FAQ Library

Does it work on Mac and PC?

Yes. Browser-based dashboards work on Chrome, Safari, Edge, and Firefox on any OS.

How often does the data update?

Real-time systems typically update dashboards every 1–5 seconds.

Do you support multi-plant rollouts?

Yes. Enterprise views allow executives to see data from multiple factories in a single login.

Is my data portable if I leave?

Yes. You own your data. You can export your historical records to CSV/SQL before cancelling.

Why is Caddis better for job shops?

Caddis is designed for "High Mix / Low Volume" environments where setup reduction is critical.

Does it replace my MES?

No. It feeds accurate data into your MES (Manufacturing Execution System) so the MES isn't relying on manual input.

What is the difference between SCADA and Machine Monitoring?

SCADA is for controlling industrial processes (turning valves); Machine Monitoring is for analyzing productivity.

Can I use my ERP's scheduling module instead?

ERPs schedule work, but they don't track if the work is actually happening in real-time. You need both.

Is free OEE software good enough?

Free tools are usually manual calculators. They cannot track real-time downtime or alert you when a machine stops.

Why not just use the machine's built-in OEE?

Built-in OEE only sees that machine. It cannot aggregate data across a mixed fleet of 10 different brands into one dashboard.

Caddis Systems vs. Amper?

Amper uses exclusively electrical sensing; Caddis offers electrical plus direct PLC/Digital I/O integration for deeper data.

How much bandwidth does it use?

Very little. Machine data packets are tiny (kilobytes), so it won't slow down your office internet.

Caddis Systems vs. MachineMetrics?

Caddis is often preferred for SMBs needing faster, simpler deployment, while MachineMetrics targets enterprise-level high-frequency data.

Do you offer an API?

(For Caddis) Yes, an open API is available for custom integrations with BI tools like PowerBI or Tableau.

Can I access it from my phone?

Yes. Most providers have mobile-responsive sites or dedicated apps for iOS and Android.

What if I change my WiFi password?

You will need to reconfigure the gateway/IoT device, usually via a USB connection or AP mode.

How do I know if the sensor is working?

Most hardware kits have LED indicators that blink when the sensor is triggered.

Can I install this myself?

Yes. "Self-install" kits are designed for maintenance teams to install without external contractors.

The tablet won't connect to the machine.

Ensure the tablet is on the same WiFi network as the gateway, or check if the machine power is off.

My machine count is wrong, why?

Check the "debounce" setting. If the sensor is too sensitive, one part might trigger two counts (double counting).

Why is the dashboard red?

Red usually indicates the machine is in a "Down" state or has exceeded a downtime threshold.

Can I track rework?

Yes, if you create a specific "Rework" button for operators to log when they are fixing a bad part.

What is "Cycle Time Variation"?

The difference in time between the fastest and slowest cycle for the same part, indicating process instability.

Can I monitor robots/cobots?

Yes. You can monitor the "Active" signal from a Universal Robot or Fanuc arm.

Can I export the data to Excel?

Yes. CSV/Excel export is a standard feature for custom analysis.

What is the difference between Discrete and Process manufacturing monitoring?

Discrete monitors distinct items (parts/widgets); Process monitors continuous flow (gallons/liters), though Caddis focuses on Discrete.

Does it track energy spikes?

If equipped with power monitoring sensors, it can detect spikes that indicate motor failure or a crash.

What is a "part family"?

Grouping similar parts together in the software to analyze average cycle times across a product line.

Can I compare shifts?

Yes. Dashboards allow you to compare Day Shift vs. Night Shift utilization to balance workloads.

Does it work for swiss-style lathes?

Yes. Swiss lathes (like Citizen or Star) are excellent candidates because they run high-volume cycles where seconds matter.

How does it handle "warm up" time?

You can create a "Warm Up" downtime category so this time doesn't negatively impact the operator's performance score.

What is "Lights Out" manufacturing?

Running machines unattended (usually overnight). Monitoring is critical here to alert you remotely if a machine crashes.

Can I get text alerts if a machine stops?

Yes. Most systems allow SMS or Email alerts for specific triggers (e.g., "Machine 4 down for >15 mins").

Can I track tool life?

