Function selection (via operator panel front or PLC)

User interface or PLC
The user can control part program execution via the operator panel front or PLC.
Selection, activation, feedback
Selection
Different functions are available under the Program control soft key. Selection affects an
interface signal in the PLC. These signals are to be understood as selection signals from the
user interface, and do not activate the selected function.
Activation
These signal states must be transferred to another area of the data block to activate the
selected function. With program control by the PLC the signals are to be set directly.
Feedback
The activated functions are partly signaled back to the PLC from the NCK (see also Section
"Z1: NC/PLC interface signals (Page 1551)").
