                     WHY DATA CENTRES RELY ON NX-ERA 
PREMIUM PLCS FOR REDUNDANCY & 
RELIABILITY
www.messungautomation.co.in 
Data centres are the online command centres of today's digital economy. Every click, 
login, and transaction routes through them. In such a hyper-connected world, downtime 
isn’t just inconvenient, it’s catastrophic.
Whether running finance systems or hosting cloud apps, data centres can’t afford control 
failures. Hence, businesses invest in redundancy-not just in power or cooling-but also in 
the core of operations: the Programmable Logic Controller (PLC).
That’s where Messung’s NX-ERA Premium PLCs come in-offering unmatched 
scalability, redundancy, and seamless SCADA integration for intelligent, future-ready 
control.

The Challenge: When Control Systems
Become the Weak Link
Power and cooling may be backed up, 
but what about the systems controlling 
them?
Mini or basic PLCs lack the reliability and 
intelligence needed for mission-critical 
operations. A logic error or hardware 
glitch can trigger cascading failures, 
leading to SLA penalties, reputational 
damage, and massive losses.
What’s needed is a Premium PLC
that ensures:
• High-speed, deterministic control
• Hardware and logic-level redundancy
• SCADA and BMS integration

The Solution: NX-ERA Premium PLCs,
Control That Never Sleeps
NX-ERA isn’t just another controller; it’s built to deliver high-availability automation
for critical environments.
1. Built-In Redundancy: Always On
NX-ERA features a dual-CPU setup—one primary, one hot standby. They mirror in real time. If the main 
CPU fails, the backup takes over instantly, ensuring no downtime.
This level of redundancy supports:
• Constant HVAC and cooling
• Live UPS and power distribution control
• Immediate fire detection and suppression response
2. High-Speed PLC for Mission-Critical Tasks
NX-ERA handles complex, distributed control with precision. Event sequencing, real-time I/O updates, 
and deterministic performance make it ideal for anticipating and handling problems before they 
escalate.

Control That Never Sleeps
3. Modular Architecture for Seamless Expansion
Unlike fixed PLC systems, NX-ERA is modular. Add new I/O racks, processors, or server room sensors 
without reconfiguring the system—ideal for growing infrastructure.
4. SCADA Integration: Centralised Control
With MODBUS TCP/IP support, NX-ERA integrates easily with SCADA systems to:
• Monitor system health
• Connect to BMS and EMS
• Enable predictive maintenance
• Manage compliance
This makes your PLC the nerve centre of operations-monitoring,
reporting, and responding in real time.

NX-ERA in Action: Driving Precision Inside Data Centres
Every data centre subsystem-
power, cooling, and safety-
must work in perfect sync. NX-
ERA ensures this harmony with 
microsecond-level control and 
seamless coordination.

NX-ERA in Action: Driving Precision Inside Data Centres
1. Environmental & Cooling Management
Temperature and humidity control are vital to performance and data integrity.
NX-ERA tightly manages:
• CRAC units and air handlers to prevent thermal hotspots
• Chilled water and airflow to match server loads
• Humidity to reduce electrostatic discharge risks
It provides real-time monitoring, logging, and control accuracy essential for audits, AI optimisations, and 
compliance.
2. UPS & Power Synchronisation
NX-ERA manages UPS systems and power distribution, ensuring:
• Smooth transitions during outages
• Load balancing and phase synchronisation
• Zero lag in critical power shifts
In Tier III and Tier IV data centres, this means no performance dip, even during power events.

3. Fire Detection & Suppression
NX-ERA integrates with fire systems to manage:
• Smoke, gas, and temperature sensors
• Alarm systems
• Fire suppression release logic
What’s special? It handles fire emergencies in one zone
while ensuring uninterrupted operation in others.
4. Maintenance Without Downtime
Thanks to redundant architecture:
• Perform firmware upgrades and diagnostics live|
• Backup PLC takes over during maintenance
• No interruptions to ongoing operations
This is redundancy that works in real-time, not just theory.
