SIMATIC NET CP 243-2 AS-i Master

C79000-G8976-C142/02

You can switch over to the slave display mode used by pressing the DISPLAY
button. You switch from group to group by pressing the DISPLAY button again: The
slave display is active when at least one group LED is lit.

If the CP 243-2 is in the configuration mode, all detected AS-i slaves are
displayed.

If the CP 243-2 is in the protected mode, all active AS-i slaves are displayed.
In the protected mode, failed or existing but unconfigured AS-i slaves are
indicated by the corresponding LED flashing.

The AS-i slaves are displayed in groups of five. The three group LEDs indicate
which group of 5 is being displayed in binary code. The 5 LEDs of the slave display
then indicate the detected or active AS-i slaves within the group.

To find out which slaves are active, select the group of 5 (line) corresponding to the
lit group LEDs. The currently lit LEDs of the slave display then indicate which
slaves within this group are currently active.

If a group of B slaves is displayed, the “B” LED is also lit.
