The clock on the CNC screen freezes when the screen capture begins to indicate when to release the shift key. Pressing and holding down the shift key on the MDI panel for five seconds starts the screen hard copy function. The device can also be specified on the Settings page. Setting parameter 20 to 17 selects the USB memory port. Setting parameter 20 to 4 selects the PCMCIA memory card. The device to which the screen hard copy function saves the bitmap file is determined by CNC parameter 20. The Series 16i/18i/21i MODEL A and B and the Series 0i-MODEL C have an additional bit in parameter 3301 that controls whether monochrome bitmaps are inverted. If parameter (H16) 3301#0=1, a 16 color bitmap is created.
If parameter 3301#0=0 (H16), a 256 color bitmap is created. Parameter 3301 bit 0 controls the depth of the bitmap file created. If parameter (HDC) 3301#7=0, the hard copy function is disabled. If parameter (HDC) 3301#7=1, the hard copy function is enabled. The screen hard copy function can be enabled and disabled with parameter 3301 bit 7. Once saved, the bitmap file can be displayed, edited or e-mailed on a personal computer. Applications include creating set-up documentation, recording alarms and issues for maintenance and e-mailing condition information to remote resources such as a machine tool builder service department.įANUC America Corporation's screen hard copy function converts the information on a CNC screen to a bitmap (.BMP) format graphic file and saves it to either a memory card inserted into the PCMCIA port or to a USB memory stick inserted into the USB port.
There are times when it is useful to capture the information displayed on a CNC screen.
