Course Curriculum — 8 Modules
Industrial Automation Architecture — Sensors to Control Hierarchy
This module establishes the complete industrial automation architecture — the system-level map that every subsequent module locates itself within. Field-level components are covered first: sensor types and signal characteristics for the process variables measured across industrial facilities — temperature, pressure, flow, and level — alongside actuator types including control valves, motor starters, and variable speed drives, and the 4–20 mA and digital signal conventions that connect them to controllers. Controller-level technology is addressed comparatively: PLCs as the discrete and machine control workhorse, RTUs as the remote telemetry solution for geographically distributed assets such as pipelines and wellheads, and the selection logic between them. Supervisory and visualisation layers are introduced: HMIs as the local operator window, SCADA as the wide-area supervisory platform, and DCS as the integrated process control architecture used in continuous process plants — with the practical differences between SCADA and DCS explained through the facility types each dominates. The ISA-95 automation pyramid provides the organising framework: field, control, supervisory, MES, and ERP levels, and the data flows between them. GCC industry context runs throughout: the automation architectures deployed across Saudi Aramco gas plants, ADNOC processing facilities, SABIC petrochemical complexes, and the water and power utilities operated by DEWA, SEC, and Kahramaa across the region.
PLC Fundamentals — I/O, Ladder Logic & Troubleshooting
This module builds the vendor-neutral PLC programming foundation that the Siemens-specific workflow module extends — the logic concepts that transfer across every PLC platform an engineer will encounter. The PLC scan cycle is covered first as the execution model that explains all PLC behaviour: input reading, program execution, and output writing, and the timing implications this cycle has for fast events and program structure. I/O addressing is treated in depth: digital and analog input and output types, addressing conventions, and the signal scaling that converts a raw analog value into an engineering-unit process variable. Ladder logic programming is developed systematically: contacts, coils, and rung logic for start-stop circuits, seal-in (latching) logic, and interlock patterns — the foundational circuits that make up the majority of real machine control programs. Function block programming is introduced per IEC 61131-3 as the structured alternative to ladder for reusable logic, alongside timers (on-delay, off-delay) and counters (up, down) applied to practical sequencing problems such as conveyor control and pump alternation. Troubleshooting closes the module as a systematic discipline: using online monitoring to trace logic execution, distinguishing field device faults from logic faults from I/O module faults, and the structured fault-finding methodology that maintenance engineers and technicians apply on live production systems across GCC industrial facilities.
Siemens PLC Workflow — TIA Portal Configuration, Programming & Simulation
With vendor-neutral fundamentals established, this module applies them within Siemens TIA Portal — the integrated engineering environment for the S7-1200 and S7-1500 controller families widely deployed across GCC industrial facilities. TIA Portal project structure is covered from creation forward: the project tree, device and network views, and the integrated engineering concept that places PLC, HMI, and drive configuration within a single environment. Hardware configuration is treated in depth: selecting and configuring CPU and I/O modules for the S7-1200 and S7-1500 platforms, assigning I/O addresses, and the device properties that govern controller behaviour. Programming practice develops within the TIA Portal editor set: ladder (LAD) and function block diagram (FBD) programming, organisation blocks and the cyclic execution model, function blocks and data blocks as the structuring mechanism for reusable, maintainable code, and the tag table discipline that keeps a growing program navigable. Simulation with PLCSIM is covered as the testing methodology that allows logic verification without physical hardware: loading a program into the simulator, forcing inputs, and observing logic behaviour before any connection to a real controller. The module closes with commissioning basics: downloading to hardware, going online, monitor and modify functions, and the safe practices that govern online changes to a controller — establishing the workflow discipline the testing and commissioning module later formalises at system level.
SCADA Design — Tags, Graphics, Alarms & Operator Interface
This module develops the SCADA and HMI design competency that turns raw controller data into an operator interface a plant can actually be run from — treated as a design discipline with recognised standards rather than an exercise in screen decoration. Tag database design is covered as the foundation: tag naming conventions, tag types, controller address mapping, and the scaling and engineering unit configuration that determines data quality throughout the SCADA layer. Graphics design is addressed against ISA-101 HMI design principles: display hierarchy from plant overview through unit and detail displays, the high-performance HMI philosophy of muted backgrounds with colour reserved for abnormal conditions, and the navigation design that lets an operator reach any display within a consistent, predictable structure. Alarm design is treated with the seriousness the topic demands: alarm philosophy per ISA-18.2, alarm prioritisation, and the alarm rationalisation discipline that prevents the alarm flooding that has contributed to real industrial incidents. Trend configuration and historian concepts are covered: real-time and historical trending, data logging strategy, and the historian architecture that supports analysis and reporting across the enterprise. User permissions and security close the module: role-based access, operator versus engineer versus administrator privilege levels, and audit trail practice — the operational security baseline expected on SCADA systems across GCC utilities and oil and gas facilities operated by organisations such as DEWA, Kahramaa, and Saudi Aramco.
