WHAT IS OFS MONITOR?
An OFS console has the capability to monitor a number of line components and graphically show the impact of component faults on overall line efficiency.
In a single, intuitive view, OFSLive compares overall line performance against dynamic efficiency targets, current shift and product performance as well as showing operator diagnosis and commentary for stops.
OFS then automatically displays the status of the monitored line components at the time of the stop.
A Monitor Example:
The graphic example plots the overall line speed (blue line) against the target for the current product (green line). The solid green bars illustrate when the line is running and it is easy to see from the red bars when and where the line has come to a stop.
The purple bar below the red bar represents the “Straw Applicator” component of this line. OFSLive clearly shows that the straw applicator failed a few minutes before the overall line stopped. Shortly after the straw applicator fails and buffers fill up, other downstream components (brown bar in this case) also fail.
Once this was visualised, operations implemented a procedure to ensure that the straw applicator always had enough material to continue running, with engineering increasing the accumulation buffer prior to the straw applicator to ensure the line can keep running. A contingency plan if this does not solve the issue is to install a second straw applicator, thereby alleviating the constraint altogether.

IN REAL TIME:
Operators can see when an upstream or downstream component has failed and take appropriate action before the whole line needs to stop. Furthermore, accuracy of operator information, diagnosis and commentary at the time of data collection is much enhanced with the visual benefits of component monitoring.
IN PROJECTS AND CAMPAIGNS:
Operations, engineering and continuous improvement personnel use the OFSLive visual tools to review and tune line performance.
