Integration with the ICSS
As soon as the process model has been signed off in the MAT, the OTS supplier can start integrating it with the ICSS. But waiting until this point to get the integration going will result in the loss of very precious time, and integration with the ICSS should be considered from the point where modelers are building the process model.
Getting the ICSS hardware set up and the ICSS databases loaded into it will take weeks, so this needs to start well before the MAT finishes, with some contingency plans to cater for unknowns.
There are two ways to integrate the process model with the ICSS:
- Cold integration – Integrate the ICSS with a shutdown case of the process model.
- Hot integration – Integrate the ICSS with a full production case of the process model.
Each type of integration has advantages and disadvantages. In cold integration, the integration engineer integrates all I/O points in one go as the process is shut down,...
