The stick status is shown below:
No stick: The LMS control has not detected a stick (the stick may not be
inserted).
Stick ready: Basic condition, stick is detected, no action active, no error
present.
Writing on stick: Data is copied (backup) from the LMS control to the
stick.
Reading from stick: Data is transferred from the stick to the LMS control.
Writing error: An error occurred when copying the data from the LMS
control to the stick. The operation was aborted.
Reading error: An error occurred when copying the data from the stick to
the LMS control.. The operation was aborted. The control LMS is locked.
Status change to read lock.
Incompatible data set: Data set does not match LMS control.
Compatibility conditions are not met. The data set can not be imported.
Wrong stick type: Stick type does not match selected action. E.g.
reading from write stick or writing to read stick is not possible.
Stick format error: Incorrect customer number on the stick or data format
on the stick is unknown and cannot be evaluated by the LMS control.
Check data set: During transmission of a data set from the stick to the
LMS control a problem occurred, but it did not lead to an abort.
Data set disabled: The data set may not be transferred into the LMS
control (read protected).
