Executing MC Programs from the Ladder Program Section 8-2
In this example procedure, task 1 is executed. The following table shows the
equivalent CIO Area control bits and CIO Area words for tasks 2 to 4.
Ladder Programming
Example The following ladder program executes Task 1 in the MC Unit.
Note When executing a positioning operation in the MC program, all of the axes
being used must be servo-locked (Servo-lock ON Flags must be turned ON),
so be sure to add a condition like R4 in the programming example above.
