14. SCREEN HARDCOPY
The screen hardcopy function outputs the information displayed on the
CNC screen as 640*480–dot bitmap data. This function makes it possible
to produce a hard copy of a still image displayed on the CNC.
The created bitmap data can be displayed on a PC.
Screen Hardcopy Procedure
1 Check the parameter settings. To use the screen hardcopy function,
set bit 7 of parameter 3301 to 1 and parameter 20 (I/O channel
selection) to 4 (memory card I/F). Set other relative parameters (bits
0, 2, and 3 of parameter 3301) as needed. In a multipath system, set
the parameters for each path.
2 Insert a memory card.
3 To start the function, set hardcopy start signal HDREQ (G67#7) to 1.
Alternatively, hold down the [SHIFT] key for five seconds.
4 To end the function, press the [CAN] key. Alternatively, set hard
copy stop signal HDABT (G67#6) to 1.
5 While the screen hardcopy operation is in progress, the hardcopy in
progress signal (F061#3) is tied to 1. For several tens of seconds (or
several seconds, for a monochrome LCD) before the hardcopy
operation ends, the screen image stands still.
6 When the screen hardcopy operation is completed, the hardcopy in
progress signal (F061#3) goes 0.
While the screen hardcopy operation is in progress, the screen image
keeps still. This means that the clock displayed on the screen indicates
the beginning and end of the operation. When the clock stops counting
seconds, the hard copy operation starts. The clock resumes counting
seconds when the screen hard copy operation ends.
