A tape manufacturer has deployed multiple automated tape machines for coating, winding, cutting, and other processes. To enable real-time monitoring of equipment status and support precision maintenance, it is necessary to collect operating parameters and fault signals from each machine’s PLC (Programmable Logic Controller) and upload them to a central operations management platform. The main data collection requirements are as follows:

Collect data from the tape conveyor line’s protection devices to monitor abnormal conditions such as pull-cord activation, misalignment, underspeed, tearing, and chute plugging in real time.
Gather online vibration and temperature data from the drive motors to enable continuous condition monitoring and automatic alerting.
Leverage the plant’s existing full Wi-Fi coverage by using wireless networking to connect to the central operations management platform.
To address these needs, WideIOT provides a data collection solution centered around industrial PLC data acquisition gateways. By deploying a PLC data gateway inside each tape machine’s control cabinet, the solution interfaces with PLCs from Siemens, Mitsubishi, and other brands, parses and collects various machine operating parameters in real time, and transmits them via the plant’s Wi-Fi network to the central management platform. This enables round‑the‑clock remote monitoring, anomaly alerts, maintenance coordination, and energy efficiency analysis across the entire fleet of tape machines, effectively reducing unplanned downtime and improving Overall Equipment Effectiveness (OEE).

Key Capabilities

The PLC data gateway supports protocol parsing for major PLC brands including Siemens, Mitsubishi, Omron, and Delta. It can simultaneously collect parameters such as pull‑cord status, misalignment, underspeed, tearing, chute plugging, motor vibration and temperature, production time, and output count, meeting real‑time monitoring requirements.

Using the workshop’s Wi‑Fi network, the gateway transmits data to the operations management platform over encrypted wireless channels. This replaces the traditional manual method of reading values from control panels, eliminating data delays and transcription errors while also avoiding extra wear on control components caused by frequent cabinet access.

When abnormal conditions are detected—such as a sudden current spike in a motor, excessive temperature, or belt misalignment—the system can simultaneously notify managers via WeChat, SMS, email, and on‑site audible/visual alarms. Critical alerts are prioritized to help operators quickly pinpoint the root cause of faults and shorten Mean Time To Repair (MTTR).

With the platform’s built‑in visual dashboards, operators can generate tape machine performance reports by shift, day, week, or month. These reports cover metrics such as start/stop counts, load rates, energy consumption, and ranked fault frequencies. Managers can customize threshold rules and inspection schedules, enabling a shift from reactive "break‑fix" maintenance to proactive, preventive operations.
