The controller manages start/stop commands, load/unload signals, and VFD speed references through hardwired I/O and network communication—ensuring fail-safe operation even during network interruptions. EtherNet/IP Native Rockwell protocol for high-speed PLC communication Modbus TCP/RTU Universal industrial protocol for legacy device integration BACnet Building automation protocol for BMS integration OPC-UA Secure, platform-independent data exchange standard ### Supported Equipment Rotary Screw Compressors Centrifugal Compressors Reciprocating Compressors Refrigerated Dryers Desiccant Dryers Smart Electric Meters (kW/kWh) Thermal Mass Flow Meters (CFM) Dew Point Sensors (-40°F to +50°F) Nitrogen Generation (PSA/Membrane) VFD Speed & Current Feedback Pressure Transducers Temperature Sensors (RTD/Thermocouple) ### Universal OEM Compatibility Atlas Copco Ingersoll Rand Sullair Kaeser Quincy Gardner Denver Kaishan Hitachi Kobelco FS-Elliott Cameron / Joy Sullivan-Palatek ## Controller & Operator Interface Allen-Bradley PLC with PanelView HMI display—all components are replaceable and industry-standard. The same familiar interface is used across every compressor type, so staff never have to learn a proprietary system. ### Universal Load Sharing Our controller load-shares any combination of compressor types and control mechanisms in a single unified system. Reciprocating Compressors Rotary Screw Compressors Centrifugal Compressors Turn Valves Lift Valves Spiral Valves Inlet Guide Vanes Variable Speed Drives (VSD) ### Graphical Operator Interface The PanelView gives operators a real-time window into compressor operation with consistent displays across all equipment types. Compressor status — online, loaded, or standby mode Local or remote control indication Separate alarm & trip indicators with specific failure annunciation Live pressure trend display ### Connectivity - Built-in Ethernet connection & web interface - SCADA & BAS integration via optional interfaces - Slave panels for multi-location systems over plant network - Easy connection to existing OEM controllers ### Additional Monitoring kW & Power Factor Flow Measurement Dew Point Data Logger NEMA Enclosure — H 20″ × W 20″ × D 8″ 60 lbs — includes power supply, terminal strip & microprocessor System pressure transducer included ## Intelligent Sequencing & Analytics Our analytics engine ingests historical and real-time PLC data to continuously optimize compressor staging decisions, delivering measurable energy savings and operational visibility. ### Event-Driven Pre-Staging The sequencer accepts input signals from production lines or other significant events about to start, pre-staging enough compressor capacity to prevent pressure sag when demand ramps up. ### Efficiency Mapping Each compressor's specific power curve (kW/100 CFM) is modeled across its full operating range to always select the most efficient combination. ### Anomaly Detection Intelligent baseline models flag deviations in discharge temperature, pressure differential, and power consumption—identifying leaks, fouling, and bearing wear before failure. ### Run-Hour Equalization Intelligent rotation algorithms balance cumulative run hours across the fleet while respecting maintenance windows and lead/lag preferences. ### Adaptive Sequencing Machine learning continuously refines sequencing logic based on seasonal patterns, shift schedules, and process demand variability unique to your facility. ### Predictive Maintenance Trending data on temperatures, pressures, and motor currents builds degradation models that predict maintenance needs weeks in advance. ## Cloud Analytics Dashboard All PLC data streams to our cloud analytics platform, delivering KPIs like specific power (kW/100 CFM), system efficiency ratio, leak load percentage, and cost-per-unit metrics. Data-driven insights adapt to each facility's unique demand profile—providing actionable information that drives 15–30% energy reductions with continuous improvement over time.

