If the control is operational, 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, a "*" 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."
