Is Fanuc FOCAS actually reliable?

Very. We use FOCAS directly from a Delphi connector, with our own wrapper for reconnection, keep-alives and error handling. A typical connector hasn't crashed in months.

What about Siemens 828D without an HMI PC?

Supported via direct Snap7/S7 PLC reads. You don't need the HMI PC, but you do need network access to the PLC — which typically means a switch and a static IP.

Can we write our own connector?

Yes. xynLog accepts data over REST (JSON) and MTConnect, so you can build a connector in any language. We've seen customers ship custom connectors for in-house PLCs in a few days.

08/08 · MACHINE CONNECTORS

Native protocols for every major CNC controller. Not MTConnect-only.

We built the machine connectors ourselves — in native protocol, not screen-scraped, not reduced to MTConnect subsets. Heidenhain, Fanuc, Siemens, Haas, DMG Mori, Mitsubishi, Mazak, Okuma and more — plus OPC-UA / MTConnect for anything else on your floor.

MTConnect-only monitoring is a lowest-common-denominator compromise.

Many monitoring vendors ship a single MTConnect connector and call it done. But not every controller speaks MTConnect, and those that do only expose a fraction of what's actually inside the machine. xynLog ships native connectors for every major CNC brand, plus OPC-UA and MTConnect for the rest — so you get spindle load, tool life, alarm codes and program context, not just a running/idle flag.

Every brand, natively

Heidenhain iTNC 530 / TNC7

Native Heidenhain protocol. Program, program status, alarms, spindle, feed, tool data, override settings, axis positions — the full set.

Fanuc 16i / 18i / 21i / 30i / 31i / 32i

FOCAS direct reads. Status, execution mode, cycle count, alarms, tool data, spindle load, axis feed, program lookup.

Siemens Sinumerik 828D / 840D sl

Snap7 / S7 protocol for direct PLC reads, plus program and mode parsing. Works against the standard HMI PC.

Haas

Native TCP socket protocol. Status, program, part count, alarms and overrides. No MDC module required.

DMG Mori

MTConnect for MSX, proprietary TCP for Celos/ERGOline. Two connectors in one, switched per machine.

Mitsubishi

EZNCAUT COM library. Status, program, alarms and spindle on M700/M800/NC Explorer-era controls.

How a connector is deployed

/ 3 STEPS

Pick the brand
Each brand has its own Windows-based connector, built in Delphi for deterministic behaviour. We ship them as part of xynLog — no extra licences.
Connect to the controller
Ethernet in most cases, serial for legacy controls. The connector runs on a small box next to the machine or on a shared edge PC for a cell.
Signals flow into xynLog
Status, alarms, counters, tools and program context flow into xynLog in real time. The same data appears in OEE, predictive maintenance and the mobile app.

Frequently asked questions

Yes. Our Heidenhain connector works with iTNC 530, TNC 620, TNC 640 and TNC7 — we've deployed against all of them. Probe signals and tool tables are supported in addition to the basic status set.
