2.7 Activating Dialog Screen from NC Program
Introduction
The "Activate dialog screen from NC Program" function is also referred to as
"Command channel."
User-defined dialog screens can be displayed with HMI Advanced and HMI
Embedded.
• The appearance of the dialog screens is defined using configuration
(modification of COM file in the cycle directory). The dialog screen is called up
and closed again via function calls from the part program.
• User-configured dialog screens do not modify the HMI system software
(operator interface).
• User-defined dialog screens cannot be called up simultaneously in different
channels.
Application
The user-defined dialog screens can, for example, be used to assign defined
values to user variables (GUD) prior to running a part program.
• Up to 2 channels:
The "command channel" is activated by default for channels 1 and 2.
• More than 2 channels:
For HMI Advanced/PCU 50, the "command channel" must be activated (if the
SIEMENS measuring cycles have not yet been installed).
This requires a modification to be made to the file C:\MMC2\ COMIC.NSK in the
Setup operating area:
− Select file C:\MMC2\COMIC.NSK in the “Startup” operating area with
softkeys "HMI" → "Editor" → "Load".
− Insert the following text (after channel 1 and 2):
REM CHANNEL
TOPIC(machineswitch)
COMIC_START(COMIC001MachineSwitch"...)
[see text for first and second channel]
When the control is restarted (Off/On), the command channel is activated for
the corresponding channel.
