An industrial-controller bench exposes keyed connectors, voltage rails, a differential data pair and a receiving drive. Match electrical supply and protocol settings before frames can cross the interface.
• 3D scene parts: Industrial controller and ports; keyed connector / harness; 24 v supply terminals; differential / signal conductors; receiving drive. • Controls: Supplied device voltage (12–30 V); Transmitter protocol (CAN, UART); Receiver protocol (CAN, UART); Frame transmission rate (1–10 frames/s); Disconnect harness. • Live readouts: Frames offered; Frames accepted; Frames rejected; Interface contract satisfied (0/1). • Guided experiments: Protocol mismatch; Undervoltage. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.
Valid = connected AND 20 ≤ V ≤ 28 AND protocol match Offered frames = floor(rate × elapsed) Accepted = valid ? offered : 0
Representative systems-engineering teaching example. Equipment geometry and animation time are illustrative; this is not an equipment qualification, safety assessment or certification tool. Protocol compatibility is checked at a contract level. No real bus arbitration, packet format, timing, bit errors or electrical signal integrity are solved. Try the preset experiments, then compare the live readouts with the equations.
No. The stated model omits real qualification evidence and system-specific assumptions.
Check every interface contract condition.
