FX Series Programmable Controllers Execution Times And Instructional Hierarchy 7
7-12
The following table identifies an 'overlapping
relationship'. This means the secondary program
construction starts within the complete operating
boundaries of the primary program construction but
finishes outside of the primary construction, e.g.:
À Enters a state as if the DI instruction was missing. An error is not generated.
 The first occurrence of either an FEND or the END instruction takes priority. This would
then end the program scan prematurely.
® The sequence will not process as expected, e.g.:
