Xsteps + MII

[JLOZANO]

Experts,

Can we take advantage of pi-sheets previously done with Xsteps if we want to implement MII (RDS Batch Manufacturing)?

I´m not sure if we can continue working with reusable xsteps repository.

Which additional tasks should be done in MII pi-sheet template in order to reuse them?

Thanks in advance,

Jorge

Hi Jorge,

the MII RDS solution uses specifically tailored process instruction categories and extracts variable data from those. The communication vehicle for this is the good old PI-PCS interface. If you are using XSteps you can of course also send control recipes via PI-PCS to the MII system.

However no matter which PI-Sheet definition method you use (XSteps or classic process intructions) you need to adapt the MII solution to your specific instructions. There is no built-in "magic" that does this for you.

I hop this helps.

Regards,

Arne

Hi Arne,

sorry but i'm confused.

why somebody wants to implement the MII RDS for batch manufacturing when already using PI-sheet with XSteps? which advantages can be obtained? Or why somebody when evaluating a MES/EBR solution should chose MII RDS instead of PI-sheet?

Reading the solution summary i see:

• Manufacturing Operations Cockpits

• Manufacturing Order List

• Material Identification

• Work Instructions

• Quality Control

• Production Confirmation

• Shift Book

• Monitoring and Logging

• Manufacturing Performance

If I already manage the last 2 thing by OPC and third party software do I really need the rest? Is the pre-built functions are the only reason?

Thanks in advance.

Igor.

Igor,

I agree with you. If a customer is willing to execute everything with online ERP access (which might be a central ERP) then you can do a lot inside the PI Sheet itself.

The reason why this RDS has been developed for a customer was that that customer wanted to have autonomy from a central ERP and therefore they wanted to upload a control recipe to a de-centralized system (MII) and do the execution there. Of course this comes with a trade-off which is much less flexibility.
