Group-specific modal M auxiliary function display

Function
The output status and acknowledgement status of M auxiliary functions can be displayed on
the user interface on a group-specific basis.
Requirements
To implement function-oriented acknowledgement and display of M auxiliary functions, the
auxiliary functions must be managed in the PLC and, thus, in the user program itself. Therefore,
it is up to the PLC programmer to program the acknowledgement of these auxiliary functions.
He has to know which auxiliary functions in which group have to be acknowledged.
Standard
M auxiliary functions that are not managed by means of the PLC are identified by the NC as
"transferred" and output to the PLC. There is no functional acknowledgement for these auxiliary
functions. All M-auxiliary functions collected after a block search are also displayed so that the
operator knows which auxiliary functions will be output after a start following a block search.
PLC activities
In the case of auxiliary function groups that are managed by the PLC itself, the PLC user
program must acknowledge all auxiliary functions of this groups when Apply and Function
End are activated. The PLC programmer must know all the auxiliary functions of these groups.
Miscellaneous
Only the group-specific M auxiliary functions are displayed. The block-by-block display is also
retained. Up to 15 groups can be displayed, whereby only the last M function of a group that
was either collected or output to the PLC is displayed for each group. The M functions are
presented in various display modes depending on their status:
Status
Auxiliary function is collected
Auxiliary function is output from NCK to PLC
Auxiliary function has been transferred from NCK to PLC
and transport acknowledgement has taken place
Auxiliary function is managed by the PLC and has been
directly applied by the PLC.
Auxiliary function is managed by the PLC, and the function
acknowledgement has taken place.
