When you click on this button, you delete all diag-
nostics entries stored in the EPROM.
Note
This button is enabled only when there are diagnos-

Persistent storage of a bad image
While a bad image is being stored in the EPROM, it remains possible to operate the reader
and to control it from an automation system. This is, however, delayed since the storage of
image data in read-only memory can take a relatively long time.
Persistent storage of diagnostics entries
The following restrictions apply to storing diagnostics entries in the EPROM:
●
The processing time of the currently acquired code increases by the time required to
store the diagnostics entries. The time required to store a diagnostics entry in the
EPROM is as follows:
–
At an ambient temperature of 25 ºC approximately 1 ms.
–
At an ambient temperature of 50 ºC approximately 32 ms.
●
Operating the reader and controlling it from an automation system are possible, however
input is delayed.
Note
Ethernet or PROFINET connection: longer history,
The storage times shown above apply only when there is no connection over Ethernet or
PROFINET. If there is such a connection, the specified time increases and increases
more the higher the network load.