Used for high-speed, deterministic communication with Allen-Bradley I/O, drives, and any EtherNet/IP-enabled compressor controller (including modern Atlas Copco, Ingersoll Rand, and Gardner Denver platforms). ### Modbus TCP & RTU The universal compressor language. Virtually every rotary-screw, centrifugal, and reciprocating OEM exposes load/unload, run, alarm, and metering data over Modbus TCP (Ethernet) or Modbus RTU (RS-485) — the sequencer reads and writes both. ### BACnet MS/TP & IP The standard for building automation. The sequencer publishes compressor status, kW, and pressure as BACnet objects so the facility's BMS — Siemens Desigo, Honeywell, Johnson Controls, Trane — can trend and alarm compressed air alongside HVAC. ### OPC-UA The modern, secure standard for IIoT and enterprise integration. OPC-UA lets MES, historian, and ESG-reporting platforms subscribe to the same real-time data stream feeding the cloud analytics dashboard. ## Compatible Compressor OEMs Because the platform is built on open protocols rather than a single manufacturer's proprietary network, it sequences mixed fleets — fixed-speed, VFD, rotary-screw, and centrifugal — from any combination of vendors in a single unified control system. ### Atlas Copco GA, ZR, ZH series via Elektronikon / Modbus / EtherNet-IP ### Ingersoll Rand Sierra, R-Series, Centac centrifugals via Xe / X-Series / Modbus ### Sullair LS, ShopTek, TS-Series via Supervisor / Modbus RTU ### Kaeser ASD, BSD, CSD, DSD series via Sigma Control / Modbus / Profibus gateway ### Quincy QSI, QGV, QGS via Q-Master / Modbus ### Gardner Denver VST, EnviroAire, L-Series via GD Pilot / Modbus / EtherNet-IP ### Kaishan KRSP and KRSP2 lines via Modbus RTU/TCP Don't see your OEM? If the compressor exposes a serial or Ethernet control port, our engineers can integrate it — that's the entire point of using a vendor-neutral PLC backbone. ## Sensing & Metering Stack Sequencing decisions are only as good as the data feeding them. Every installation includes an engineered sensing package so the PLC sees the same real-time picture our analytics team does. ### Electric Power Metering Revenue-grade kW, kWh, and power-factor metering on every compressor — the basis for specific-power (kW/100 CFM) trending and IPMVP Option B verification. ### Thermal Mass Flow Insertion-style SCFM flow meters on each header give the sequencer true demand data, not just pressure-derived approximations, and enable accurate leak-load quantification during off-shifts. ### Pressure Transducers High-resolution transducers at the discharge header, dryer outlet, and critical point of use let the PLC hold a ±2 PSI control band where cascading controls held ±10 PSI. ### Dew Point & Temperature Dew-point sensors verify dryer performance; discharge, oil, and ambient temperatures feed predictive-maintenance alarms before a compressor trips on high temperature. ## Cloud Monitoring & Remote Capabilities Every PLC ships connected to the Emergent Energy Solutions cloud analytics platform. Real-time data — kW per compressor, header pressure, SCFM flow, dew point, run hours, alarm state — is sampled at one-second resolution and surfaced through a browser-based dashboard accessible from any device. Customers see live performance; our engineers see the same view and proactively flag drift before it becomes a downtime event. Remote capabilities include encrypted VPN access for secure tuning and firmware updates, configurable email and SMS alarms for trip events or efficiency excursions, and exportable reports for utility rebate documentation, ISO 50001 energy reviews, and Scope 2 carbon accounting. Because the historian lives in the cloud, there's no plant-side server to maintain. The same cloud layer enables run-hour equalization across the fleet, automated weekly performance summaries, and benchmark comparisons against our installed base of 100+ industrial facilities — turning the sequencer from a standalone controller into a continuously improving energy-management system. ## Related Reading [Technology ### Remote Monitoring & Cloud-Connected Sequencers ](/blog/remote-monitoring-cloud-sequencers)[Technology ### Common Sequencer Installation Mistakes to Avoid ](/blog/common-sequencer-installation-mistakes)[Energy Savings ### Demand-Side Management Through Sequencing ](/blog/demand-side-management-sequencing) [![Emergent Energy Solutions](/assets/footer-logo-DhJESLe2.png)](/) Emergent Energy Solutions, LLC is a Philadelphia-based company specializing in energy monitoring, compressed air optimization, and sustainability consulting for commercial and industrial facilities. #### Services - [Consultative Services](https://www.emergentenergy.us/consultative-services) - [Energy Sub-Metering](https://www.emergentenergy.us/energy-metering-amr) - [Industries & Case Studies](https://www.emergentenergy.us/Turnkey-Solutions) - [Compressed Air Blog](/blog) #### Resources - [Compressed Air Challenge®](https://www.compressedairchallenge.org) - [DOE Resources](https://www.energy.gov/eere/amo/compressed-air-systems) - [Energy Blog](https://www.emergentenergy.us/blogs/energy-submetering) #### Contact - 831 Lincoln Ave Unit D-10 West Chester, PA 19380 - [215-645-7141](tel:2156457141) - [sales@emergentenergy.us](mailto:sales@emergentenergy.us) #### Part of the Emergent Energy family [Emergent Energy Solutions — full-spectrum energy efficiency services](https://emergentenergy.us/)[circuit-level monitoring behind every sequencing project](https://emergentmetering.com/)[qualify compressed-air savings for utility rebates & Tier II AECs](https://pasrecs.com/) © 2026 Emergent Energy Solutions, LLC.
