Function and Positioning

As a dedicated multi‑protocol expansion insert, the 3IF621.9 extends the 2005 system with two isolated communication channels: one for RS485/RS422 serial communication and one for CAN bus networking. It acts as a communication bridge between the main controller and serial devices, CANopen slaves, or network nodes, supporting master/slave modes and basic protocol conversion. By offloading communication tasks from the CPU, it improves overall system efficiency and reliability. It is widely used to connect drives, sensors, HMIs, and CAN‑based I/O modules, playing a key role in distributed control and multi‑protocol system integration.
