Description

The CMPTCTU functions as a high-speed counter module, engineered to track digital events (such as pulses from encoders or proximity sensors) and convert them into actionable data for industrial control systems. It supports both up-counting (incrementing) and down-counting (decrementing) modes, with a maximum counting frequency of 100kHz—capable of tracking 6 million events per minute, making it suitable for high-speed applications like bottling lines. What sets it apart is its advanced noise filtering, which ignores spurious pulses caused by electromagnetic interference (EMI) from nearby motors or welders, a common issue that plagues basic counters.

CMPT CTU

The CMPTCTU integrates seamlessly with control systems via Modbus RTU and Ethernet/IP, allowing remote monitoring of counts, preset adjustments, and reset commands. It includes two configurable outputs (relay or transistor) that trigger alarms or machine actions when counts reach user-defined presets—for example, stopping a conveyor when a production batch is complete. Housed in a rugged plastic casing with an IP20 rating, the module is designed for DIN rail mounting in control cabinets, with a wide operating temperature range ensuring reliability in harsh factory environments.

CMPT CTU

Main features and advantages:

Choosing theCMPTCTUdelivers tangible benefits for industrial counting applications. Its high-speed counting capability (100kHz) ensures no events are missed in fast-moving processes—for example, accurately tracking 500 bottles per minute on a filling line, whereas a slower counter might undercount by 5-10% during peak speeds. The advanced noise filtering reduces false counts caused by EMI, a critical advantage in automotive plants with robotic welders, where electrical noise can disrupt basic counters. Engineers will appreciate the flexible communication options, which allow the module to integrate with both legacy PLCs (via Modbus RTU) and modern IoT-enabled systems (via Ethernet/IP), eliminating the need for protocol converters. The dual configurable outputs simplify process automation, enabling direct control of alarms or machinery without additional relays—reducing hardware costs and cabinet space. Most importantly, the CMPT CTU’s 32-bit counting range eliminates the need for manual resets in long-running processes, such as tracking monthly production totals, reducing administrative overhead and human error.

Application areas:

The CMPTCTU excels in diverse industrial scenarios where accurate event tracking is key. In food packaging facilities, it counts sealed packages as they exit a machine, triggering a conveyor stop when a case reaches 50 units and sending data to an HMI for real-time inventory updates. In metal fabrication, it tracks the number of punches a press makes, alerting maintenance teams when the tool approaches its wear limit (e.g., 100,000 cycles) to prevent defective parts. The module also performs reliably in logistics, where it counts pallets entering a warehouse via a conveyor, integrating with a WMS (Warehouse Management System) to update stock levels automatically. In each application, the CMPTCTU provides the accurate, reliable counting needed to maintain production schedules, quality standards, and inventory accuracy.

Installation and maintenance:

Before installing the CMPT CTU, verify that the power supply is within the 18-30V DC range and that the mounting DIN rail is securely fastened to prevent vibration-induced connections. For sensor wiring, use twisted-pair shielded cables and ground the shield at both ends to maximize noise filtering effectiveness.

During setup, configure the counting mode (up/down), filter settings (based on sensor type), and preset values via the web interface or TIA Portal—for high-speed applications, set the filter to 10µs to avoid missing fast pulses. Test the module with a known number of events (e.g., manually triggering a proximity sensor 100 times) to verify accuracy before full deployment. In maintenance routines, inspect input/output connections quarterly for corrosion, especially in humid environments, and clean the module’s ventilation slots to prevent overheating. Periodically verify the noise filter settings, as changes in machinery layout (e.g., adding a motor near the sensor) can increase EMI levels over time.
