MII12.2 and Machine Interaction

[former_member8532]

Hello All,

We are planning to implement SAP XMII 12.2 . I need some help on Machine automation.

In our requirement , MII should be able to send the data (Input parameter for machine)  and get the task completion instruction from machine.

I am not sure how to achieve this . Please suggest.

Regards.

Hi Anshul,

you can also configure PI Tags for each machine parameter at the Nodes of DCS , same PI tags you need to configure in site MII Local Database.

1) Provide a MII UI page to set the machine parameters , allow operators to set according to the requirements

2) Write a BLS to write  parameter values to the PI points.

3) write another BLS to download all those parameter values to the memory of DCS .

this way it should work.

Hi Anshul,

You can achieve this by using Web service interface provided by equipment vendor.

Steps (High Level)

1.create a BLS in MII and make your business logic and use  webservice action block to map the required schema with required value to achieve the task on shop floor.

2. once BLS execute,webservice will return the response/success , capture it and process your response to work in MII or SAP. 

You can also connect to the Historian/Oracle database through Data connector in MII to query the values for machine integration etc.

Go through SAP PCO help to get more details on the MII to machine configuration :

Hope it helps.
