HEIDENHAIN iTNC 530 HSCI - Machine Operating Panel

1404 HEIDENHAIN Technical Manual iTNC 530 HSCI
8.4.2 Machine operating panel
The machine operating panel has its own PLC inputs and outputs. These are
transmitted via HSCI. You must configure the inputs and outputs using
IOconfig, and evaluate them in the PLC.
You can activate specific functions by linking the PLC inputs with the
corresponding markers and words.
You can store the pressing of an axis-direction button:
 With MP7680 bit 0, enable the memory function.
 Use M4562 to save a depressed axis direction key. This means that the axis
will move until there is an NC STOP.
If the LSV2 connection is active, the NC Start and NC Stop commands can be
transmitted. PLC Marker M4230 functions like NC Start, and M4231 like NC
Stop, unless the PLC markers are reset by the PLC program. The two markers
for NC Start (M4564, M4230) are OR-gated in the PLC run-time system. The
two markers for NC Stop (M4560, M4231) are AND-gated (if one marker = 0,
then an NC Stop is triggered). After evaluating the states, the two markers of
the LSV2 connection are set to their original state again (M4230=0,
M4231=1).
