Upon the recognition that the new M-function is M14 or M15, the follow-up program part
is jumped to
M14: The output O_ToolDown is set and a timer of 5s is started. If input I_ToolDown is set
after max. 5s, the function is switched, otherwise an error message occurs. The error mes-
sage is made via the function SPSERROR that opens
an error screen in the StdHMI via the
error number (F_TOOL_UP_KI).
