(3) Single block processing signal (M4009)
(a) The single block is available in two modes: a mode where a single block is
specified before a program start, and a mode where a single block is
executed at any point during program execution.
The single block processing signal indicates that a single block can be
executed in the mode where a single block is executed at any point during
program execution.
(b) A single block is executed when the single block processing signal is ON.
When the single block processing is OFF, make an SVST start or turn
single block start from OFF to ON to perform continuous operation.
