Lesson 1: PLC, RTU, Telemetry, and Remote SCADA Architecture
Lesson Overview
This lesson develops practical skills in plc, rtu, telemetry, and remote scada architecture for the PLC, Telemetry, and SCADA Control Systems Training course, with implementation, verification, documentation, and troubleshooting guidance.
Topics Covered
PLC and RTU roles, local autonomy, remote sites, control centers, servers, and historians
Telemetry requirements, distance, bandwidth, latency, power, environment, and availability
Signals, tags, events, alarms, timestamps, quality, buffering, and store-and-forward
Field-site architecture, addressing, asset models, documentation, and capacity planning
Remote-control authority, fail-safe behavior, degraded modes, and operational requirements
Practical Activity
Create or review a practical configuration for plc and rtu roles, local autonomy, remote sites, control centers, servers, and historians.
Build and test an exercise involving telemetry requirements, distance, bandwidth, latency, power, environment, and availability and signals, tags, events, alarms, timestamps, quality, buffering, and store-and-forward.
Use diagnostics or evidence to validate remote-control authority, fail-safe behavior, degraded modes, and operational requirements.
Key Takeaways
Explain plc and rtu roles, local autonomy, remote sites, control centers, servers, and historians.
Apply telemetry requirements, distance, bandwidth, latency, power, environment, and availability and signals, tags, events, alarms, timestamps, quality, buffering, and store-and-forward.
Validate and troubleshoot remote-control authority, fail-safe behavior, degraded modes, and operational requirements.
