Common Bus Protocols:
Industrial Ethernet: Profinet, EtherNet/IP, EtherCAT, Modbus TCP. This is the current mainstream and trend, providing high-speed, high-bandwidth communication.
Traditional Fieldbus: PROFIBUS DP, DeviceNet, CANopen, CC-Link. Commonly used for retrofitting legacy systems or in specific industries.
Advantages: Enables true distributed I/O. Modules can be installed near devices far from the PLC control cabinet, connected by only a single communication cable (network cable or bus cable), greatly simplifying wiring.
Unparalleled Point Density and Space Saving: Integrating 32 points on a single module maximizes the use of DIN rail space and network node addresses, reducing per-point costs.
Distributed Architecture, Cabling Revolution: Pushing the I/O layer closer to the device, replacing dozens or even hundreds of control cables with a single network cable, saving significant amounts of cabling, cable trays, installation, and maintenance costs.
Flexible Configuration and Scalability: Most models support software configuration of channel input/output modes (if hardware supports it), adapting to future process changes. Easy to expand by adding modules.
High-Performance Integration: Thanks to modern industrial Ethernet, it enables microsecond-level synchronous data exchange, meeting the demands of high-speed applications.
