Description
When the input conditions
turn ON, execution of the
program jumps to the
specified step number (01
to 99) of the Step Ladder
Program block at the
specified block address
(400 to 499).
Á
To specify a jump to the
self step number, set the
block address to 000.
Á
When a jump is made to
another Step Ladder
Program block, run/stop
command S1 of the
source block
automatically turns 0
(OFF), and run/stop
command S1 of the
destination block turns 1
(ON).
This is the timer (setting
range: 0 to 9999 sec) for
moving between steps. It
has no input conditions.
(STEP TIMER is placed in
the same line as the STEP
command.)
Operation is started when
program execution moves to
the line containing the STEP
command.
When the time set by STEP
TIMER is reached, the
program execution moves to
the next step.
Note: "Input condition
commands" are
given top priority.
This is the timer (setting
range: 0 to 9999 sec) for
monitoring steps. It has no
input conditions.
(ALARM TIMER is placed in
the same line as the STEP
command.)
Operation is started when
program execution moves to
the line containing the STEP
command.
When the time set by
ALARM TIMER is reached,
the Step Timer Completion
flag (step congestion
indicator) turns 1 (ON).
At this time, the step is held
at the current values.
