Application Functions
/SEL0 to /SEL7 (Program Step Selection Inputs) Signals
These signals specify the program step.
You can change the settings for the /SEL0 to /SEL7 signals with PnB06 to PnB0D. If you
change the settings for the /SEL0 to /SEL4 signals, set the /MODE 0/1 signal to ON (closed)
(Mode 0). If you change the settings for the /SEL5 to /SEL7 signals, the setting of the /MODE
0/1 signal is irrelevant.
