4 Functions and features
The fail-safe SmartPLC SafeLine AC422S integrates two AS-i masters, a safe
PLC, a non-safe PLC, a WEB server and an Ethernet/IP slave interface with 2-port
switch.
The fail-safe SmartPLC SafeLine
• controls the exchange of data to the sensor / actuator level.
• can be used as a safe and a non-safe controller (PLC).
• communicates with the higher-level control level via Ethernet/IP.
• visualises sensor/actuator data on the integrated WEB server.
• allows device configuration via the WEB server.
