Hardkeys
All keys - also the PLC keys - are subsequently referred to as hardkeys. A maximum of 254
hardkeys can be defined. The following allocation applies:
Key number
Key 1 – key 9
Key 10 – key 49
Key 50 – key 254
Key 50 – key 81
Key 255
Hardkeys 1 - 9 are pre-assigned as follows:
Key designation
HK1
HK2
HK3
HK4
HK5
HK6
Configuration
The configuring is realized in the systemconfiguration.ini configuration file in the section
[keyconfiguration]. Each line defines what is known as a hardkey event. A hardkey event is
the n-th actuation of a specific hardkey. For example, the second and third actuation of a
specific hardkey can result in different responses.
The entries in the systemconfiguration.ini configuration file can be overwritten with user-
specific settings. The directories [System user directory]/cfg and [System oem directory]/cfg
are available for this purpose.
