FUJI AS-Interface_AS-i Masters Masters
FLEX-PC
Description

The NJ-ASL AS-i master, mounted on the CPU base unit of the FLEX-PC NJ series PLC, communicates with devices on the AS-i bus.

. The slaves’ configuration can be registered by a toggle switch on the front of the AS-i master.
. The status of the AS-i bus is indicated by the LEDs on the AS-i master, e.g., showing disconnection of slaves, AS-i power supply failure, and automatic addressing availability.
. The 7-segment LED indicates the addresses of disconnected slaves (in protect mode) and configured slaves (in configuration mode).
. AS-i specification: V2.0
