When a program is created as in (3) above, the screen can also be switched from
the PT using the Stand-alone functions (screen switch function) and it is not nec-
essary to input the same screen number twice. The step in (3) is not necessary if
the Stand-alone functions are not used.
Refer to 4-8 Determining the Screen Displayed on the PT for more information
on the Screen Switch Strobe Flag and notification of the currently displayed
screen.
The PT display can be changed by editing the contents of the numeral or charac-
ter-string memory table used for the display.
The method described below for changing the display involves copying the con-
tents of one memory table to another. Writing the source and destination
memory table numbers to the Copy Memory Table Setting words of the PT Sta-
tus Control Area allocated to the PC copies the contents of one memory table to
another in the PT, which changes the display.
This is a convenient method to display predetermined numbers of character
strings to suit the operating status. The changes are processed extremely rapid-
ly as the PT Status Control Area is used.
