Operating Time Monitor Function
Errors in machine operation can be detected by measuring
the time interval between output and input.
The Slave can perform high-speed measurement of the interval
between the time an output is turned ON by a specified bit and the
time an input is turned ON. It is possible to read this measurement
result (between 2 and 65,535 ms) using the Configurator or explicit
message communications. This feature contributes to preventive
maintenance by allowing the detection of mechanical deteriora-
tion, such as air leaks in cylinders. A threshold value can also be
set in the Slave so that a flag turns ON when the time becomes
longer than a set time.
■
Contact Operation Counter Function
Provides notification of maintenance timing for I/O devices,
such as switches and actuators.
This function provides notification of maintenance timing for input
and output devices, such as switches and actuators.
■
Energized Time Monitor Function
Every six minutes the Slave records the total energized time of, for
example, a motor. This record can be read using the Configurator
or explicit message communications.
