11.90 3 Operating Sequences
3.2.3 Influencing ”AUTOMATIC” operation
Note:
The ”Single block” (see Section 2.1.1.6) function works in a similar way.
Operating this key activates the ”Single block” function. The
generated signal is active at the end of the (current) block being
processed.
The ”SBL” (Single block) display appears in the first line of the CRT
display.
Operating the ”Program start” key, causes the single block to be
processed.
The following table indicated in which blocks the ”Decoding single block active” signal, or the
”Single block active” signal must be present if a program is to be processed on a block-
by-block basis.
• Blocks which have been ”pre-processed” without the ”Decoding single block” signal
present in the buffer memory - that have not yet been processed - cannot be stopped.
• A ”Decoding single block” can be influenced using ”OVERSTORE” (see Section
3.2.3.2).
