Manufacturing Execution Systems
By building our solutions on MES technology which is aligned to the ISA 95 standard, EmsPT is able to deliver Manufacturing Operational Excellence by design in all our solutions.This standard outlines a common terminology and set of information and operations models which define the structure and flow of information between Enterprise and Control Systems.
By following the ISA 95 standards to build activity, functionality and object models, it is possible to define an integrated MES Solution where people, information and their place in the model is understood.The models produced by this exercise can then be ‘plugged in’ to our technology, which follows the same fundamental concept of modelling both plant and data.
Both ISA 95 and the Purdue Reference Model for Control Hierarchy break industrial control and manufacturing into ‘levels’ of operation, placing people, systems and functionality into a number of levels within the operation. By viewing the business as a logically layered structure, and following standardised data exchange protocols information from disparate systems can be integrated with the minimum of effort.
The diagram below summarises the Purdue model for Control Hierarchy, showing that EmsPT and the technology we use occupies the space defined as ‘level 3’.
Our ISA 95 compliant technology enables EmsPT to provide a flexible and modular approach to Enterprise and Control System integration which is expandable, versatile and ultimately simpler to implement and maintain.
Industry best practices and guidelines, as defined by MESA (Manufacturing Enterprise Solutions Association) identify the need to follow these standards, and to understand the Control System and Enterprise integration activities in terms of business layers. Using technology which is built on the ISA 95 standard means that EmsPT solutions are designed and built against the ISA 95 standards ‘out of the box’, and that the Control System and Enterprise interactions must be modelled as per the ISA 95 standards as a function of designing and implementing the system using our technology.
