Loading of the CPU with the UWF write filter
To load a project on the CPU, also disable the UWF write filter on the partition "C:". To do so, enter the following commands
in the Windows Command Prompt:
uwfmgr filter disable
uwfmgr volume unprotect c:
After loading, activate the protection again with the following commands:
uwfmgr filter enable
uwfmgr volume protect c:
"Limit and enable password legitimation" instruction (ENDIS_PW)
To disable the protection with an F-CPU, you must uninstall the CPU and reinstall it. A repair installation is not sufficient to
reset the configured access protection via the ENDIS block.
Monitor cable on DisplayPort X70/X71
If the monitor cable is connected to the DisplayPort X70/X71 while the SIMATIC IPC is switched on, it can happen that a
newly inserted display is not correctly detected and that the display contents are not shown correctly. In rare cases this can
lead to the "Defect" of the SIMATIC CPU1507S (F) Software Controller.
Do not plug or unplug the display cable of the SIMATIC IPC while the CPU1507S Software Controller is in operation. If the
behavior occurs, you need to restart the SIMATIC IPC with connected display.
We recommend leaving the display connected to the IPC or operating the IPC without connected display at all times.
