Function
The Quantum AS-i Master Module provides AS-i communications between the bus master module and the sensor/actuator slaves. One master module can control 31 slaves. Multiple master modules can be used in a single control system.
These sensor/actuators can be in the local CPU, an RIO, or a DIO drop adapter.
NOTE: This module is not available to directly exploit analog slaves (profile 7.1, 7.2, 7.3, 7.4) on an AS-i bus.
For detailed information see Modicon Quantum AS-i Master Module EIA 921 00 book ì

Description
1
Display block comprising 4 status indicator lamps (LEDs) for displaying the module operating modes:
  • B (green, 1 LED): Indicates, when on, data exchange between module and slave.
  • Active (green, 2 LEDs): when on, indicates AS-i module being services by the local CPU, RIO, or DIO drop adapter.
  • F (red, 1 LED): indicates, when on steady, module fault. Flashing shows external I/O fault (could indicate slave with address 0 or an AS-i bus configuration fault.
2
Display block of 32 indicator lamps (0 - 31, green) for diagnostics of the AS-i bus and display of the state of each slave connected to the bus.
3
AS-i (red): ON shows AS-i line not properly powered. Flashing shows automatic addressing enabled and a slave is "prévu" but not connected. OFF shows normal module function.
4
SLV/BUS (green): ON shows the LEDs 0-31 are in BUS display mode. Displays the slaves on the bus.
5
I/O Status (green): On shows the LEDs 0-31 are in SLV display mode. Displays the state of a selected slave.
6
Mode (Push Button): provides local diagnostics of the AS-i bus. Press this button longer than 1 sec. to change the mode. In slave mode use the Address Push Button to scroll among the 32 addresses.
7
Address (Push Button): Pressing this button (in slave mode) scrolls through the slaves. Press longer than 1 sec. to reverse direction of the scroll.
8
AS-i Channel cable connector - connects module to AS-i cable and AS-i power supply.
