What is the use of OR and AND functions in counter based maint plan

Hi

I want to create a counter based maintenance plan...

I entered the measurement reading for the counter, reading is 4000 hrs

IN IP43

I created the counter plan with cycle as 6000 hrs. Once the document reaches 6000 order will be created. While creating the maintenance plan, in the maintenance schedule parameters, i check there is OR and AND functions avaliable...

I know the basic use of both the functions..

But what is the significance in the maintenance plan....

Will it give any effect, between the schedule date and measurement docu entries...

Since i need to maintain like... once the counter reaches 6000 hrs only order should be created.. it should not create once the date as been reached... since due to present condition, i am not running the DG....

Give ur inputs

    Dear Pithan,

    AND & OR functionality can be used to consider the different characteristics. i.e. cycle unit e.g. Hrs & Month.

    If you use AND, once your equipment reaches both Hrs & Month cycle value then only order will be generated.

    If you use OR, either of unit if reaches to cycle value order will be generated.

    It does not give any effect on measuring document. Its seperate task.

    If you want order to be created only after certain Hrs to be reached to cycle value then you may opt for single cycle or strategy cycle.

    Hi

    In Cycle set you define the

    Time-based:

    A task is to be performed every 1 months. The cycle is therefore 1

    months.

    Performance-based:

    A task is to be performed every 1000 Hrs. The cycle is therefore

    1000 Hrs

    If in multiple counter plan using above cycle set---

    In the case of an OR operation, a maintenance call is due which activity come first i.e. Time-based Or Performance-based.if your measurement document posted regularly it is reached 1000 hrs then maintenance call is due on perfomance based inspite of you plan is not complte the 1 month and Vice-versa

    In the case of an AND operation, a maintenance call is only due when all

    the maintenance cycles have finished.

    Regards,

    Rakesh

    Hi,

    This functionality is used for multiple counter plans and mostly with cycle sets.

    Measureent docs created will make cycles applicable for releasing call from ccycle set.And here scheduling parameters And/Or comes into picture.

    You can have multiple cycles for object in different units like kms,hours,rotation cycles etc.

    With OR if any of condition out of these cycles fulfills a maintenance call is triggered.

    But in case of AND all cycle conditions need to be fulfilled then only maintenance call gets triggered.

    regds,
