8.8.2 Accelerated block search for execution from external
The accelerated block search function allows you to run the part program forward until you
reach the block you require.
Settings
If you activate the "Skip EXCALL" function, then you must set the following general
configuration machine data:
MD51028 $MNS_BLOCK_SEARCH_MODE_MASK
Bit 3 = 1 (33H to 3BH)
For an external main program, a block search without calculation is always a fast block search.
Only the blocks from the search position are loaded.
8.9 Multi-channel support
In the "Machine" operating area, up to any four channels of a mode group can be displayed
side by side. The number of channels is dependent on the display size and resolution of the
operator panel used.
Using the multi-channel editor, for a multi-channel machine, you can open, change or generate
programs simultaneously that are independent of one another from a time perspective. In this
case, the programs involved are displayed next to one another in the editor.
Further, you have the option of simulating the programs before they are actually processed at
your control.
In addition, you can align the programs according to synchronization points.
View options of the operator panel
The operator panel supports the following views:
