Capturing inputs from various instruments

[Former Member]

Dear Experts,

We are into power generation business & there is  a requirement for us for the following 

In the plants there are various types of instruments(pressure gauge,sensors etc.) used to operate the plants for various functionality. Requirement is to capture the readings of all those instruments & based on this inputs perform plant maintenance activities. However since the number of instruments are likely to be more in numbers & there type & make, developing module pool screens for each of them is a very time consuming task. Also the types of instruments would vary based on the type of plants they used.

The requirement is to capture this instruments readings, store them & retrieve them when required(display in form/screens for later edit & reference) Also if this readings are found abnormal then trigger notification,or recalibrate or edit those readings etc.

What would be the best possible solution for designing the above requirement.What is the best practice across the industry that can be
utilised here for development. Since huge database tables & heavy customising is required how can the same be minimised maintaining uniformity.

Can adobe forms be used for such types of development & if so then still underlying database design efforts are still required & data retrieval & edit would be another issue.Pls. advice & suggest best solution.

Hi,

Here, the instruments that you are talking about, are they analog or digital ? How are you planning to get the real time data into ABAP ?

Generally industries use both analog and digital instruments and in order to get the real time information into computer readable format they have certain softwares like SCADA, if this is the case then you have to write some logics in the SCADA software to periodically send data to SAP system, this can be handled in SAP using Idocs.

Once the data is obtained into ABAP. You know best how to processes and how to report it back to the user. For better reporting facilities you may use the options from simple ALVs with download facility to Adobe forms with Web dynpro.

The technique that you use to solve the problem will largely depend upon the resources you have and the time frame to carry out the development and also on the purpose for which your customer wants the reports.

Hope it helps you. Thank you.

Hi Kartik ,

Thanks for your reply. The instruments that we are using are of both type analog & digital .Currently the process of obtaining readings from those is done manually on paper (various formats) & also as I said earlier I would like to save the information & retrieve them as and when desired.

As suggested by you creating IDOCS is not possible as the instruments would differ in there own nature & for every instruments creating idocs is as good as doing module pool screens.

Also storing this readings would require several custom tables.As far as reporting is concerned they are secondary & main concern is how to store the same in SAP & trigger notifications.

Hello Deepak,

To have history of each equipment you need to have separate equipment number, plan & inspection order to record the readings for calibration of each equipment.

From Inspaction lot result recordings (calibration order) reading where there is alram (notification ) is needed should have measurement point with prescribed limits as mandatory in system.

Master Inspection characteristics will update inspection lot results & will also generate measurement doucment & if the doument value is exceeding the limit as set in measuremnt point then system will trigger notification.To trigger notification you need to activate exit.

Hi,

You need to maintain measuring points and documents for technical objects and use them for performance based maintenance to generate the call objects as per best practices. In real business the shift engineer/ supervisor can maintain the docs on regular interval basis at the time of shift closing.
