The following two methods are available for printing out a hard copy of the cur-
rently displayed screen.
Using a Touch Switch with The Screen Print Function
When creating the screen to be printed out, register a touch switch with the
screen print touch switch for it.
When this screen is displayed during operation, pressing the touch switch will
cause a hard copy of the screen to be printed out.
For details, refer to 2-7 Touch Switches (page 110).
S The PT continues operation during printing.
S If a touch switch with the function for stopping printing has been registered for
the screen, printing can be stopped by pressing this touch switch.
S The Device Monitor screens have a screen print touch switch.
Method Using The PT Status Control Bits
When the status of the screen printing bit (bit 7) of the PT status control bits is set
to 1 (ON), a hard copy of the screen displayed at that time is printed out.
For details, refer to 2-2-1 PT Status Control Area (Host to PT) (page 46).
S The PT continues operation during printing.
S Before setting the status of the screen printing bit to 1 (ON), confirm that the
status of printer operating status bit (bit 7) of the PT status notify bits is 0 (OFF).
S When printing is executed using the PT status control bits, it is not possible to
stop printing part way through.
Printing Example
The display history and alarm history recorded in the PT can be printed out by
calling the display history and alarm history display screens from the System
Menu.
To print when the PT is running, display a display history dedicated screen, or a
screen for which an alarm history is registered, then print it using the screen print
function.
Switch between screens by pressing a touch switch allocated the screen switch-
ing function, or by writing the screen number to the screen switch setting word in
the PT status control area. To print a screen, either press a touch switch allo-
cated the screen print function or set the screen printing bit in the PT status con-
trol bits to ON. (Turning ON the screen print bit produces a hard copy of the
screen.)
The display history dedicated screens are:
Occurrence history screen:
Frequency history screen:
