Status LEDs for ASM 456
LEDs
ON Lights up when there is logic voltage applied to the CM (is generated from the 24
V supply voltage.)
24 V DC Lights up when the 24 V supply voltage is connected to the CM.
The corresponding reader is active in processing a user command.
A flashing pattern indicates the last error to occur (see section "Error messages
(Page 47)").
Indicates the presence of a tag.
Indicates live communication with the reader. May also indicate malfunctions on
the reader.

Error correction
–
Check the PROFIBUS DP
•
connection.
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
software.
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 start-up.
