10 Appendix
10.1 Codes indicated by the Display
In the basic state of the configuration mode, the display shows the addresses of
all detected slaves at a rate of two per second one after the other. A blank display
indicates that the LDS is empty, no slaves were detected.
In the basic state of the protected operating mode, the display is either blank or
displays the address of a faulty assignment (
see chapter ).
During manual address programming, the slave address display has a different
meaning (
see chapter 6.2.4).
All displayed numbers bigger than 31 which can not be interpreted as a slave
address are status or error messages of the master. They have the following me
-
anings:
39 Advanced AS-i diagnostics: After pressing the ’set’-button a short-time AS-i
power failure occured.
40 The AS-i master is in offline phase.
41 The AS-i master is in detection phase.
42 The AS-i master is in activation phase.
43 The AS-i master starts the normal operating mode.
70 Hardware error: The AS-i master’s EEPROM cannot be written.
71 Wrong PIC-type.
72 Hardware error: wrong PIC-processor.
73 Hardware error: wrong PIC-processor.
74 Checksum error in the EEPROM.
75 Error in the internal RAM.
76 Error in the external RAM.
77 AS-i control software error: Stack overflow (AS-i control II)
78 AS-i control software error: Checksum error in the control program.
80 Error while attempting to exit the configuration mode: A slave with address
zero exists.
81 General error while changing a slave address.
82 The front panel operation is blocked. Until repowering-up the device can
only be accessed from the host via the interface.
83 Program reset of the AS-i Control programm: The AS-i Control programm is
being read out of EEPROM and copied into the RAM.
88 Display test while starting up the AS-i master
90 Error while changing a slave address in protected operating mode: No
slave with address 0 existing.
91 Error while changing slave address: Target address is already used.
92 Error while changing slave address: New address could not be set.
93 Error while changing slave address: New address could only be stored vol-
atilely in the slave.