DCS and Process Control — Loops, PID, Interlocks & Sequences
This module addresses the process control discipline at the heart of DCS platforms — the continuous control concepts that distinguish process plant automation from the discrete logic covered in the PLC modules. Control loop fundamentals are established first: the measurement, controller, and final control element structure of a feedback loop, open-loop versus closed-loop behaviour, and the process dynamics — dead time, lag, and gain — that determine how a loop responds to control action. PID control receives dedicated depth: the proportional, integral, and derivative terms explained through their individual effect on loop response, common tuning approaches and the practical symptoms of poorly tuned loops, and the enhancement structures — cascade control for improved disturbance rejection, ratio control for blending applications, and feedforward for measurable disturbances — used across real process units. Interlock logic is covered as the protective layer: process interlocks, permissive logic, and the relationship between control-level interlocks and the independent safety instrumented systems addressed conceptually per IEC 61511. Sequential control addresses the automation of procedural operations: sequence design, step and transition logic, and the batch control concepts of ISA-88 contrasted with continuous process control — grounding the batch-versus-continuous distinction in the facility types each dominates across the GCC, from SABIC and Borouge polymer batch operations to the continuous gas processing and refining units operated by Saudi Aramco and ADNOC.
Industrial Communication — Fieldbus, Ethernet & Cybersecurity Basics
Industrial communication is the connective layer that makes the automation architecture of Module 01 function as a system, and this module covers the protocols and security practices that govern it. Modbus is covered first as the most widely encountered legacy protocol: RTU and TCP variants, the master-slave register model, and the addressing and function code logic that makes Modbus the common denominator for integrating devices across vendor boundaries. The Siemens-ecosystem protocols follow: Profibus DP as the established fieldbus for distributed I/O and drives, and Profinet as its industrial Ethernet successor, with the device classes, network topologies, and diagnostic capabilities that differentiate them. Ethernet/IP is addressed as the dominant protocol of the Rockwell ecosystem, completing coverage of the three protocol families a GCC automation professional is most likely to encounter across mixed-vendor facilities. OPC UA is treated as the vendor-neutral integration layer: the client-server and information modelling concepts that make OPC UA the standard bridge between control systems and the SCADA, historian, and enterprise layers above them. Cybersecurity basics close the module with the weight the topic now carries: the IT/OT distinction, network segmentation and the zone-and-conduit model of IEC 62443, hardening basics for controllers and engineering workstations, and the OT security awareness increasingly mandated on critical infrastructure across the GCC — reflecting regional frameworks such as Saudi Arabia's NCA OT cybersecurity controls and the UAE's critical infrastructure protection requirements.
Testing and Commissioning — FAT/SAT, Loop Checks & Handover
An automation system that has been programmed is not an automation system that has been proven — this module covers the structured testing and commissioning discipline that takes a control system from engineering completion to operational handover. Factory acceptance testing (FAT) is covered as the first formal verification gate: FAT procedure development, test case structure derived from the functional design specification, simulation-based logic verification, punch list management, and the client witnessing conventions that govern FAT execution on GCC EPC-delivered automation projects. Site acceptance testing (SAT) addresses the verification that follows installation: the scope differences between FAT and SAT, and the site conditions — real field wiring, actual network infrastructure, live process interfaces — that SAT uniquely verifies. Loop checking is treated as the systematic backbone of instrumentation commissioning: end-to-end verification from field instrument through marshalling and I/O to the controller and operator display, loop folder documentation, and the sign-off discipline that builds the commissioning record. Alarm and interlock testing receives dedicated coverage: function testing of every configured alarm and protective interlock against the cause-and-effect documentation, and the criticality-based prioritisation of protective function testing. The module closes with documentation and handover: as-built documentation requirements, operator and maintenance training obligations, and the structured handover package — test records, certificates, and system documentation — expected at completion of automation projects across GCC process and utility facilities.
Capstone Automation Project — Control Logic, SCADA/HMI Screen, Alarms & Trends
The capstone module integrates every layer of the programme into a single end-to-end automation project, structured to mirror a small real-world automation delivery scope. Participants program a complete control logic sequence for a representative process application — a pump station duty-standby sequence or a tank filling and transfer sequence typical of GCC utility and process facilities — applying the ladder and function block programming discipline, TIA Portal workflow, and simulation-based verification developed in earlier modules. The SCADA/HMI component requires participants to design and build an operator screen for their application against the ISA-101 design principles covered in the SCADA module: correct display hierarchy, high-performance graphics conventions, and navigation logic. Alarm configuration is a required deliverable, not an optional addition: participants configure a rationalised alarm set with correct prioritisation for their application, alongside trend displays for the key process variables their sequence controls. Verification discipline is exercised deliberately: participants apply a simplified FAT methodology to their own project — structured test cases, simulated fault injection, and documented test results — before final presentation. The capstone concludes with a complete, demonstrable automation package — programmed controller logic, operator screen, alarm and trend configuration, and test documentation — assessed against the professional delivery standard covered across the programme, giving participants a portfolio-ready project that demonstrates practical automation competency to the standard expected by employers across the GCC industrial sector.
