2 would cause a second failure on a GDM with Eltropilot. Instead of a half-truth guide we give only the component class here — the real diagnosis we do by phone, in 5–10 minutes, free of charge and without promises.

the broad picture.

// Affected machines
Where the code appears.
CTX 200, CTX 310, CTX 400, CTX 510, CTX 600 — all CTX models with a Heidenhain control. Older CT machines with EPL/EP are affected too.
What the code means specifically on your machine depends on the year of manufacture, the control, the constellation and any previous maintenance. From 30 years of workshop experience we know the typical patterns — and we classify them by phone.
Please note first
What you should not do yourself.
Depending on the constellation, PLC 200 codes can be harmless (a sensor malfunction) or critical (tool turret bearing wear). A wrong diagnosis leads to consequential damage on the turret or to an unnecessary component replacement.
In concrete terms: before any repair on a Gildemeister CNC, back up the parameters and NC programs. Replace components only after a diagnosis, never on suspicion. If in doubt: call us. Those 5 minutes often save a four-figure mis-investment.
// What you can do now
Narrow down PLC 200
on the phone.
In 5–10 minutes we clarify with you by phone what is really going on with your Gildemeister machine. Free of charge. No sales pressure. We know the code from workshop practice — no algorithm, no bot.

// FREQUENTLY ASKED QUESTIONS
What does PLC 200 mean on a Gildemeister?
A plain-text message from the PLC logic of the Heidenhain control. It often appears during tool turret operations or clamping device switching.
Which Gildemeister machines are affected?
CTX 200, CTX 310, CTX 400, CTX 510, CTX 600 — all CTX models with a Heidenhain control. Older CT machines with EPL/EP are affected too.
What is usually behind it?
From 30 years of workshop practice: mostly the tool carrier / tool turret mechanics or the switching hydraulics. An exact diagnosis needs a machine-specific workshop check or a preliminary phone diagnosis with ESDI.
What should I not do myself?
Depending on the constellation, PLC 200 codes can be harmless (a sensor malfunction) or critical (tool turret bearing wear). A wrong diagnosis leads to consequential damage on the turret or to an unnecessary component replacement.
