Execution times for most instructions depend on whether they are executed
with an ON or an OFF execution condition. Exceptions are the ladder diagram
instructions OUT and OUT NOT, which require the same time regardless of
the execution condition. The OFF execution time for an instruction can also
vary depending on the circumstances, i.e., whether it is in an interlocked pro-
gram section and the execution condition for IL is OFF, whether it is between
JMP(04) and JME(05) and the execution condition for JMP(04) is OFF, or
whether it is reset by an OFF execution condition. "RSET," "IL," and "JMP" are
used to indicate these three times.
