Memex MERLIN Alternatives: CNC Monitoring and OEE Options Compared

A contract machining plant has run MERLIN for years on its Fanuc-controlled lathes and mills. Now it adds a welding cell and an assembly area, and the new operations director wants one OEE figure for the whole site, with the cost of each loss. Does MERLIN stretch, or is it time to compare?

This page covers what Memex's own site says MERLIN does, the signs that it still suits you, and five tools to compare by job. Fabrico is one of the five, and Fabrico wrote the page, so there is no ranking. If you are unsure whether the plant needs monitoring or a MES, read MES vs machine monitoring first.

What Memex MERLIN is (as of 12.11.2026, per Memex's site)

Memex Inc. is based in Burlington, Ontario. Its homepage calls Memex the developer of MERLIN, an IIoT platform, and lists manufacturing operations management systems and machine monitoring solutions. The older memex.ca address redirects to memexoee.com. Its product pages, read on 12.11.2026, describe:

• MERLIN Tempus. The Tempus page says Tempus is Latin for time and that the software measures and analyzes manufacturing time, with machine states tracked automatically and web dashboards for operators through to senior management.
• Connection. MTConnect, Fanuc FOCAS, Fanuc I/O link to MTConnect and OPC. For older machines, the homepage names hardware connector adapters, such as the Ax760 MTConnect adapter for Fanuc controls with I/O link.
• Operators. The MERLIN Operator Portal is a Windows touch-screen HMI that prompts operators for down-time reasons, classifies part rejects and counts, and is barcode ready.
• Money. MERLIN Financial OEE shows the hourly profit rate of each product on each machine. Memex says Robert C. Hansen guided its development.
• ERP. Its ERP data collection page lists three integration methods, direct integrations to Epicor and Syteline, and labor and time tickets sent back to the ERP.
• Setup. Tempus can operate independently of the corporate network, has open APIs, a shift scheduler and email alerts for chosen machine events. Memex also sells DNC and memory upgrades for older controls.

We leave out the productivity and payback figures on Memex's homepage, as they are vendor-reported.

Ask Memex: which modules sit on Tempus and which need Tempus Enterprise Edition, and how a welder or assembly station reports.

Signs MERLIN still suits you

Stay with MERLIN, or keep it in the comparison, when most of these hold:

• Most machines are CNC, many with Fanuc controls, and direct control data matters.
• You want operator reasons on a touch screen at the machine, with barcodes for orders.
• Profit per machine and product is the question the board asks.
• The system should work apart from the corporate network, and DNC or memory upgrades are on the same list.

If you are adding welding, assembly or manual stations, or want the software hosted in the cloud, test the options below on those stations first.

Running, stopped, and what it cost

Every tool here can tell when a machine runs. They differ on who names the cause of a stop, and on whether lost time gets a money value. MERLIN does both through the Operator Portal and Financial OEE. The alternatives split the same way.

A money view only works if the minutes under it are right. Before you compare money screens, check that each tool assigns the same lost minutes to the same causes on one real shift.

Fabrico: one OEE figure for CNC, welding and assembly

Fabrico wrote this page. Fabrico is a cloud platform for OEE and light MES. Like MERLIN, it gets machine states from the machine and the stop reason from the operator, and it puts a money value on lost time. The difference is scope: it is built for plants where CNC machines share a floor with presses, welders and manual assembly. From our MES and OEE overview:

• Three routes for data. A connection to the PLC or controller; a Fabrico IoT device with external sensors for a welder or an older lathe; or the camera add-on, with AI cameras, where a station gives no usable signal. Supported protocols include OPC UA, Modbus, PROFINET, MQTT and EtherNet/IP (machine connectivity).
• Reasons on a tablet or phone. The machine signal records when a stop started and how long it lasted; the operator picks the cause from the plant's reason list on a tablet or phone.
• Losses priced live. Availability, performance and quality per line and shift, with losses shown in money, on web, iOS and Android.
• The camera add-on counts output at an assembly bench or any other station with no usable signal. Its video can be opened for any moment on the shift timeline; in the standard setup the camera add-on's video is streamed on request, not stored in Fabrico (camera add-on details).
• Repairs on the same record. A technician can open a work order straight from a stop.
• Integration. REST API, webhooks, and Excel or CSV export; a link to SAP or another ERP is scoped per customer.
• Timing. Devices connected in about a month; full rollout in 3 to 4 months.
• Left to the ERP: job dispatching, BOMs and routings. On the roadmap, not live: production planning and scheduling, and a camera add-on that detects stops and suggests a likely reason.

