This function can measure and monitor the time between the ON/OFF transi-
tions of two bits. The Unit's starting and ending bits can be selected freely.
The trigger edge (ON→OFF or OFF→ON), and input or output numbers can
be selected freely, providing flexibility when testing. A monitor value can be
set in the Unit to monitor the operating time, and turn ON a warning flag in the
Status Area when the set value is reached. A monitor value can be set in the
Unit, and when the operating time exceeds the monitor value, the Operation
Time Monitor Flag in the Status Area is turned ON. (Bit 2 of the Communica-
tions Unit's Status Flags is turned ON.) The Programming Device can be
used to read the status of the flag.
This example shows how to use the DeviceNet Configurator (version 2.43 or
higher) to set the Operation Time Monitor function.
