Profinet / EtherNet/IP Deterministic Networks
The 5466-352 module manages deterministic task scheduling across the Netcon backplane. Communication between the 68030 microprocessor and the four network communication processors is handled via dual-ported RAM, ensuring high-speed data transfer and minimal jitter in execution cycles. The CPU enforces deterministic control by maintaining strict watchdog logic; upon detection of internal hardware faults, the module triggers an IOLOCK state. This state forces all output circuits and expansion racks into a de-energized condition, ensuring the system remains in a defined fail-safe state during processor or module failure.
Frequently Asked Questions
Q: What is the behavior of the system when an IOLOCK state is triggered?
A: When an IOLOCK state is triggered due to CPU or I/O module failure, all output circuits and signals are de-energized. This signal is propagated across all expansion racks to ensure the entire control system reaches a safe state.
Q: Can the CPU-040 be reset without cycling power to the entire system?
A: In simplex configurations, the CPU switch can be toggled to the reset position. If using the CPU reset button, the application will restart automatically, typically within 2 minutes. Ensure the application is stopped via AppManager on compatible CPU systems before initiating a manual reset.
Field Installation Guidelines
- Mounting: Seat the module into the designated VME slot within the Netcon chassis. Ensure the connector pins are aligned and the module is locked to maintain backplane contact.
- Backplane Interface: The CPU communicates via VME bus; ensure the chassis backplane is clean and free of debris to prevent communication errors between the 68030 and dual-ported RAM.
- Firmware Integrity: Verify firmware compatibility with existing I/O modules before initializing the application. Improper matching between the CPU firmware and I/O firmware may trigger false IOLOCK signals.
- Shielding: Ensure the control cabinet is properly grounded to mitigate electromagnetic interference, which can disrupt the VME bus data integrity.
- Validation: During initial deployment, monitor the watchdog status via the service panel to confirm the CPU has successfully synchronized with the communication processors and is executing the application logic.
