Online parameterisation of the device
Devices can also be parameterised online. In doing so, you can also select whether only individual param-
eters(single)orallparameters(all)ofagrouparereadfromthedevice(upload)orareloadedintothedevice
(download).
It is also possible to transfer individual parameters or all parameters of a group cyclically in monitor mode.
This may be helpful particularly for start-up purposes.
