Product Details

The ProSoft PLX51-DLplus-232 is an upgraded DIN-rail mounted industrial data logger, evolved from the standard PLX51-DL-232, designed for remote automation sites with unstable or limited network connectivity. It supports multi-protocol data acquisition including EtherNet/IP, DF1 serial, Modbus RTU and Modbus TCP, which can collect data from Rockwell Logix PLC, legacy DF1 controllers, Modbus transmitters, power meters and variable frequency drives without relying on a local historian server or industrial PC. The solid-state non-volatile memory can hold more than 16 million timestamped data records, each record carries 50ms high-precision timestamp, tag name, data type and process value, supporting full traceability of production events and fault playback. Users can choose circular overwrite mode or stop-logging mode when memory reaches full capacity to match different on-site management requirements. Compared with the basic version, this enhanced logger adds a built-in web server supporting real-time trend display for up to five custom variables, allowing engineers to check process curves directly on browsers without configuration software. It supports REST API for automatic JSON data transmission to upper MES, SCADA or cloud platforms, and historical records can be exported as CSV files via web page or PLX50 Configuration Utility for offline report analysis and predictive maintenance. It also retains DF1 packet capture function to simplify serial DF1 communication troubleshooting. The logger works independently of the host PLC scan cycle, so data recording and data uploading will not consume PLC resources or interfere with normal production control logic. It provides complete diagnostic information including communication status, record quantity, storage usage and fault flags, accessible through web interface or configuration tool. A conformal coated version is optional for humid, dusty and corrosive industrial environments. This model is widely used in remote pumping stations, oil and gas skids, mobile machinery, water treatment and manufacturing process monitoring projects.

This logger adopts compact IP20 plastic housing for DIN rail installation. It is equipped with one 10/100Mbps RJ45 Ethernet port and one 2.5kV isolated RS232 terminal port, accepts 10VDC to 28VDC power supply with typical power consumption of 1.7W. LED indicators display power status, module activity, Ethernet link and serial communication status for convenient on-site inspection. The operating temperature range is -20°C to 70°C, storage temperature ranges from -40°C to 80°C, relative humidity 5% to 95% non-condensing. It complies with IEC EMC standards and has obtained UL/cUL Class 1 Div 2 and CE certifications. It supports remote configuration, firmware upgrade and configuration backup for long-term field maintenance.

This enhanced multi-protocol industrial data logger is widely applied in unmanned remote stations, mobile drilling equipment, wastewater treatment monitoring, packaging machinery data recording and skid-mounted equipment condition tracking projects. It caches key process data locally during network disconnection and resumes uploading automatically after communication recovery, effectively preventing loss of critical production data. As a reliable standalone enhanced data recording spare part, the PLX51-DLplus-232 keeps original control devices and wiring unchanged and effectively reduces the investment cost of remote data acquisition and visualization system.
