2-2-2 Accumulated ON (RUN) Time Monitor Function
The E5AR/ER-DRT has accumulated ON (RUN) time monitor functions which
record internally the total time communications power is supplied or the accu-
mulated RUN (control) time. The Unit Maintenance Flag in the General Status
will turn ON if the accumulated time exceeds a set monitor value.
The Detection Mode and Detection Time are set using a Configurator and are
found in the General Setting parameter group.
The ON (RUN) time monitor function can be used as a guide for replacing the
E5AR/ER-DRT Digital Controller.
Measurement unit: 0.1 h
Measurement range: 0 to 429496729.5 h (Stored data: 00000000 to
FFFFFFFF hex).
Note (1) The ON or RUN time is held even when the power is turned OFF.
(2) Both the ON and RUN time monitor functions cannot be used at the same
time for one word.
(3) The accumulated time will not be measured if communications power is
not supplied to the E5AR/ER-DRT.
(4) The E5AR/ER-DRT Digital Controller checks the ON/RUN status of the
target channel approximately every 0.1 h (6 min.).
2-2-3 Operation for Communications Errors
The “Control at Error” specifies the operation to be performed if a DeviceNet
communications error occurs. The Control at Error setting is made using the
Configurator and is found in the Communications Setting parameter group.
