Acknowledging the current group error
1. Once you have identified the group error, acknowledge this error by setting the "init_run"
("MOBY Param") or "INIT" ("instance DB RFID standard profile") bit again.
After the group error has been acknowledged, the reader returns to processing mode. To
change to processing mode, the DISA bit is set automatically and reset again after the
status change. If the DISA bit was set manually previously, it remains set after the status
change.
2. Now set the corresponding status bits "IN_OP" and "RDY".
The description given in the chapter Result evaluation of a command (Page 264) applies
to the value of the output byte "error_MOBY" ("MOBY Param") or the output double word
"STATUS" ("instance DB RFID standard profile").
To acknowledge a group error via ASM or PROFINET IO:
● "ASM" or "PROFINET IO" must be configured as the controller in the adjustment support
(Connections➜ Integration ➜ Connection).
Note
Errors can be acknowledged via initialization with program selection
If the cause of error does not need to be identified: Acknowledge the error with program
selection via the initialization (Initialization (Page 247)).
