LED off - no connection to camera or error status on camera
LED flashes - a flashing pattern shows the value of "number_MDS".
Indicates live communication with the reader. May also indicate malfunctions on
the reader.
In multitag mode, this LED uses a flash interval to indicate the number of data carriers currently

Error handling
–
Check the PROFIBUS DP connec-
•
tion.
Check the DP Master
•
Check all cables on your
•
PROFIBUS DP network.
Check whether the connector plugs
•
for the PROFIBUS DP are securely
plugged into the ASM.
Check the project for the ASM
•
(input/output, PROFIBUS address).
Correct GSD file being used?
•
Check the PROFIBUS address set
•
in ASM and/or in the project soft-
ware.
Check the project for the ASM
•
(station type).
Replace the ASM.
•
Evaluate the diagnostic information.
•
Set the address in the range 1 to 99
•
and carry out new run-up.
