Here are some key features of the 1784-PCD1 module:

ControlNet Network Interface: It supports the ControlNet communication protocol, allowing the module to communicate with other devices on a ControlNet network.

Digital and Analog I/O: The module offers digital input and output points as well as analog input and output channels. These I/O points can be used to interface with various field devices such as sensors, actuators, switches, and transducers.

Embedded Processor: The module contains an embedded processor that handles the communication tasks and executes user-defined logic and programs.

Configuration and Programming: The 1784-PCD1 module can be configured and programmed using Rockwell Automation's programming software, such as RSLogix 5000 or Studio 5000. These software tools provide a user-friendly environment for configuring network settings, defining I/O tags, and developing ladder logic or other programming languages supported by Rockwell Automation.
