CANopen is a communication protocol based on CANbus that facilitates real-time communication between different devices and components. This system is also used to exchange data and integrate industrial automation networks.

DeviceNet is an application-level protocol based on the Controller Area Network (CAN) protocol. It's used for communication between programmable logic controllers (PLC) and control devices in automation environments through a DeviceNet scanner.

Ethernet/IP is an industrial network protocol that allows communication between devices over an Ethernet network using Common Industrial Protocol (CIP). Ethernet/IP is known for fast data transfer rates and its ability to support large networks.

Modbus is a serial-based protocol that allows devices to communicate with each other over a network. Modbus is known for its simplicity and compatibility with a wide range of devices and systems. Often used for monitoring and controlling devices such as sensors, actuators, and programmable logic controllers (PLC).

Modbus/TCP is an extension of Modbus protocol that allows Modbus to be used over TCP/IP Ethernet networks. It enables devices to communicate over Ethernet networks and is suitable for applications that require fast data exchanges.

Profibus DP is a Fieldbus protocol that offers fast data transfer rates and supports large networks. It allows devices to communicate in real time and is commonly used in robotics and process automation applications.

Optional Identifies that the device does not have a factory-installed communication module. They can be purchased separately based on the protocol application needed.
