Module Type Packages

Modularization is important to facilitate flexible

manufacturing and to accelerate the construction and

planning of plants. PME enables modular automation

by providing a library of data objects with interfaces that

semantically define the data to be exchanged between

equipment controlled by a PACSystems controller and a

Process Orchestration Layer (POL) per the VDI/VDE/NAMUR

2658 specification. The library is realized as a set of function

blocks each with an OPC UA interface that forms

the data object to be exchanged with the POL. The POL

coordinates the plant level control by issuing commands

and receiving state information by means of the data objects.

PME can export the definition of data objects used by a single

controller target as a Module Type Package (MTP) that can

be imported into a POL such as Emerson’s DeltaV
