Process control
Instrumentation, PID loops and drives on top of a PLC: the combination process plants, water boards and pharma lines hire for.
One course at a time. The next unlocks when you are halfway through this one.
Step 1InstrumentationBeginnerIndustrial Instrumentation and Process Control
Pressure, level, flow and temperature measurement, switches and sensors, 4-20 mA loops and the calculations, control valves, P&IDs, HART and smart transmitters, calibration, and how instruments meet the PLC, DCS and SCADA.
- Tell open-loop from closed-loop and name every part of a control loop
- Explain absolute, gauge and differential pressure and the instruments that measure them
- Choose a level and a flow technology for a service and say why
Step 2Process controlIntermediatePID Control for PLC Engineers
From on/off to a tuned loop: what P, I and D each do, how to tune by hand and by rule, anti-windup and filtering, and PID inside Allen-Bradley controllers.
- Explain why on/off control cannot hold a setpoint on a fast process
- Wire a loop's transmitter and final element on Micro800 and MicroLogix
- Predict what raising gain, shortening reset or adding rate does to a loop
Step 3DrivesBeginnerVariable Frequency Drives: Wiring, Programming, PLC and Network Control
Power wiring, keypad and terminal control, analog and preset speed references, relay outputs, PLC and Modbus control, fieldbus, safety functions and troubleshooting, on a generic drive and the Schneider ATV320.
- Explain V/F against vector control and VFD against soft starter and servo
- Wire a drive on single-phase or three-phase supply, with shielding and earthing
- Set motor nameplate and basic parameters from the keypad
Step 4PLC programmingBeginnerSiemens TIA Portal
From zero electrical knowledge to a working, simulated S7-1200 program, for nothing.
- Read a ladder rung and predict what the PLC will do with it
- Wire sinking and sourcing sensors to an S7-1200 without guessing
- Build timers, counters and comparators into working interlocks
How the path works
Join the path and its first course is added to your account straight away; the next one is added when you are halfway through, so you never face a pile of unstarted courses. Each has its own progress, notes and final. Take them in the order shown: each assumes the one before. Each course has one assessment: a final of 15 questions drawn from every module, pass mark 60%, with 3 attempts and then a 24 hour wait, so the assessment checks that you followed the lessons rather than testing exam nerves.
Questions
- Is the Process control free?
- Yes. Every course in the path is free in full: lessons, notes, practice tasks and assessments. Joining the path adds all of them to your account in one step. The only paid item is the optional EDWartens Certificate of Completion for each course.
- In what order should I take the courses?
- In the order listed: each course assumes the one before it. Every course keeps its own progress, final and certificate, so you can also take one on its own.
- Do I get one certificate for the whole path?
- Certificates are per course, issued when you pass that course's final assessment and bought only if you want them. Finishing every course in a path gives you one certificate per course.
