7: Update control signals to axes:
The purpose of function 7 is to transmit important control signals at high speed in between
cyclic data transfers. The data byte 4 of application interface DB31 to DB61 is transferred to
the NC. The transfer is performed for all activated axes. This function can be used, for
example, to transfer a feed stop outside the PLC cycle.
The following signals are relevant:
