Reading out the diagnostics address for S7 functions
For certain functions (e.g. reading out diagnostics), the diagnostics address is subsequently
necessary. You obtain this using the context menu (right-click on the slave) and the function
"Object properties". You can then close the window again by clicking the "OK" button.
