The Only Constant is Change: Challenges in Modern Automation Engineering
In the past few decades, heavy processing industries have made significant strides in enhancing mechanical reliability and automation to extend the intervals between unplanned shutdowns. Initiatives like Reliability-Centered Maintenance, Risk-Based Inspections and advancements in rotating equipment have notably doubled or even tripled industrial plant operational uptime.
However, alongside these advancements, today's automation systems have evolved into intricate networks with thousands of interconnected measurements, integrated applications and unprecedented levels of interoperability. While this complexity brings efficiency gains, it also introduces new challenges, particularly in managing system configurations amid continuous changes. In this blog I discuss several of the challenges automation engineers commonly face in managing these complicated systems and outline a possible solution to help overcome them.
Challenges Faced by Modern Automation Engineers
Conditions for optimum operations change frequently to meet production, environmental and safety requirements. Changes such as production rate and product composition often require modifications to the automation system. Automation engineers are always looking for opportunities to help operations personnel achieve their production goals. The unlimited possibilities in configuring an automation system have enabled continuous improvement without the need for new equipment. It has also brought about a considerable challenge: managing change.
Interoperability Challenges
The integration of technologies such as Modbus, OPC, HART and Ethernet-based control systems facilitate operational efficiencies but also introduce complexities:
-
Changes in one system often affect others directly or indirectly.
-
Cross-disciplinary impacts within automation organizations become common.
-
Limited self-documentation tools fail to capture comprehensive inter-system integration, leading to risks during change management.
Change Detection and Management
Daily changes in automation systems are the norm, but the majority are unmanaged and undocumented:
-
Unauthorized changes can go undetected, posing significant operational risks.
-
Unconscious errors during configuration changes are challenging to verify and rectify.
-
Inadequate Management of Change (MOC) processes contribute to industrial accidents and vulnerabilities.
System Reliability and Configuration Integrity
The flexibility of modern automation systems enables extensive customization but also introduces certain complexities such as configuration errors and interconnectivity issues. These include unintended changes to critical alarm configurations which can lead to costly production disruptions.
Introducing PAS Automation Integrity™
To address these challenges effectively, PAS Automation Integrity™ emerges as a crucial enterprise application for industrial plants. The solution’s strength lies in its ability to aggregate and contextualize information. This feature enables the efficient management of configuration databases, programs and user interfaces, simplifying system information. Additionally, the software automates document management and tracking - a role that ensures all changes are effectively recorded. This feature tracks configuration modifications, bolstering both reliability and safety. PAS Automation Integrity also enhances safety and security by identifying unauthorized changes, detecting configuration defects and enhancing compliance with relevant safety standards.
Lastly, the enterprise application improves plant performance. By reducing errors and automating manual processes, it greatly enhances productivity. The solution significantly lowers the level of effort required for documentation. Considering these features, PAS Automation Integrity is a vital tool for industrial plants looking to improve their overall performance and safety.
