This paper examines the coordination of physically linked packaging lines based on so-called Automation Service Choreographies. For this purpose, an exemplary packaging line is considered, which is automated in a service-based manner according to the module type package (MTP) concept. To coordinate the modules of this line, they exchange relevant system variables by means of direct module-to-module communication. Each module additionally contains module-internal rules that describe how its behavior depends on the incoming information. It is shown that in this way a distributed coordination of the packaging line can be achieved. In addition, a second interface is presented, by which the packaging line as a whole can be integrated into a higher-level system.

The modularization of process plants and their modular automation are innovative concepts to meet increasing demands for flexibility in plant operation. However, previous approaches to support the engineering of such modular plants do not focus on the early phases of requirements elicitation and concept design, although these early phases are crucial for the economic efficiency of the later plant. This paper presents a method for the formalized description of intentions in the early engineering phases of modular process plants. According to this method, plant operators create a formalized model of their intentions and provide it to the module manufacturers in a modularized form. This allows a reduction of effort in the planning and development of the plant. The approach is demonstrated using an oil, gas and water separation process performed by a modular process plant.

Modular Automation offers promising technologies for the process and chemical industry. It meets the requirements for greater flexibility and a shorter development cycle for production facilities by dividing the process into smaller standardized units. Key element of Modular Automation is the module type package (MTP). It represents a standardized and manufacturerindependent description of the automation interface for selfcontained production units, or Process Equipment Assemblies (PEA), and endows the plug-and-produce capability of PEAs. Software solutions to program MTP compatible PEAs are mostly provided by the Programmable Logic Controller (PLC) manufacturers. They are proprietary and bound to certain hardware and even programming languages. Therefore, their suitability for implementation of soft sensors based on data-driven advanced analytics is strongly limited. In this article we present an opensource Python package, MTPPy, designed for rapid prototyping of MTP-capable soft sensors with a focus on AI-based research applications. MTPPy is aimed at the accelerated deployment of soft sensors in the modular plants;thus, closing the gap between the data-driven model development and integration into the production.

Modular process plants are a promising approach to accelerate the engineering of greenfield process plants. This is achieved by the combination of pre-engineered process equipment assemblies (PEAs) with a standardized interface for the integration in process control systems, the module type package (MTP). This standardized interface can be integrated in the engineering process to further improve the potential. In this paper existing standards are used to generate aspects of the MTP. For this purpose, the engineering process of conventional plants is adapted for the engineering of PEAs. Therefore, similarities and potential of the described aspects have been analyzed regarding shared fundamental standards and characterized by their location in the asset life cycle. To describe the interconnections of the different standards, exemplary rules are proposed, which can be used for a transformation.

The upcoming challenges in the process industry demand a high flexibility, shorter product development cycles as well as energy and resource efficient production. Especially, energy efficiency of process plants is of substantial importance with regard to the high energy consumption in the process industry. With the introduction of modules and modular plants, the industry tries to overcome these challenges. However, an energy efficient production requires the identification, analysis and utilization of energy potentials. In order to be able to identify energy efficiency potentials in production, the introduction of an energy management system according to ISO 50001 plays a significant role. This paper investigates the extent to which energy management is practiced in the context of modular production and whether there is a need for research. Additionally, a concept is presented how energy management could be implemented in the engineering and operation phases of modular plants.

Modularization is considered as one enabler for flexible and highly reconfigurable process plants. These characteristics are needed to overcome deficiencies regarding market volatility and shorter product innovation cycles. Current standardization activities aim at the specification of module type package (MTP) files as a semantic description of modules for fast and efficient integration into process control systems. To increase the plug and produce character of the approach, online discovery for modules has to be enabled. OPC UA is considered as a suitable industrial communication technology for the communication between modules and process control systems. Therefore, this paper presents an approach for the representation of MTPs in OPC UA in order to enable the online discovery of process modules.