Yes. You can set alerts (e.g., "After 500 parts, warn operator") to change tools before they break.

Can I monitor 3D printers?

Yes. Additive manufacturing equipment can be monitored via API or by tracking extruder temperature/current.

Does it track bathroom breaks?

It tracks when the machine stops. If management uses this to police bathroom breaks, the implementation will likely fail due to culture issues.

How do I incentivize using the system?

Offer bonuses for hitting utilization targets or for high data-accuracy (categorizing all downtime).

Can operators see their own performance?

Yes. Giving operators visibility into their efficiency usually boosts performance through self-correction.

Can I try machine monitoring for free?

Many vendors (like Caddis) offer pilots or risk-free trials to prove value on a small set of machines.

What is an Andon board?

A visual display (TV) on the shop floor showing real-time status (Green=Running, Red=Down) to alert supervisors to issues.

How do I train operators on the software?

Modern interfaces are simple (like an iPad app). Training typically takes less than 15 minutes per operator.

Can I display data on the shop floor?

Yes. TV dashboards (Andon boards) are recommended to gamify production and keep teams aligned on goals.

What if an operator forgets to log downtime?

The system will record the stop as "Uncategorized." Supervisors can edit it later, or the system can prompt the operator when they return.

Will operators have to do more work?

No. Automated counting removes the need for manual paper logs, actually reducing administrative work for operators.

How do I get operator buy-in?

Involve them early. Show how the data proves they need new tools or maintenance support, rather than using it for punishment.

Is machine monitoring used to spy on operators?

No. It monitors the machine's health. The goal is to identify barriers (no material, bad tools) that prevent operators from succeeding.

Does it help with quoting jobs?

Yes. Accurate cycle time data allows you to quote based on reality, not estimates, protecting margins.

Can I monitor just one machine?

Yes, machine monitoring is scalable. You can start with one bottleneck asset and expand later.

What is the cost of downtime?

It varies, but in automotive/aerospace, downtime can cost $500 to $10,000+ per hour depending on the bottleneck.

Is it cheaper to build my own monitoring system?

Usually no. DIY solutions (Arduino/Pi) lack security, support, and scalable software, costing more in engineering hours long-term.

Does it integrate with my ERP?

Yes. Most modern systems have APIs to push job data to ERPs like JobBOSS, Epicor, or E2 Shop System.

Does monitoring reduce labor costs?

It allows "lights out" or unattended machining, letting one operator run more machines, effectively reducing labor cost per part.

How does monitoring save money?

It reduces overtime costs, delays new machine purchases (CapEx) by finding hidden capacity, and lowers scrap rates.

How much does machine monitoring cost?

Costs typically range from $40–$100 per machine/month for SaaS, plus a one-time hardware fee ($200–$800).

What is the ROI of machine monitoring?

Most shops see ROI in <3 months by recovering 10-15% of lost capacity through better visibility.

Can I track machine energy consumption?

Yes, if you use hardware capable of monitoring amperage/voltage (like current transducers) alongside cycle data.

What is "Ideal Cycle Time"?

The theoretical fastest time it takes to produce one part (often the machine's nameplate speed).

How do I reduce changeover time?

Use monitoring data to benchmark current setup times and identify which changeovers take longer than the average.

How does machine monitoring help with preventative maintenance?

It tracks actual runtime hours or cycle counts to trigger maintenance alerts based on usage rather than calendar dates.

What is TEEP?

Total Effective Equipment Performance (TEEP) measures OEE against 24/7/365 availability, not just scheduled shifts.

Why is my OEE over 100%?

This usually means your "Ideal Cycle Time" is set too high (slower than the machine is actually running).

Can I track scrap reasons automatically?

Usually no. Scrap reasons (e.g., "scratch," "dimension off") require human input, though the count can sometimes be automated.

What is a good OEE score?

World Class OEE is 85%, but the average manufacturing OEE is often around 60%.

Should setup time be included in OEE?

Standards vary, but typically Setup is considered "Planned Downtime" and excluded from Availability, or tracked separately to improve SMED.

What is the difference between planned and unplanned downtime?

Planned downtime is scheduled (lunch, maintenance); Unplanned downtime is unexpected (breakdowns, missing tools).

