Initialize data
Next to the list of tag fields, the data of the selected memory area is displayed in HEX view.
With the "Read" button, the data is read from the transponder. The data read from the
transponder is highlighted in red to distinguish it from the data entered manually. If no values
are displayed, this means that no values have yet been read from the transponder.
Click the "Write" button to transfer the changed data to the transponder.
NOTICE
Reading/writing transponder data with an established connection to the controller
Note that, if a connection to the controller is established, the configuration of the readers is
performed via the controller. To enable transponder data to be read/written via the WBM,
the connected readers must have been initialized via the S7 controller beforehand.
