What type of network is created when a PLC is connected to a computer using a single cable?

When a PLC (Programmable Logic Controller) is connected to a computer using a single cable, the type of network that is created is known as a point-to-point network. This configuration involves a direct connection between two devices, allowing them to communicate with each other without the need for additional devices or connections.

In a point-to-point network, the communication is typically straightforward and focused; it allows for dedicated bandwidth between the two connected devices. This is particularly beneficial for applications that require reliable and direct communication, such as when monitoring or controlling a PLC from a computer.

While local area networks, Ethernet networks, and wireless networks involve multiple devices and often more complex communication protocols, a point-to-point network simplifies the connection to just two endpoints. Thus, the point-to-point network is most accurately described in this scenario.
