Reading from stick: Starts reading the data from the stick. This operation
is only possible with READ sticks. The data of the set data set is copied
to the LMS control. First a check is carried out as to whether the data
set may be imported. If the data set is incompatible, it must not be im­
ported. The display resets toNo operation and displays an error mes­
sage. The textReading from stick remains until the operation is comple­
ted or an error occurs. As soon as data transmission begins, the LMS
control goes in a parameterization position. As soon as parameters are
transferred, the LMS control must be unlocked transmission has ended.
Fault 183 parameterization is displayed.
Writing on stick: Starts writing the data from the LMS control to the stick.
This operation is only possible with WRITE sticks. The data is written in­
to the previously set data set. Before writing of the data begins, it is
checked whether the stick has sufficient capacity for the data and that
the respective customer number is correct. The textWriting on stick re­
mains until the operation is completed or a fault occurs.
PStick progress (7253)
The read or write progress is displayed as a percentage. If no operation is
active or a fault occurs, 0% is displayed.
