Displacement Mechanism For Tcus - Siemens SINUMERIK 840D sl Equipment Manual

General information and networking
4.3 Networking
Prerequisite
Note
The "Operation without SINUMERIK OP" option is required when using more than 1 external VNC
Viewer.
Operator control without SINUMERIK OP
If the "Operation without SINUMERIK OP" option is set, then a list of viewers that can be assigned
in tcu.ini is handled by the system just like internal viewers (=TCU); this means that these viewers
have full user authorization and participate in the user rights management. Towards the outside,
they behave just the same as the viewer on the SINUMERIK operator panels.
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 control 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 configuration file config.ini, as for a TCU, i.e. the settings to be made to a TCU are
not possible for such an operator control unit (power-up behavior, displacement, t:m:n);
however, the displacement mechanism to 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=
The desired screen resolution can also be set in the file tcu.ini:
[VNCServer]
Resolution = ...
