Hard keys 1 - 9 are preassigned as follows:
Key designation
HK1
HK2
HK3
HK4
HK5
Configuration
The configuring is realized in the systemconfiguration.ini configuration file in the section
[keyconfiguration]. Each line defines what is known as a hard key event. A hard key event is
the n-th actuation of a specific hard key. For example, the second and third actuation of a
specific hard key can result in different responses.
The entries in the systemconfiguration.ini configuration file can be overwritten with user-
specific settings. The \user\sinumerik\hmi\cfg and \oem\sinumerik\hmi\cfg directories are
available for this purpose.
The lines for configuring the hard key events have the following structure:
KEYx.n = Area:=area, Dialog:=dialog, Screen:=screen, Forms:=form, Menus:=menu,
Action:=menu.action, Cmdline:=cmdline
KEYx.n = Area:=area, Dialog:=dialog, Cmdline:=cmdline, Action:= action
x: Number of the hard key, range of values: 1 – 254
n: Event number – corresponds to the nth actuation of the hard key, value range: 0 – 9
Precondition
The PLC user program must fulfill the following requirement:
Only one hard key is processed. As a consequence, a new request can only be set if the
operating software has acknowledged the previous request. If the PLC user program derives
the hard key from an MCP key, it must provide sufficient buffer storage of the key(s) to
ensure that no fast keystrokes are lost.
