When it comes to industrial automation, Siemens has long been a trusted name. Their PCS platforms — PCS7 and the newer PCS NEO — are widely used in water and wastewater facilities across Tennessee and beyond. But with two powerful options available, how do you know which one is right for your operation?

At VFTechnical Services in Kingsport, TN, we specialize in both PCS7 and PCS NEO integration. In this article, we’ll break down the differences, highlight the strengths of each, and help you decide which platform best fits your facility’s needs.

What Is PCS7?

PCS7 is Siemens’ established automation platform, known for its reliability and deep integration with industrial processes. It has been the backbone of countless water and wastewater facilities for decades.

• Architecture: Traditional client-server setup.

• Strengths: Proven stability, strong support for legacy systems, and wide industry adoption.

• Use Case: Ideal for facilities that already rely on PCS7 and want to maintain a stable, familiar environment.

Many Tennessee utilities continue to use PCS7 because it provides dependable performance and integrates seamlessly with existing Siemens hardware.

What Is PCS NEO?

PCS NEO is Siemens’ next-generation automation platform, designed for the future of industrial control. It introduces a modern, web-based engineering environment that emphasizes collaboration and scalability.

• Architecture: Cloud-enabled, web-based interface.

• Strengths: Enhanced usability, remote access, and streamlined engineering workflows.

• Use Case: Perfect for facilities looking to modernize, expand, or adopt remote monitoring capabilities.

PCS NEO allows operators to securely manage systems from anywhere, making it especially valuable for utilities that need flexibility and resilience.

Key Differences Between PCS7 and PCS NEO

While both platforms are powerful, they serve different needs.

Which Platform Is Right for You?

Choosing between PCS7 and PCS NEO depends on your facility’s current infrastructure and future goals:

• Choose PCS7 if:

  • You already run PCS7 and want to maintain stability.

  • Your facility relies heavily on legacy Siemens hardware.

  • You prefer a proven, widely supported system.

• Choose PCS NEO if:

  • You’re planning modernization or expansion.
