Displacement Mechanism For Tcus - Siemens SINUMERIK 840DE sl Manual

Note
The following entries are evaluated by SINUMERIK Operate:
● VNCServer/VetoMode
● VNCServer/AlarmBoxTimeOut
● VNCServer/FocusTimeout
● VNCServer/AdaptResolution
● VNCServer/MaxActiveTCUs
● VNCViewer/ExternalViewerSecurityPolicy
Restrictions
Restrictions for such external operator control units are:
● Neither MCP and direct keys nor an EKS system can be assigned. This also means that
these devices cannot be activated to be an operator control unit in the system.
● Direct keys cannot be triggered, i.e. the softkeys to the direct keys can be triggered in the
operating software. However, the keys do not appear in the direct key image to the PLC.
● There is no config.ini configuration file, as for a TCU, i.e. a configuration for a TCU is not
possible for such an operator control unit (power-up behavior, displacement, t:m:n);
however, the displacement mechanism on the external operator control units is effective.
● An external operator control unit is never signaled as active operator station in the PLC.
Configuring the external operator control units in the tcu.ini file in section:
[externalTcu]
# EXTERNAL TCU IP-ADDRESSES
# List of accepted TCUs in IP-V4-format (index 1 to maximal 16)
ExternalTcuIP_1=
You can also set the desired screen resolution in the tcu.ini file:
[VNCServer]
Resolution = ...

Displacement mechanism for TCUs

To operate a machine with more operating stations then the maximum number, the
displacement mechanism ensures that only the permitted number of TCUs are active in a
shadowing group. The remaining TCUs are switched to passive mode, which means they no
longer represent a load with regard to the resources. Thus the number of TCUs that can be
connected to one HMI application is practically no longer limited. The limitation is the number
of concurrently active TCUs.