Ask us in the demo: what export you would need from MERLIN to keep past OEE for comparison, and how a welder with no controller reports.

Datanomix: CNC job scores from program data

Datanomix, of Nashua, New Hampshire, markets Data-Powered Production to CNC shops, from high-mix job shops to high-volume OEMs. Read on 12.11.2026, its pages describe:

• Part number and job tracking straight from the machine, with cycle times, part counts, setup and changeover detection, downtime and OEE.
• No operator reason codes: its production monitoring FAQ says G-code analytics determine what caused a stoppage and how long it should last.
• A benchmark and a production score per job after a few parts, shown on TVs on the shop floor.
• Part-level profitability analysis, G-Code Cloud with integrated DNC, and coaching from manufacturing people.

Compared with MERLIN: both read CNC controls, both add DNC and both put money on output. The fork is the stop cause: Datanomix derives it from the program, MERLIN asks the operator through the Operator Portal.

Fits shops that want standards set per job from program data and no data entry at the machine.

MachineMetrics: a hosted operations system for discrete plants

MachineMetrics presents MaximaOS as an AI-powered manufacturing operations system for discrete manufacturing. Its homepage, read on 12.11.2026, says:

• Stoppages of any duration are captured, categorized from machine signals and ranked by cost.
• Availability, performance and quality are derived from machine data against real schedules.
• Work orders, scheduling, labor, quality and tooling share one data model, and Max AI answers questions in plain language.
• There is nothing to host; machines of every generation connect, with open APIs, under ISO 27001 certification.

Compared with MERLIN: both price lost time and talk to the ERP. MachineMetrics' pages describe a hosted next-gen MES with scheduling; MERLIN's describe modules that can run apart from the corporate network. More in our MachineMetrics alternatives.

Fits shops that want monitoring, scheduling and work orders on a platform they do not host.

Scytec DataXchange: on your servers or in the cloud

Scytec's site offers DataXchange in two forms, cloud and on-premise, as an OEE and machine monitoring system, and says it draws on 25 years of data collection software work. Scytec is now owned by Minitab, per its acquisition news. Read on 12.11.2026:

• Dashboards update utilization, downtime and OEE in real time, with apps for desktop PCs, tablets and smartphones.
• For machines without Ethernet and for manual machines, a Status Relay Controller collects data with no programming, and also takes sensor inputs such as current and fill level.
• Minitab's announcement groups DataXchange with its SPC and digital twin solutions.

Compared with MERLIN: both read CNC controls, sell hardware for older machines and can run on site. DataXchange's pages add a cloud option and list fabrication equipment such as saws and welders; MERLIN's add Financial OEE and DNC.

Fits shops that want the choice between their own servers and a hosted system, close to Minitab's quality tools.

FactoryWiz: machine monitoring with DNC

FactoryWiz describes itself as machine monitoring and DNC software, and its site says it is powered by Celsus Software, with a head office in Corvallis, Oregon. As of 12.11.2026:

• It tracks machine performance, downtime, OEE and production data, and handles CNC file transfers.
• It sends automated daily, weekly and monthly OEE reports, plus email and text alerts for alarms, part counts and machine conditions.
• It connects modern machines over Fanuc FOCAS, MTConnect, OPC-UA and umati, and collects data from older equipment without native Ethernet.
• Customers own and control their data, with the option to store everything locally.

Compared with MERLIN: both pair monitoring with DNC and can keep data on site. FactoryWiz's pages lead with reports and alerts; MERLIN's add an operator portal and Financial OEE.

Fits shops that want monitoring and DNC together, with production data kept on their own systems.

