"Controller general":
The general controller status collects essential status information of the controller in two
1-byte communication objects. The "Controller status" object contains fundamental status
information (see Table 8). The "Status signal addition" object collects in a bit-orientated
manner further information that is not available via the "Controller status" object
(see Table 9). For example, controller extensions can evaluate the additional status
information, in order to be able to display all the necessary controller status information on
the extension display.
