Rung Descriptions (Figure G.2)
Rung 1
Each time TON 031 is done, the sequencer instruction outputs the next step.
These steps were described previously. The sequencer done bit is set when
the sequencer reaches its last step.
SEQ LENGTH: Number of steps (8 for this example).
WORDS PER STEP: 1 (for this example).
FILE: Address range of steps (037-046 for this example).
MASK: Select any available address and set all bits equal to 1 (035 for
this example).
OUTPUT WORD: I/O address at which the output modules for the DL20
are located (010 for this example).
