Functionality
The runtime counter for machines and devices function MDSOPT calculates and
presents the accumulated operation time of a machine or device as the output.
The unit of time for accumulation is hour. The function generates a warning and
an alarm when the accumulated operation time exceeds the set limits. It utilizes a
binary input to indicate the active operation condition.
The accumulated operation time is one of the parameters for scheduling a service
on the equipment like motors. It indicates the use of the machine and hence
the mechanical wear and tear. Generally, the equipment manufacturers provide a
maintenance schedule based on the number of hours of service.

Operation principle
The function can be enabled and disabled with the
Operation setting. The
corresponding parameter values are "On" and "Off".
The operation of MDSOPT can be described using a module diagram. All the
modules in the diagram are explained in the next sections.
