ProLogix PEMS™ Predictive Emissions Monitoring PLC-Based Industrial Strength Systems ProLogix PEMS™ is a full-featured, predictive emissions monitoring software system that meets EPA Performance Specification 16 (PS16). Owners and operators can use ProLogix PEMS™ to monitor emissions from boilers, turbines and SI or CI engines. ProLogix PEMS™ calculates pollutant emissions with CEMS-level accuracy, eliminating the need for calibration gases and hardware preventative maintenance. The results are low operating costs and increasing reliability. The results are low operating costs and increasing reliability. ProLogix PEMS™ delivers real-time emissions data over your Ethernet/IP networks for the highest system visibility available.
ProLogix PEMS™ provides a software monitoring solution for your emissions compliance and process measurements of combustion sources under 40 CFR 60 and 40 CFR 75 Appendix E. AMP-Cherokee offers PEMS data monitoring and maintenance plans that include RATA and quarterly RAA tests for maximum system reliability and optimal cost effectiveness.
ProLogix PEMS™ Advantages:
• PLC-based system eliminates PC server security and maintenance requirements

ProLogix PEMS™ uses a statistical model to provide real-time emissions data from a wide range of operating input parameters with CEMS-level accuracy and reliability. ProLogix PEMS™ includes system health, sensor validation, and real time and historical displays that are integrated within the existing DAS or a DAS upgrade.
Data Redundancy. Data Distribution.
With ProLogix PEMS™, data redundancy is provided at the PLC prior to distribution to Ethernet/IP-based networks. Data transfers that are interrupted by network disconnections can be restored to all databases.
Remote Operation. Alarms and Notification.
ProLogix PEMS™ monitors system health status. Email alarms can be configured across your monitoring network. Remote access provides an administrator level operation of controls and troubleshooting tools.
Sensor Validation is a key component of ProLogix PEMS™ – in the event of sensor failure, the PEMS will substitute other sensor data to complete its monitoring tasks to maintain source compliance. ProLogix PEMS™ will signal an alert of the sensor failure to assist in maintaining the required 95% uptime.
CEMS-Level Data Accuracy
The ProLogix PEMS™ model will be able to accurately predict NOx, O2, and CO2 for emissions across all loads and operating scenarios with as few as three sensor inputs or with as many as fifteen sensor inputs. A fourth order polynomial model will be created for each sensor input. In this way, the accuracy of the predictive model can be evaluated for each individual input sensor thereby establishing it’s predictive relative accuracy compared to the other sensor inputs. In addition to developing the PEMS model, AMP-Cherokee will also create a sensor input validation model which will be able confirm the validity of a given sensor input based on it’s relative value in relation to other sensor input values.
After the predictive emissions model and the sensor input validation model have been completed for each boiler, AMP-Cherokee will conduct a bench trial in which historical data is used to evaluate the PEMS model. In this way, engineers can make final adjustments to the PEMS model prior to deployment thereby increasing it’s accuracy.
