● "Electronic key system index - EKS" (0-255)
Specifies the index of the associated EKS; see column "EKS" on the user interface.
● "Enable direct keys" (yes/no)
Specifies whether direct keys are registered with the PLC (yes) or are treated as ordinary
keys (no); see column "DCK" on the user interface.
● "Virtual Keyboard" (Auto/On/Off)
Specifies whether a virtual keyboard is shown on the screen for touch screens.
Depending on the panel features (Auto), the HMI decides whether a touch screen or
keyboard is available.
This parameter can also be set manually (On/Off).
● "Software Caps-Lock" (Auto/On/Off)
The HMI can manage the Caps-Lock status of a keyboard in the software itself, when, for
example, the key is not available. This is normally (Auto) switched on via a display machine
data item. This machine data item can be overwritten individually for the TCU with the
setting (On/Off).
● "Emulation Type" (TCU/TCU20.2/TCU30.3, only for modular TCU30.3)
Specifies which TCU type is to be emulated when the TCU30.3 is operated as replacement
device for an older TCU or as new device on a software version older than 4.7 SP2.
● "Screen Rotation" (0°/90°/180°/-90°/Auto)
Specifies in which angle the screen is to be rotated in the software. This is useful when the
panel is to be rotated during installation.
For the "Auto" setting, the rotation of the display is taken from the panel.
● "Old VNC Password"
If a password has already been set, it must be entered here so that it can be changed. If
no password has been set, this field is grayed-out. The existing password can also be
deleted if, after entering the old password, no new password is to be entered at "Set VNC
Password" and "Repeat Password".
● "Set VNC Password"
Assign a password which is stored in the TCU and, if required, sent to the server when the
VNC connection is established.
● "Repeat Password"
Repeat the password entered at "Set VNC Password".
The values are applied and stored with "OK". You can also make any subsequent adaptations
or changes by calling up the "Commissioning" operating area → menu forward key → "OPs"
softkey on the user interface.
5.4.5 Operating the menu for a new TCU or spare part TCU
Registering a new TCU
When an unknown TCU (i.e. not yet registered with the boot server) is started, a selection
menu containing both the "New" and "Replacement for existing panel" items is displayed. The
accessibility of all the registered TCUs is tested in the background.
The status of this test is displayed in the message line: "(0/3 panels inactive)".
