The CP2E is a micro PLC for data collection and machine-to-machine communication. It offers improved connectivity for Ethernet and serial devices. Two built-in Ethernet ports eliminate the need for switching hubs. The four-axis positioning function with linear interpolation allows fast positioning and reduces machine cycle time. The PID with autotuning function enables stable temperature control, reducing startup time. The controllers can recover from electrical interference automatically, therefore increasing machine efficiency and avoiding CPU stops.
