To activate a part program, it must be selected as discussed in section 7.3.
To select a program for automatic execution, follow the steps below.
Important: Consider the following when selecting a program:
The control will not allow the selection of a program for execution if
that program file is still open for editing. See chapter 5 on how to exit
the edit mode.
Note that the system installer may have written PAL to allow some other
method of part program selection. Refer to the documentation prepared
by the system installer for additional information.
Before selecting a part program to activate the input device must have
been previously selected as discussed in section 7.2. Note that the
default condition is to select the part program out of control memory.
If a program was previously activated and not deactivated, the control
will not allow a different part program to be selected. If a different part
program is desired, you must first deactivate the active program as
discussed in section 7.4.
