How Do Ethernet I/O Modules Support Large Networks?
They can handle high channel counts with multiple simultaneous connections, allowing many PLCs or SCADA systems to read and write data without bottlenecks.

What About Protocol Compatibility?
Many units support Modbus TCP, EtherNet/IP and Profinet in one device. This multi-protocol capability avoids lock-in and makes it easier to integrate mixed-vendor systems.

Which Features Help in Industrial Sites?
DIN-rail mounting, dual Ethernet ports with daisy-chain capability and watchdog timers keep systems stable, even in the event of partial network failure.
