    PI and MOS

    panagiotis.perdikis

      Hello

       

       

       

      Has anyone developed an application that is using information from PI regarding MOS (ie. when a MOS was activated) combining it with another database, for example, SQL, to record also other type of information that can come with the MOS activation (such as operator name, reason for MOS, action required, any other custom information).  Can such an application (maybe an excel file) be built utilising only PI to record this information and be able to access it again at a later stage? 

       

       

       

      Thank you

          What is MOS?

              Hello

               

              I am sorry, MOS means Manual Override Switch and in our case it can be used in the refinery, by an operator for example, to override manually a safety switch. This should not be done unless a special reason exists (such as maintenance of the specific area) for safety reasons.  It can be dangerous to override it, because if a problem occurs at the specific area, safety will not kick in  and a disaster (depending on the criticality of the switch) could occur.

                  Event Frames should be able to handle this - this is similar to a Equipment DownTime event where you capture ReasonCodes and other pertinent information.  

                   

                  How often would a MOS event happen per day, per month?

                   

                  What's the time frame in which you need a finished application in production?

                      Thank you for your answer.  

                       

                      A MOS event can happen anytime, but normally not too often, and there should not be that many in the refinery for their own good.  Absolute numbers I do not know, but they are nothing like regular PI tags that change every minute.  There exist a few thousand MOS tags configured in PI, but only a few of them do change.   We have been discussing this for sometime, so it is not that urgent.  Is there a lot of configuration work involved?  Also, I cannot seem to be able to locate this product.

                       

                      Thank you again.
