If another part program from the same workpiece is selected for the simulation, it is
loaded into the simulation together with the associated data (if MD 11280
WPD_INI_MODE = 1) and then selected.
If a part program from another workpiece is selected, the previous workpiece is
removed from the simulation.
If a workpiece is selected for the simulation, the part program with the workpiece
name is loaded into the simulation together with its data and the workpiece
selected. If the part program with the workpiece name does not exist, an error
message is output.
Channel change
Only one channel/program at a time can be simulated in the simulation, i.e. direct
synchronization across channels is not possible.
Using the "Channel/spindle" softkey, programs can be assigned to specific
channels to be executed one after another.
The preset channel is channel 1 or the first channel in the simulation. Before
programs are selected, the simulation is switched to the channel for the current
program.
MD 11280 WPD_INI_MODE = 1:
The system checks whether a TOA file with the current program name exists. If so,
• the tools are cleared
• the TOA file is loaded into the active file system for the simulation and
• (if tool management is active), the file TO_ADDON.INI (in HMI_ADV\DP\SIM) is
loaded into the simulation and executed.
All files (RPA, GUD, SEA, UFR, PRO, CEC, TMA) with the part program names
are then loaded into the passive file system in the simulation.
The programs in the channel/spindle list are executed one at a time in the specified
sequence with each "NC start" of the simulation; with each program change the
graphics status is retained as a blank specification for the next program. Hidden
programs are skipped.
After the last program the graphic is cleared – after prompting – and the simulation
starts again with the first program.
