DEIF iE 350 PLC Performance and system design freedom

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.

Built-in operational cyber security features

With connected and online controllers, operational security is critical.

The Linux system in the iE 350 PLC provides cutting-edge security features.

For example, boot and firmware updates can only be carried out with signed update packages.

By default, there is only one user (admin) account on the iE 350 PLC. Still, you can create and manage

multiple users and access rights to ensure that the necessary users can handle the unit

while protecting theiE 350 PLC from unauthorised access.

CODESYS web visualisation is managed through certificate handling via the system web page.

Authentication keys are added via system web configuration, and the iE 350 PLC builds

on standard secure file transfer and access protocols like SSH and SCP.

Finally, the Linux system is less vulnerable to ordinary computer virus attacks than Windows-based PLCs.
