Flexible Project Structure
PME can support one to multiple targets in a single project,
allowing you to scale appropriately based on the application.
Therefore, you can have one project for each controller or
one project for multiple controllers depending on the needs
of the engineering and operations personnel that configure
and maintain the control system.
Versatility
Due to its support of extensive communication protocols
and instructions, PME excels in a variety of industrial
markets, including water and wastewater, oil and gas,
power renewables, mining and marine. Whether an industry
sector requires high-speed loops or advanced regulatory
control for loops where the primary process variable changes
slowly (like many temperature loops), PME has the tools for
effective control and operation.
The Right Programming Languages
PME supports IEC-61131-3 editors including ladder logic,
structured text, and function block diagrams. In addition,
C blocks can be created and merged easily into PME. This
gives you the freedom to use the best language for your
application. The sequence function blocks bring the benefits
of sequential function charts into the function block diagram
editor allowing equipment control and its associated
sequencing to be merged into one editor.
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
