7.3.3 Software-side setting (SIMATIC IPC)
In contrast to SINUMERIK PCUs, SIMATIC IPCs have no service switch on the hardware side
for selecting the mode. Therefore, on the SIMATIC devices, you can define the mode on the
software side in the configuration filepcuhwsvc.ini.
Archiving of the configuration file pcuhwsvc.ini
The template is located in directory C:\ProgramData\Siemens\MotionControl
\siemens\System\etc\
Do not overwrite this template, but save a copy of the template pcuhwsvc.ini in one of the
user directories:
● C:\ProgramData\Siemens\MotionControl\user\System\etc\
● C:\ProgramData\Siemens\MotionControl\oem\System\etc\
● C:\ProgramData\Siemens\MotionControl\addon\System\etc\
You can find detailed information on the configuration files in Chapter: Directory structure and
