Group errors
Identifying and acknowledging group errors
If the "IN_OP" status bit is not set and the status display is valid, there is a group error.
Identifying and acknowledging this group error involves two stages. The procedure is as
described below.
Identifying the current group error
Note
Using initialization without program selection
Only possible when using program selection without initialization: see Initialization
(Page 247).
●
Set the "MOBY Param".init_run (FB45) or "instance DB RFID standard profile.INIT" (RFID
standard profile) bit.
A value identifying the group error is now present in the output byte "error_MOBY" ("MOBY
Param") or output double word "STATUS" ("instance DB RFID standard profile"). You can
find a list of possible group errors and the corresponding error codes in chapter Alarm, fault
and system messages (Page 333).
As a general rule: If an "init_run" or "INIT" is executed and the "IN_OP" status bit is not set
afterwards, the reader is in the group error status.
●
To identify the error, use the list provided in chapter Alarm, fault and system messages
●
Do not use the description in the function manual of FB45 or RFID standard profile.
