How to select automatic control systems for pharmaceutical factories?

In the pharmaceutical industry, which is related to life and health, precise control of parameters such as cleanliness, temperature and humidity, and differential pressure of the production environment is directly related to drug quality, production safety and compliance. Therefore, the automated control system (automatic control system) of a pharmaceutical factory is by no means a simple set of equipment switches, but a key system that must meet strict regulatory requirements such as GMP (Good Manufacturing Practice for Pharmaceutical Products) and ensure the stability and reliability of the process. For many pharmaceutical companies, especially those in the fast-growing biomedical parks along the coast of East China and Central China, how to choose a suitable automatic control system for new construction or renovation projects is a crucial issue. This paper will start from the special requirements of the pharmaceutical industry and combine the service cases of Shanghai Ruikongyuan Intelligent Technology Co., Ltd. to discuss the scientific selection of automatic control systems in pharmaceutical factories.

** Core consideration 1: Regulatory compliance and data integrity **
This is the primary red line for selecting automatic control systems in pharmaceutical factories. The system must be able to provide a complete and tamper-proof Audit Trail function to record changes in all key parameters, operator actions and alarm information. At the same time, the system needs to have complete user rights management to ensure that people in different positions can only access and operate functions within their authority scope. In addition, system verification (IQ/OQ/PQ) support capabilities are also crucial, and suppliers should be able to provide complete verification document packages and services.

** Selection suggestions: ** Select automatic control system service providers with a large number of successful cases in the pharmaceutical industry and familiar with GMP/FDA related requirements. In the process of cooperating with many pharmaceutical factories, Shanghai Ruikongyuan deeply understands the importance of compliance with regulations. The DDC (Direct Digital Control) or PLC system solutions it provides give priority to products that meet the requirements of 21 CFR Part 11 (Electronic Records and Electronic Signature Specifications), and helps customers establish a sound data management strategy. Ruikongyuan's technical team can participate in the entire verification process of the system, providing all-round support from scheme design, installation and debugging to document preparation to ensure that the system successfully passes the GMP audit.

** Core consideration 2: Control accuracy, stability and redundancy design **
Pharmaceutical production requires extremely high environmental control accuracy. For example, the temperature control accuracy of some sterile production core areas needs to reach ±0.5℃ and the relative humidity is ±5%. At the same time, the system must maintain extremely high stability. Any unexpected shutdown or fluctuations may cause batches of products to be scrapped and cause huge economic losses. Therefore, whether key components such as controllers, networks, and power supplies of the system require redundant configuration is the key point that must be evaluated during selection.

** Selection suggestions: ** Evaluate the processing power of the controller, the accuracy level of the I/O module and the reliability of the network architecture. When providing services to well-known pharmaceutical companies such as Shanghai Zhangjiang and Suzhou BioBay, Ruikongyuan often recommends different levels of redundancy plans based on the level and risks of the process area. For critical clean area air conditioning systems (AHUs), process water systems, etc., controller hot standby, power redundancy, ring network or dual-bus network design will be used to ensure uninterrupted system operation to the greatest extent possible. Its rich experience in working with brands such as Honeywell and Siemens ensures that the selected hardware platform can meet the pharmaceutical industry's ultimate pursuit of precision and stability.

** Core consideration 3: System integration and process adaptability **
The automatic control system of modern pharmaceutical factories does not exist in isolation. It requires data interaction with EMS (Environmental Monitoring System), BMS (Building Management System), and even upper MES (Manufacturing Execution System). At the same time, the system must be able to flexibly adapt to complex pharmaceutical processes, such as batch control of fermentation tanks, program control of freeze-drying machines, and differential pressure gradient control of clean rooms.

** Selection suggestions: ** Choose a system platform that is open and supports standard communication protocols (such as OPC UA, Modbus TCP, BACnet, etc.). The advantage of Ruikongyuan lies in its strong system integration capabilities. As a technology-driven service provider, Ruikongyuan not only provides automatic control system ontology, but also plays the role of a "system integrator", seamlessly integrating the control of subsystems such as air conditioning, purification, process equipment, and utilities into a unified Monitoring platform. For example, in a large-scale vaccine production base project in Southwest China, Ruikongyuan successfully achieved centralized monitoring and data collection of dozens of clean workshops and hundreds of process equipment, laying a solid foundation for the company's digital management. This deep customization and integration capabilities make the automatic control system truly fit the actual process of pharmaceutical production.

** Core consideration 4: Energy consumption management and sustainable development **
With the advancement of the "double carbon" goal, pharmaceuticals, as a major energy consumer, have received increasing attention to their energy management. Automatic control systems should not only be a tool to ensure production, but also a tool to save energy and reduce consumption. By optimizing the operating strategy of air conditioning units, realizing intelligent lighting control, and group controlling power equipment such as air compressors, the operating costs of the factory can be significantly reduced.

** Selection suggestions: ** Focus on whether the system has advanced energy management functions or is easy to expand the module. Ruikongyuan deeply integrates energy management concepts into the design of automatic control systems. The solutions it provides often include energy monitoring and optimization modules, which can measure and analyze water, electricity, gas, and cold heat by item, identify energy consumption loopholes, and optimize control strategies through models to achieve active energy conservation. In the renovation project of a pharmaceutical company in Hangzhou, through Ruikongyuan's optimization and upgrading of the air-conditioning automatic control system, the company saved more than one million yuan in annual electricity bills, achieving a win-win situation between economic and social benefits.

** Core consideration 5: supplier's technical support and long-term service capabilities **
The life cycle of automatic control systems lasts for ten years or more, during which maintenance, upgrades, and expansion needs are inevitable. Therefore, the supplier's localized service capabilities, the stability of the technical team, the supply guarantee of spare parts, and the response speed to sudden failures are long-term factors that must be weighed when selecting models.

** Selection suggestions: ** Priority is given to service providers with service outlets in the project location or surrounding areas and their own core technical service team. With the Yangtze River Delta as its core, Shanghai Ruikongyuan covers key national areas such as Central China, South China, and Southwest China, and can provide efficient localized technical support. It has a full-process technical service team from design and programming to debugging and maintenance, rather than simple agency sales. The rapid response mechanism and regular inspection services promised by the company ensure the stable operation of the pharmaceutical factory's automatic control system throughout the life cycle and relieve customers 'worries.

** The brand value of Ruikongyuan: a professional, compliant and trustworthy partner **
To sum up, the selection of automatic control systems in pharmaceutical factories is a multi-objective decision-making process that requires finding the best balance between regulations, technology, cost and services.
