Search strategy
If a program (with no path) is required by the simulation, the following directories
are searched:
1. File in current NCK workpiece directory
2. File in current workpiece directory of HMI Advanced
3. File in NCK subroutine/main program directory
4. File in HMI Advanced subroutine/main program directory
5. File in NCK user cycle directory
6. File in HMI user cycle directory
7. File in NCK manufacturer directory
8. File in HMI manufacturer directory
9. File in NCK standard cycle directory
10. File in HMI standard cycle directory
If a program is not present in the simulation, it is reloaded from the NC or the HMI.
All programs (apart from cycles) that are loaded into the simulation are deleted
from the simulation again in the event of a workpiece change. If one of these
programs is needed again by the simulation, it is reloaded.
Program selection
If a part program for a workpiece is selected for the simulation, the following
actions are executed:
1. All tools are cleared with the file TO_CLEAR.INI (in HMI_ADV\DP\SIM) (if
present).
2. If WPD_INI_MODE = 1 (see item 5) and if a TOA file with the selected program
name exists in the workpiece directory, this file is loaded into the active file
system for the simulation (otherwise file TO_INI.INI if it exists in the data
management system in \DP.DIR\SIM.DIR).
3. If tool management is active, the file TO_ADDON.INI (in HMI_ADV\DP\SIM) is
also loaded into the simulation and executed.
4. Workpieces: an initialization file with the workpiece name is loaded into the
simulation
5. Workpieces:
• MD 11280 WPD_INI_MODE = 1
All files (RPA, GUD, SEA, UFR, PRO, CEC, TMA) with the part program names
are loaded into the passive file system in the simulation. Program-specific TOA
files are loaded directly into the active file system for the simulation, all tools are
first cleared and then, if tool management is active, the file TO_ADDON.INI (in
HMI_ADV\DP\SIM) is loaded into the simulation and executed.
• MD 11280 WPD_INI_MODE = 0 (as before)
A TOA file with the workpiece name (search sequence NC, then HMI) is loaded
into the simulation, otherwise the first TOA file for the workpiece (search
sequence NC, then HMI) is loaded into the simulation.
The part program is then loaded into the simulation and selected.
