Reset active status

Function:
Resetting the active status on worn tools.
This PI service is used to search for all tools with the tool status active and disabled. The
active status is then canceled for these tools. Potentially appropriate times for this PI service
are the negative edge of VDI signal "tool disable ineffective", an end of program, or a
channel reset. This PI service is intended mainly for the PLC, since it knows when the
disabled tool is finally no longer to be used.
