Be careful of the following point when using a Unit that can use the operation
time monitor function (i.e., Basic I/O Unit and Expansion Unit, Sensor Con-
nector I/O Terminal, Three-tier Terminal Block, MIL Connector Terminal, or
Screw-less Clamp Terminal).
2. The operating time is recorded as soon as the time has been measured
from when the output changes to ON to when the input changes to ON.
The time until the next output changes to ON, however, continues being
measured internally, and the measurement value will be refreshed if the in-
put changes to ON again before the next output changes to ON. (When an
input occurs during the operation time for a reciprocating operation such
as a cylinder, the measurement for the operating time (outward path) may
be refreshed during the return time (return path).
When an output changes to ON twice consecutively, and is followed by the
input changing to ON, the time is measured from when the second output
changes to ON until the input changes to ON.
