Variable 99
IN (Binary Numbers Read Input/Output)
[Function]
Reads the value from the designated I/O port or flag as a binary number, then stores this value in variable
register 99.
WTOF (Waiting for Input/Output Port · Flag OFF)
[Function]
Waits until the designated I/O port or flag turns OFF and does not proceed to the next step. You can use the
time out setting to set a time interval after which I/O waiting will be aborted. The time out setting is in units
of seconds (0.01 ~ 99 sec). When there is a time out setting, the post section turns ON. When there is no time
out setting, the post section is not available.
* Local flags cannot be used in Operand 1.
[Example]
WTOF 25
Wait until input port 25 turns OFF.
WTOF 25
10
Wait until input port 25 turns OFF. Time out occurs after a 10 second interval and
the program proceeds to the next step.
