The MITSUBISHI Easysocket Driver is a software driver provided by Mitsubishi Electric for enabling communication between a computer running Windows and Mitsubishi PLCs (Programmable Logic Controllers) or other industrial devices via the "Easysocket" protocol. Easysocket is typically used for easy networking, allowing devices like PLCs to connect over Ethernet (TCP/IP) or other networks, allowing remote monitoring, control, and data exchange.

The driver allows you to communicate with Mitsubishi PLCs (such as the iQ-R, iQ-F, or older models) over Ethernet. The driver essentially facilitates the proper recognition and handling of the device over the network.
