Standardized communication protocols and interfaces are critical. This ensures seamless integration of new modules and technologies without significant re-engineering or extensive custom programming. Common standards such as OPC UA (Open Platform Communications Unified Architecture) promote interoperability and simplify the expansion process.

Scalable Software:

The control software that orchestrates the FMS needs to be equally scalable. A robust, adaptable Manufacturing Execution System (MES) is essential. It should be capable of handling increased data volumes, managing a larger number of machines and processes, and adapting to new functionalities added through expansion.

Network Infrastructure:

A robust and flexible network infrastructure is paramount. This includes high-bandwidth communication networks, capable of handling real-time data transfer and control signals, even with a substantial increase in the number of connected devices. Redundancy in the network infrastructure is also critical to ensure system uptime and prevent disruptions during expansion.

Key Areas of FMS Extension

FMS extension can take various forms, depending on the manufacturing goals and available resources. Here are some key areas:
