From here you can switch module states, initialize the axes etc. etc. The panel also allows you to tell mode switching to ignore a module. All actions, such as presetting, will work but only on the axes selected. The hydraulics is usually in the ignore state. This is a safety precaution and does not reflect on any defect in the system.
Selected modules show that they are actually initialized.
Modules in blue are selected as necessary by mode switching. A so modules on side B are in black and not required. As mentioned earlier, this task is undertaken by the prsControl module. Presetting can be done in two ways. It is important to distinguish here between offsets applied at preset time and all subsequent offsets.
