Some key features of the 2080-LC20-20QWB module include:

Communication Ports: It has two built-in Ethernet ports (10/100 Mbps) for network communication. These ports can be used for connecting the module to other devices, such as HMI (Human Machine Interface) panels, for programming and data exchange.

Digital I/O: The module provides 20 digital I/O points, which can be configured as either inputs or outputs. These I/O points can be used to interface with various sensors, actuators, and other devices in your automation system.

Power Supply: The module requires a separate 24V DC power supply for its operation. It does not provide its own power, so you need to ensure that the power supply is properly connected and capable of meeting the module's power requirements.

Programming Software: The 2080-LC20-20QWB module can be programmed using the Connected Components Workbench (CCW) software, which is a development environment specifically designed for the Micro800 series PLCs. CCW allows you to create and edit ladder logic programs, configure network settings, and monitor the status of the module.
