Use the keyboard to enter one or more blocks in the MDA... input window.
Press the INPUT key at the end of each block. An end of block character (L F )
is generated automatically and the cursor moves to the next line.
You will find a complete description of the operator actions for editing in the
section entitled "Programming".
When you press NC START, the program blocks are processed. If the program
modification clear (CLR) is active, all the blocks are cleared after processing,
or the MDA blocks are cleared after pressing the RESET key.
If the program modification clear (CLR) is not active, you can use the
DELETE BLOCKS softkey to clear the program blocks.
You can interrupt program execution in one of the following ways:
• Setting the DSB, BRK and PST program modifications
• Pressing NC STOP
• Pressing FEED STOP
The program is restarted by pressing
• NC START
• FEED START.
If you press the RESET key, execution is terminated. A RESET is also
generated by changing the mode, i.e. execution is interrupted. Pressing NC
START starts the program from the beginning. If clear (CLR) is active,
RESET deletes the MDA blocks.
While the program is being executed, the display "Program running" appears in
the frame of the mode field.
The entire programming scope can be used without restriction.
If an MDA program is interrupted by decode single block (DSB) or program
step (PST), you can edit without restrictions after the breakpoint block. When
you press NC START, execution begins at the breakpoint position.
