Process control monitoring and diagnostics is the continuous assessment and performance evaluation of PID control loops, PLC- or DCS-based advanced process controllers (APC), model predictive control (MPC) systems, measuring sensors, and final control elements. PiControl's monitoring and diagnostics software suite, APROMON, PiLogger, and PiLims, gives engineers real-time performance evaluation, accurate fault detection, and streamlined data validation and transfer, so plants can move quickly toward optimal control instead of waiting for a scheduled loop audit to find the problem.
PID loops, APC strategies, and MPC systems degrade quietly. A sticking valve, a drifting sensor, or a controller tuned for conditions that no longer exist rarely trips an alarm; it just costs the plant money every day until someone finds it. Process control monitoring and diagnostics software replaces the wait for a scheduled audit with continuous assessment, so engineers can act quickly and keep loops moving toward optimal control rather than away from it.
Three products cover process control monitoring and diagnostics end to end: continuous AI-based loop performance grading, high-speed data logging for fast troubleshooting, and secure lab-to-DCS/PLC data transfer.
Continuous, AI-based PID/APC/MPC control-loop performance monitoring and diagnostics. APROMON evaluates single, cascade, feedforward, and adaptive loops, automatically calculates and archives 30+ performance criteria for every tag, and assigns performance grades so engineers know which controllers need attention first.
High-speed OPC data logging software for fast, accurate troubleshooting. PiLogger captures process data at high speed to help identify the "First Out" condition during an upset or trip, and the frequently collected raw data it produces supports more accurate system identification and control optimization.
Laboratory information management system with a built-in OPC client for secure lab-to-DCS/PLC data transfer. Where direct data entry into the DCS or PLC isn't feasible for security or policy reasons, PiLims lets lab and process engineers enter data on a Windows server-based computer and transfer it securely into the control system.
Process control monitoring and diagnostics is essential for ensuring the efficiency, safety, and reliability of industrial processes. Here is what it delivers, and which product delivers it.
APROMON uses artificial intelligence to assess the performance of PID and APC loops, evaluating single loops, cascade loops, feedforwards, adaptive loops, and measuring signals.
APROMON automatically calculates and archives over 30+ performance criteria for every tag, in real time.
APROMON assigns performance grades to controllers and dedicated equipment. A higher grade means better performance; a lower grade prompts attention.
PiLogger collects high-speed data so engineers can accurately identify the "First Out" condition during equipment or process-related issues.
PiLims allows data entry on a Windows server-based computer and secure transfer into the DCS or PLC, for laboratory and data-entry scenarios where direct entry isn't feasible.
PiLogger and PiLims both offer testing and training capabilities using standard OPC simulation servers.
Plants use APROMON to continuously monitor and diagnose the performance of PID control loops, DCS/PLC-based advanced process control, and model predictive control systems. Instead of waiting for a scheduled loop audit, engineers see performance grades and 30+ archived criteria per tag, and know exactly which loops need attention.
When equipment or process issues occur, plants turn to PiLogger for fast, accurate high-speed data collection and "First Out" root-cause analysis, and to PiLims for secure lab-to-DCS/PLC data transfer where direct entry isn't feasible. Both products also support engineer and technician training and testing with standard OPC simulation servers.
PiControl's monitoring and diagnostics products run in industrial plants across 40+ countries, continuously grading PID, APC, and MPC loop performance, logging high-speed data for fast troubleshooting, and moving lab data securely into the DCS or PLC.
