Application Notes
Real-world examples of how our IoT gateway solutions empower industries with seamless monitoring and automation using industrial IoT gateway technology.
Heavy Machinery Condition Monitoring
Reliable monitoring for construction, mining, and industrial equipment
Customer Problem
Heavy machinery such as excavators, loaders, and pumps operate in extreme environments that expose mechanical, electrical, and hydraulic components to severe stress. Unexpected breakdowns result in project delays, high maintenance costs, and productivity loss. Manual inspections are reactive and rarely detect failures early enough to prevent downtime.
Our Solution
The emNet 4G Gateway connects directly to machine controllers via RS485 Modbus, continuously transmitting parameters such as fuel levels, motor RPM, hydraulic pressure, temperature, and fault codes. Real-time dashboards and instant alerts allow site supervisors to respond proactively, minimising breakdowns and keeping equipment running at maximum efficiency.
Material Handling Condition Monitoring
Smarter, safer, and more efficient monitoring for automated handling systems
Customer Problem
Material handling operations depend on motors, drives, and sensors to keep production moving. Failures—like conveyor jams, overloads, or drive faults—can stop entire lines, cause safety hazards, and result in costly downtime. On-site alarms provide limited information and no early indication of underlying failure patterns.
Our Solution
The emNet 4G Gateway links directly to VFDs and controllers over RS485, capturing live data including power, current, voltage, motor health, and system faults. This information is securely delivered to the cloud, where maintenance teams can detect anomalies, analyze performance trends, and take corrective action before failures occur.
Remote / Standoff Tuning & Calibration
Bluetooth diagnostics for safer, faster, and more efficient machine calibration
Customer Problem
Technicians often need to physically access control panels or enter restricted areas to calibrate equipment. This exposes them to electrical hazards, awkward working positions, and time-consuming procedures—sometimes even requiring ladders or shutdowns. The process increases risk, delays production, and raises maintenance costs.
Our Solution
Grab BT eliminates physical access requirements by enabling tuning and diagnostics over Bluetooth. Engineers can connect wirelessly to RS485 machines, view parameters, and make adjustments using a mobile phone or tablet from a safe distance. Live readings and error logs enable precise calibration without disrupting production or exposing technicians to risky environments.
Mirroring Machine Screen / Nearby Control (Door Controller)
Monitor and control machine displays without being tethered to the main panel
Customer Problem
Operators waste time walking between the machine display and work area just to check parameters or make small adjustments. In many cases, the control panel is mounted in hard-to-access or unsafe points. This decreases productivity and increases fatigue and safety risks when operators must move frequently around the machine.
Our Solution
Using Grab BT, machine RS485 display data can be mirrored to a phone or tablet. Operators can check readings, reset errors, and make adjustments without opening panels or moving away from their work area. For door controllers and RCF systems, this enables nearby, safe control—improving efficiency and reducing operational fatigue.
Water Management & Treatment Systems
Smart SMS-based monitoring for pumps, tanks, and utility systems
Customer Problem
Housing societies and utilities often struggle with issues like tank overflow, pump dry runs, or low-pressure conditions. Full SCADA systems are expensive and unnecessary for smaller facilities. Without timely alerts, small faults escalate into water wastage, pump damage, and customer complaints.
Our Solution
The emSMS Gateway provides a cost-effective monitoring and alerting solution with 2 digital inputs and 1 relay output. It detects pump faults, tank level issues, and dry-run conditions, and instantly sends SMS alerts to up to 10 registered numbers. Operators can also trigger remote ON/OFF commands via SMS—eliminating the need for physical site visits.
PLC Fault, Downtime & Utility Alert Notifications
Instant SMS alerts for industrial faults, failures, and unplanned shutdowns
Customer Problem
When PLCs or essential utilities such as power, compressed air, or water supply fail, operations can come to a halt within seconds, leading to major production losses. In many facilities, operators only discover the issue after visible symptoms appear on the shop floor—by which time downtime has already escalated, recovery becomes expensive, and service-level commitments are affected.
Our Solution
The smsAlert Gateway connects directly to PLC fault relays or utility alarm outputs through digital inputs. The moment a fault occurs—such as breaker trips, compressor shutdowns, motor overloads, or water line failures—it automatically sends SMS alerts to supervisors, engineers, and maintenance teams. With support for up to 10 recipients and a 50-event alert log, smsAlert ensures complete visibility of critical failures, enabling faster response, reduced downtime, and improved operational reliability.
