316 I/O and Event Blocks
For linear axes, the values can be positive, negative, or a combination.
However, the minimum position value must be less than the maximum
position value for the registration event to occur. For rotary axes, both
values must be less than the resultant value derived from dividing the
conversion constant by the unwind constant (both set in Feedback page of
the Configure Axis Use dialog box). The minimum position value can be
greater than the maximum position value for registration windows that
cross the unwind point of the axis.
Wait for Tripped
When you select Wait for Tripped, the program pauses until the
registration event occurs. When it does, the program continues with the
next block. If other tasks are executing (multitasking), the task which
contains this block pauses but the other tasks continue to execute. In this
way, a Wait for Tripped selection in one task does not pause execution of
any other tasks or hang the task dispatcher.
