The "SET" button is required for configuring the CP in standard operation.
The button is only activated when the CPU is in the STOP mode.
If the CP is in the
configuration mode
, the CP is configured automatically
when the button is pressed. Configuration involves the following steps:
•
The CP stores the existing slave configuration, which is indicated by the
slave display, as desired configuration in the Flash-ROM.
•
The CP then changes to the
protected mode
.
If the CP is in the
protected mode
, pressing the button "SET" the CP
switches to the
configuration mode
.

fault
The LED is lit, when:
•
the CP is in the
protected mode
and an AS-i configuration error has
occurred (for example slave failed)
•
the CP detects an internal fault (e.g. Flash-ROM defective)
•
the CP cannot change to the mode requested with the "SET" button
(for example a slave exists with address 0).
RUN
green Indicates that the CP has started up correctly.

AS-i Power Fail
This indicates that the voltage supplied to the AS-i cable by the AS-i power
supply unit is too low or there is a complete power fail.
CER
yellow Configuration error
This LED indicates whether the slave configuration detected on the AS-i
cable matches the configuration configured on the CP (LPS). If they do not
match, the CER LED is lit.
AUP green
Autoprog
