Block Programming Instructions Section 3-32
The following table shown the relationship between the operand bits and block
program execution.
As shown in this example, WAIT(805) and WAIT(805) NOT can be used to
progressively execute steps within a block program.
Note No block programming instructions will be executed while the input condition
for WAIT(805) is OFF. The other block programming instructions will be exe-
cuted again after the input condition for WAIT(805) turns ON. If, however,
online editing is executed for a task containing a block program, the wait sta-
tus created by WAIT(805) will be cleared and the block program will be exe-
cuted again from the beginning.
