Performance and system design freedom

The high-speed EtherCAT fieldbus on the iE 350 PLC is fast enough to handle distributed I/O with

one main controller and hundreds of distributed analogue and digital I/O and communication

channels in multiple locations. You get the same update speed for local and distributed I/O nodes in an

external network.

The system software launches very quickly and offers fail-safe start-up with two operating

system images separated from the application. If one image fails to start up the iE 350 PLC,

the controller falls back to the other image and completes start-up.

Each image can be updated remotely. After a successful start-up after an image update,

the new image can be set as active. The iE 350 PLC uses a special file system that tolerates

sudden loss of power and monitors itself for errors.

The high-performance features of the iE 350 PLC also include direct 690 VAC 3-phase grid measurement,

allowing you to measure voltage and frequency in a wide range from 2 to 897 VAC.
