IO-Link Master
Function: It is the core controller of the IO-Link network. It is responsible for high-speed communication with upper-level control systems (such as PLCs) (via Profinet, EtherNet/IP, etc.), and manages bidirectional point-to-point communication with multiple lower-level IO-Link devices.
Functions: Powers IO-Link devices, configures parameters, collects process data (such as sensor values), and receives device status and diagnostic information.
Number of Ports: 4 ports
This means that one master module can connect to up to 4 IO-Link devices simultaneously.
This multi-port design is ideal for centrally connecting multiple sensors and actuators in densely populated workstations (such as assembly stations and testing stations).
Class A: Only supports three communication rates: COM1 (4.8 kbps), COM2 (38.4 kbps), and COM3 (230.4 kbps). It does not support the fastest COM3 (230.4 kbps) rate.
Simplified Wiring: Transforms traditional point-to-point hard wiring (each sensor requiring a multi-core cable back to the PLC) into a star connection using a single standard 3- or 4-wire M12 cable, saving up to 90% of cabling and wiring work.
Digitalization and Intelligence: Not only can it transmit switch signals (0/1), but it can also transmit rich process data (such as analog values, text information) and parameter data.
Powerful Diagnostic Functions: Real-time monitoring of equipment status (short circuit, open circuit, overload, contamination, overheating, etc.) enables predictive maintenance.
Seamless Replacement and Parameterization: When replacing equipment, the master station can automatically download stored parameters to the new equipment, achieving "plug and play" and greatly reducing downtime.