Which MERLIN alternative fits your shop

• Operator reasons on a touch screen, a profit rate per machine, DNC and on-site running: MERLIN.
• Job scores from CNC program data, with no operator entry: Datanomix.
• Monitoring, scheduling and work orders, hosted for you: MachineMetrics.
• Your own servers or the cloud, beside Minitab's quality tools: Scytec DataXchange.
• Monitoring with DNC and scheduled OEE reports, data kept locally: FactoryWiz.
• One OEE figure with priced losses across CNC, welding and assembly: Fabrico.

Some plants keep MERLIN on the CNC cell and add a plant-wide OEE layer. That works if one system is named as the owner of the OEE figure; light MES vs full MES explains where the line usually sits.

Worked example: OEE and money on one lathe

Illustrative numbers for a CNC lathe over one 8 hour shift; this is sample data, not a customer or a product screen. A 30 minute break leaves 450 planned minutes, and the ideal cycle is 3.0 minutes a part.

Stops took 54 minutes, so run time was 396 minutes and availability 88.0%. In 396 minutes the ideal is 132 parts. The lathe made 120, so performance is 90.9%.

Three parts were scrapped, leaving 117 good: quality is 97.5%. OEE is 88.0% x 90.9% x 97.5% = 78.0%, the same as 117 good parts x 3.0 minutes over 450 minutes.

The 99 minutes that made no good parts are 54 of stops, 36 of slow running and 9 of scrap. At a sample value of EUR 90 a machine hour, they are worth EUR 148.50 this shift. A money view such as MERLIN's Financial OEE or Fabrico's losses in money starts from the same minutes, so ask each vendor how it sets the hourly value. The formula is in our OEE calculation guide, and micro-stops covers the short stops that rarely reach a paper log.

Questions to ask any vendor on this list

Use one CNC cell and one welding or assembly station as the test, and ask every vendor, Fabrico too:

• Connection per machine? FOCAS, MTConnect, OPC, an adapter or a sensor, and what happens on a welder with no port.
• Who names the stop? Operator, program, signal, or a mix.
• The OEE maths? Source of the ideal cycle, treatment of changeovers, and scrap entry.
• How is lost time valued? Which hourly figure, from whom, and per machine or per product.
• Where does the software run? Your servers, the vendor's cloud, or both, and who maintains it.
• What happens to your MERLIN history? Export format and how far back it goes.

What people ask next

Is Memex MERLIN still sold?

Yes. As of 12.11.2026, Memex's own site, memexoee.com, lists MERLIN Tempus, the Operator Portal, Financial OEE, ERP data collection and connectivity hardware, with appointments and webinars on offer. The older memex.ca address redirects there.

What is MERLIN Tempus?

The software base of Memex's MERLIN platform. Its page says Tempus measures and analyzes manufacturing time, tracks machine states and processes, and shows web dashboards. It supports MTConnect, Fanuc FOCAS, Fanuc I/O link to MTConnect and OPC.

What is Financial OEE in MERLIN?

A MERLIN module that links OEE to profit. Memex says it gives the hourly profit rate of each product on each machine and that Robert C. Hansen, an author on OEE and Financial OEE, guided its development. It builds on data collected by MERLIN Tempus Enterprise Edition.

Which MERLIN alternatives work on older CNC machines?

Datanomix mentions an amp clamp for older machines, Scytec offers its Status Relay Controller, FactoryWiz says it connects equipment never equipped with native Ethernet, and Fabrico adds its own IoT device with external sensors to machines without a usable controller.

Which alternatives can run on premises?

MERLIN Tempus can operate independently of the corporate network, per its page. Scytec DataXchange is offered in the cloud or on premises, and FactoryWiz gives the option to store everything locally. Fabrico is a cloud platform; EU customers are hosted on AWS in Frankfurt.

How is Fabrico different from MERLIN?

Both take machine states from the machine and reasons from the operator, and both put a money value on lost time. MERLIN is a modular CNC monitoring suite with DNC and memory upgrades. Fabrico is a cloud OEE and light MES platform for mixed floors, with a camera add-on for stations with no signal and maintenance on the same machine record.
