Technical specifications: Supply voltage, input/output types, current ratings, environmental limits (temperature, humidity), dimensions and mounting.
Pinout & wiring diagrams: Critical for safe connection of power, I/O, fieldbus, and grounding. Note terminal numbering and signal polarity.
Mounting & mechanical instructions: DIN-rail or panel mounting steps, clearance requirements, and shock/vibration limits.
Commissioning & configuration: Default addresses, DIP switches or software-configurable parameters, bus/node setup, and baud rates if networked.
Diagnostics & LEDs: LED meanings, status/error codes, and recommended responses.
Maintenance & spare parts: Recommended inspection intervals, replaceable components, and part numbers.
Troubleshooting: Symptom–cause–fix tables for common faults (no power, I/O not responding, communication errors).
Revision history / firmware notes: Compatibility requirements and firmware update cautions.
