6.13.10 PLC Soft Keys
In the following operating modes you can display your own soft keys through
the PLC:
n MANUAL
n ELECTRONIC HANDWHEEL
n POSITIONING WITH MANUAL DATA INPUT
n PROGRAM RUN, FULL SEQUENCE
n PROGRAM RUN, SINGLE BLOCK
You can create the soft keys with PLCdesign.
When a PLC soft key is pressed the NC enters the soft-key number in W302.
On the rising edge of the keystroke it enters the soft-key number; on the
falling edge it enters –1. The PLC can enter –1 itself after recognizing the soft-
key number.
With Module 9200 you can display entire soft-key rows. With Module 9201
you can show individual soft keys. With Module 9202 you can switch to the
display with PLC soft keys and PLC windows. This module works like the
screen management key.
