4.2.6 Replacing the Slide-in Strips
General Information
The 14 PLC function keys on the front of the BTV 20 can be labeled by using
a slide-in strip . The key row above the PLC function keys (OP2...OP9) is also
freely configurable using slide-in strips.
These strips, which are already inserted when the device is delivered, can be
freely replaced. Preprinted strips as well as a floppy-disk with templates are
also included in the scope of delivery so that you can create your own key
labels. How to replace the slide-in strips is decribed below.
