Each record includes a date and time stamp, and up to 450,000 records can be stored and downloaded.
 
With connection to the same local network, real-time data can be accessed anytime and anywhere using the free Windows software, iOS app, or the Android app.
 
The CL-220 Series supports widely used industrial communication protocols such as DCON, Modbus RTU, and Modbus TCP. For Ethernet connectivity, it also supports MQTT, a modern machine-to-machine (M2M) and  Internet of Things(IoT) communication protocol. It features multiple communication interfaces, including RS-485, Ethernet, PoE and Wi-Fi, allowing easy integration into existing HMI or SCADA systems, and ensuring simple maintenance in distributed control environments.
