PID CONTROL LOOP PERFORMANCE MONITORING SOFTWARE
APROMON™ is a software tool that monitors the performance of the control loops in your plant, indicates which loops have priority to be improved, and helps to find out how to improve them. It is a practical, effective, robust and easy to use control loop management tool.
APROMON is a Control Loop Performance Monitoring Tool (CLPM) that is exceptionally fast to set-up and to learn. Be ready in a matter of hours, not days!
APROMON is safe: it does not replace the existing PLC, DCS or SCADA system and does not modify the control system behavior autonomously. Instead, it runs on a separate Windows PC aside, reads the control system data by means of OPC communication, and reports the control loop performance and improvement opportunities to its user.
It has a number of unique advantages:
It has a number of unique advantages:
- It has a unique power to convert the performance of any type of controller into a single "grade" just like the grade given by a professor to his students.
- It has an exceptionally robust oscillation detection algorithm that will detect the true oscillations despite the presence of noise and disturbances.
- It is much faster to set up and easier to learn and use, resulting in a much lower Total Cost of Ownership.
Benefits of using APROMON:
- Improve your plant's profitability. APROMON delivers quantifiable benefits with typical paybacks ranging from a few weeks to a year.
- Increase process stability and safety by identifying and prioritizing ill-tuned loops and malfunctioning actuators or instrumentation.
- Generate only the alerts and regular reports that you desire. Calculates over 25 valuable performance metrics for each control loop and stores them for later analysis and trending.
- Reduce raw material and energy consumption by identifying and remedying oscillating loops
- Increases the efficiency and effectiveness of process control engineers and technicians. APROMON helps them focus on what matters most.
- Benefit from the low total cost of ownership of APROMON thanks to its unmatched ease of use.
Main criteria monitored by APROMON
- Which loops are not controlling well?
- Which loops are oscillating?
- Which loops have matching frequencies?
- Which control valves are not working well?
- What are the contributions of the proportional, integral and derivative actions?
- Which loops need filter adjustment?
- What is the utilization factor of the loops?
- Which loops do the operators intervene most?
- Which loops have instrument signal problems?
- ....
APROMON generates the loop quality alerts and reports that you want
- Alerts by Email
- Export to Excel
- Hourly, shift, daily reports
- Track PID setting changes
Control Loop Performance Analysis made easy
As the next figure shows, the intuitive user interface of APROMON makes it very easy to find out which loops score worst for any given performance criterion: simply look at the column with the performance criterion of interest, and APROMON will sort the loops and show them as tag name followed by score, worst at the top.
APROMON also gives each loop an overall grade score and a short diagnostic message. By sorting on these you can easily identify which loops have the highest priority to get some attention, and the helpful diagnostic message points out what seems to be the issue(s). This makes Apromon a true control quality monitoring and diagnostics tool. In the following figure you will see some examples:
