FZ Vision System Platform

The ZFX-C15 is part of Omron's FZ series smart vision system platform, which combines intelligent cameras with a controller unit for industrial inspection applications. The FZ platform embodies the Touch, Connect & Go concept, allowing operators to set up inspections in three simple steps without specialized programming knowledge. The ZFX-C15 serves as the controller for a single FZ series camera, providing the processing power for image analysis, the display interface for setup and monitoring, and the I/O connections for integration with plant automation systems.

Single Camera Control Configuration

The ZFX-C15 is designed for single-camera applications, providing dedicated processing for one FZ series camera. This configuration is suitable for inspection stations where a single view is sufficient, such as part presence verification, label placement inspection, or dimensional measurement. The controller manages image acquisition from the connected camera, executes inspection algorithms, and generates output signals for downstream equipment. The single-camera design provides a cost-effective solution for applications that do not require multi-camera views.

PNP Output Configuration

The ZFX-C15 features PNP output circuitry, making it compatible with PLC systems and industrial automation equipment that use positive logic (sourcing outputs). PNP outputs are common in many industrial automation systems, particularly those originating from European and Asian manufacturers. The controller provides 23 output points including OR, ERROR, RUN, ENABLE, GATE, STGOUT0, STGOUT1, and DO0 through DO15. These outputs can be connected directly to PLC input modules, indicator lights, alarms, and other control devices. The PNP configuration provides a direct interface for integrating inspection results into production control logic.

Integrated Display and User Interface

The built-in 3.5-inch TFT color LCD provides live image display, inspection setup, and result visualization. The touch screen interface allows operators to draw inspection regions directly on the display, configure measurement parameters, and monitor inspection results. The display presents pass/fail status, measurement values, and error messages in a clear, easy-to-read format. The integrated display eliminates the need for an external monitor for basic setup and operation, simplifying installation and reducing system cost. The touch panel is designed for use with gloved hands, accommodating industrial operators.

Communication Interfaces

The ZFX-C15 provides multiple communication interfaces for integration with external systems. USB 2.0 (MINI-B connector, FULL SPEED) allows connection to a PC for advanced configuration and data logging. RS-232C serial communication (maximum 115,200 bps) enables connection to PLCs, HMIs, and other serial devices. RS-422 interface provides long-distance serial communication (also up to 115,200 bps), though it cannot be used simultaneously with the RS-232C port. Ethernet 100BASE-TX/10BASE-T supports network communication for centralized setup and remote monitoring. An analog RGB monitor output (VGA resolution 640 x 480) allows connection of an external display for larger-screen viewing of inspection images.

Inspection Functions

The ZFX-C15 offers a comprehensive library of inspection functions for industrial vision applications. Shape inspection includes pattern search, sensitive search, flexible search, and graphic search for identifying parts based on their appearance. Size inspection includes area measurement and labeling for verifying component dimensions. Edge inspection includes position detection, width measurement, count verification, and angle determination for measuring features and detecting defects. Brightness and color inspection includes brightness analysis and HUE detection for verifying color and contrast. Position correction includes 1-model search, 2-model search, position, area, and angle correction to compensate for part positioning variations. These functions can be combined to create complete inspection routines for a wide range of quality assurance tasks.

Memory and Data Storage

The ZFX-C15 includes memory for storing up to 32 registered banks and 32 setup items per bank. This allows the controller to store inspection programs for different product types, enabling quick changeover between production runs. The image memory function can store up to 100 images, providing a record of inspection results for quality tracking and process analysis. An SD card slot provides expandable storage for additional images and configuration backups. The analysis function includes a logging monitor for reviewing inspection history and identifying trends.

PLC Integration

The ZFX-C15 is designed for seamless integration with PLC systems through its parallel I/O interface and serial communication ports. The 12 input points (RESET, DSA, DI0 to DI8, TRIG) allow the PLC to trigger inspections, select inspection banks, and reset faults. The 23 output points provide inspection results, pass/fail status, and system status for PLC monitoring. The RS-232C and RS-422 serial ports support command-based communication, allowing the PLC to read detailed inspection data and change parameters. This comprehensive I/O capability allows the vision sensor controller to function as an integral part of the automation control system.

Environmental and Mechanical Specifications

The ZFX-C15 is designed for installation in industrial control environments with an IP20 protection rating (IEC60529). The controller operates in ambient temperatures from 0°C to 50°C and can be stored in temperatures from -15°C to 60°C. Humidity range is 35% to 85% non-condensing. The controller provides 20 MΩ insulation resistance (by 250 V megger) across all lead wires and the controller case, and dielectric strength of 1000 VAC, 50/60 Hz for 1 minute. Vibration resistance meets industrial standards at 10 to 150 Hz, 0.35 mm single amplitude, 50 m/s² acceleration. Shock resistance is 150 m/s² in X, Y, and Z directions. These specifications ensure reliable operation in typical manufacturing facilities.

Industrial Applications

The Omron ZFX-C15 vision sensor controller is deployed across numerous industrial inspection applications requiring single-camera vision. In automotive manufacturing, it verifies component presence, orientation, and part numbers. In electronics assembly, it inspects PCB component placement and solder joint quality. In food and beverage packaging, it verifies label placement, seal integrity, and fill levels. In pharmaceutical production, it inspects blister packs and verifies print quality. The controller's single-camera design is ideal for applications where a single view provides sufficient information for pass/fail judgment.

Conclusion

The Omron ZFX-C15 vision sensor controller provides PNP output, integrated display, and comprehensive inspection functions for single-camera industrial vision applications. With flexible communication interfaces and easy setup, it is a reliable solution for quality assurance and inspection tasks in manufacturing environments.