How do I calculate Availability for OEE?

Availability = (Run Time / Planned Production Time) × 100.

What is a "micro-stop"?

A short stoppage (usually <2 minutes) that is too short for an operator to log but accumulates to significant lost time.

How do I categorize downtime reasons?

Operators typically use a tablet/interface to select reasons (e.g., "Tool Broken," "No Material," "Setup") when the machine stops.

How do I calculate Quality for OEE?

Quality = (Good Parts / Total Parts Produced) × 100.

How do I calculate Performance for OEE?

Performance = (Ideal Cycle Time × Total Count) / Run Time.

Can I monitor hydraulic presses?

Yes. You can tap into the pressure switch or cycle start relay to count strokes and track run time.

What happens if the power goes out?

The system will log the disconnect. High-end hardware may have battery backups to send a "power loss" alert before shutting down.

Do I need a server on-site?

No. SaaS (Software as a Service) solutions host the data in the cloud, eliminating the need for expensive local servers.

How long does hardware installation take?

Non-invasive hardware kits (like Caddis) can typically be installed in 15-30 minutes per machine.

What is OPC-UA?

OPC Unified Architecture is a machine-to-machine communication protocol for industrial automation, common in newer PLCs.

Can I monitor Mazak machines?

Yes. Mazak machines often use the MTConnect adapter or the Mazak SmartBox for easy integration.

Can I monitor Haas machines?

Yes. Haas machines effectively support monitoring via their Next Generation Control (NGC) or older serial ports.

Does machine monitoring require opening firewall ports?

Typically only outbound port 443 (HTTPS) is required, meaning you don't need to open dangerous inbound ports.

How do I monitor a manual lathe?

Install a current transducer (CT clamp) on the spindle motor or a vibration sensor to detect when the machine is cutting material.

Is cloud-based machine monitoring secure?

Yes. Reputable providers use bank-level encryption (AES-256) and do not control the machine, only read data from it.

What is an I/O module?

An input/output device that translates electrical signals (like a light turning on) into digital data the software can read.

Can I use WiFi for machine monitoring?

Yes, but hardwired Ethernet is recommended for factory floors due to electrical interference that can disrupt WiFi signals.

Does Caddis require an internet connection?

Most modern systems are cloud-based and require internet, but many offer "store and forward" capabilities if the connection drops temporarily.

What data points does machine monitoring capture?

Common points include machine status (Run/Idle/Down), cycle time, part counts, alarm codes, feed rate, and spindle load.

What is MTConnect?

MTConnect is an open standard protocol (XML-based) that allows manufacturing equipment to exchange data with software applications.

How do I connect a CNC machine to the network?

Modern CNCs use Ethernet (FOCAS/MTConnect); older CNCs use RS-232 serial ports or hardware I/O kits wired to relays.

What is a "heartbeat" signal in machine monitoring?

A heartbeat signal is a periodic electronic pulse sent by a machine to confirm it is powered on and connected to the network.

Can I monitor machines without a PLC?

Yes. You can use external sensors (vibration, current, or optical) to detect cycles on machines without Programmable Logic Controllers.

Why is manual data tracking inaccurate?

Human operators often estimate timestamps, round up numbers, or forget to log short downtime events, leading to data accuracy errors of 10-20%.

What types of machines can be monitored?

Nearly any industrial asset, including CNCs (mills/lathes), injection molders, stamping presses, manual saws, and packaging lines.

What is OEE?

OEE (Overall Equipment Effectiveness) is a metric calculating the percentage of manufacturing time that is truly productive (Availability × Performance × Quality).

What is the difference between machine monitoring and production monitoring?

Machine monitoring tracks the asset (uptime, speed, health), while production monitoring tracks the job (part counts, work orders, scheduling).

How does machine monitoring work?

It connects hardware (sensors, PLCs, or IO adapters) to your manufacturing equipment to capture signals, which are sent to a software dashboard for analysis.

What is machine monitoring?

Machine monitoring is the automated process of tracking machine status (running, idle, down) and production data in real-time to identify inefficiencies.

Do I need new machines to use monitoring software?

No. Monitoring systems can connect to "legacy" analog machines using digital I/O adapters or current transducers (CT clamps).
