Technical details and manufacturing context for Communication Module

Definition
The Communication Module serves as the interface for data transmission within the Industrial System, facilitating real-time monitoring, control commands, and information exchange with supervisory systems, other machines, or cloud platforms. It ensures reliable connectivity and protocol conversion for industrial automation.
Working Principle
The module physically operates by receiving electrical signals from the Industrial System's controller, converting them into standardized communication protocols (e.g., Ethernet, serial, wireless), and transmitting them via physical connectors or antennas. It also receives incoming data, converts it back to electrical signals, and relays it to the system's processing units.
