0~15 (yellow) : Slave status indicators.
ON : A slave is active, i.e. exchanging I/O data with the
master.
Flash : A slave is in the list of projected slaves, but not ac-
tive.
Slave 0 cannot be an active slave; if LED 0 flashes, a slave
with address 0 has been detected on the network.
+16 (yellow) : OFF : the status of slaves 0-15 is shown;
ON : the status of slaves 16-31 is shown.
If the setting of the CH switches 1-3 allows communication
with more than 15 slaves, this indicator will periodically turn
OFF and ON, to show the status of all slaves. If set to 15 or
fewer slaves, this LED will remain OFF.
2-1-3 Switches
CH The switches 1-3 select the number of IR words that the CQM1-
ARM21 will occupy in the CPU. This setting will influence the maxi-
mum number of AS-Interface slaves that can be addressed by the
PLC, and therefore the maximum number of I/O points that can be
connected.
