Programmable logic controllers, ladder logic, SCADA, industrial networks, and ICS security. Four levels from fundamentals to expert.
For controls techs, automation engineers, integrators.
Advanced Electrical Troubleshooting
For the electrical technician
0-10 V DC, 4-20 mA loops, motor control, VFDs, grounding, NEC, and field troubleshooting. Mostly electrical with light PLC awareness.
For industrial electricians, plant maintenance, motor-shop techs.
Data Center Cooling & Pumps
Critical cooling infrastructure
Chillers, CW/CHW pumps, CRAH/CRAC, BAS integration, and N+1/2N redundancy. Vendor-agnostic. Four levels from field tech to commissioning lead.
For data-center mechanical techs, controls specialists, and commissioning engineers.
Large VFDs & Drives
Refrigerator-sized drives, real power quality
Vendor-agnostic large VFDs: parameters, harmonics, dV/dt, common-mode currents, ride-through, and reliability. Four levels from field tech to drives & reliability lead.
For drive techs, commissioning engineers, and reliability leads on large industrial drives.
Industrial Cybersecurity / OT Security
IEC 62443, Purdue model, NIST
Industrial cybersecurity for the plant floor: IEC 62443, Purdue/ISA-95 segmentation, NIST CSF mapped to OT, real-world attack case studies (Stuxnet, Colonial Pipeline), DMZ architecture, jump servers, and patch management in air-gapped environments. Four levels from awareness to IR lead.
For controls techs, plant IT, OT security engineers, and integrators securing ICS.
Instrumentation & Process Control
Loops, calibration, PID, SIS
Field instrumentation and process control: 4-20 mA loops, HART protocol, hands-on calibration procedures, P&ID symbol reading, transmitter ranging (zero/span), control valve sizing, PID tuning, and Safety Instrumented Systems. Four levels from loop tech to process control lead.
For instrument techs, I&E techs, controls engineers, and process control specialists.
Industrial Networking & OPC UA
Ethernet, VLANs, OPC UA, TSN
Industrial Ethernet from cabling to architecture: IP and subnetting, VLANs, QoS, redundancy, industrial protocols, OPC UA, TSN, and OT network design. Four levels from field tech to network architect.
For controls techs, network engineers, integrators, and OT architects.
AS-Interface (ASi) Bus
Sensor/actuator bus, start to finish
Vendor-neutral AS-Interface: two-wire yellow cable, masters and slaves, addressing, profiles, diagnostics, ASi Safety at Work, and gateway integration. All four levels are free.
For maintenance techs, controls techs, and integrators working with ASi networks.
