Introduction to Freeport Communication
This document details the application of Siemens' S7-200 SMART CPU for serial communication using the Transmit (XMT) and Receive (RCV) instructions in Freeport mode. This mode allows direct control over the CPU's serial communication ports (RS485 and RS232) for custom data transmission and reception protocols.
Explore how to configure hardware, integrate projects, and implement operational logic for seamless data exchange between S7-200 SMART PLCs and other devices. This guide is essential for engineers and technicians working with industrial automation systems requiring flexible serial communication capabilities.
