6.4.5 Control is in operation
If the control is in operation, i.e. a positioning or M-function is performed, the status window
displays a large asterisk "*". If a current NC-program is interrupted with the external stop key, the "*"
will flash in the status-display. This information is transmitted to the PLC through the markers
M2183 and M2184. M2183 and M2184 are effective in the operating modes "Positioning with MDI",
"Program run/single block" and "Program run/full sequence".

6.4.6 Cancel status-display
A machine parameter can be used to decide whether with the M-functions M02 and M30, as well as
with NC-block "END PGM" the status-display should be reset and the contents of the Q-parameters
erased. All the programmed values in the status-display, e.g. tool number, tool length, tool radius,
scaling factor, datum-shift, feed-rate etc. will then be reset. The Q-parameters will all be set to 0.
