Siemens SINUMERIK ONE MCP 2400.4c Equipment Manual

Obtaining user authorization
On a TCU that has no user authorization, the 󹪝rst key that is pressed serves exclusively to request
the user authorization, i.e. this key is not evaluated by the operating software.
The settings for the right to veto are stored in 󹪝le tcu.ini and are only e󹪜ective if the
operating software is installed on the PCU. At the OP of the TCU, the operating software can
be operated in exactly the same way as an OP directly connected to the PCU.
Note
These operator input sequence steps must only be carried out by quali󹪝ed personnel!
4.3.2.11 Example: How to select the behavior of the TCUs during boot up
Example: Distributing boot support across two PCUs
To distribute boot support over two PCUs, "Boot support runtime and con󹪝guration only (TFTP/
FTP)" must be selected on PCU_1 and "Boot support IP address only (DHCP)" must be selected on
PCU_2.
The "No boot support" con󹪝guration must be selected on PCU_3:

connected TCUs. PCU_3 is not involved in booting the TCUs, it is however displayed by the
TCUs using VNC.
