Typical Application Fields

• Petroleum and petrochemical, natural gas, oil refining, and chemical raw material production
• Power and energy (power plants, distribution networks)
• Pharmaceutical and biotechnology
• Heavy industries such as iron and steel, cement, and papermaking
• Process Safety Instrumented Systems (SIS) and Emergency Shutdown (ESD) systems

Key Points for Installation and Maintenance

Installation

1. Fix the module using DIN rails according to the instruction manual, ensuring the rack is level.
2. Connect the 24 V DC power supply, and check the polarity and voltage range.
3. Select and insert the required communication cards into the backplane, ensuring the card slots are locked tightly.
4. Follow the IEC 61804 standard during wiring, and use explosion-proof junction boxes.

Debugging

1. Perform self-inspection using diagnostic software (e.g., HIMA Safety-Suite) to confirm the normal operation of redundant links.
2. Configure network parameters (IP, node address) and conduct fieldbus node scanning.

Daily Maintenance

1. Regularly check the power supply and heat dissipation holes for blockages, and maintain ventilation.
2. Conduct a functional self-inspection every 6 months and record logs for traceability.
3. In case of faults, use the hot-swap feature to replace faulty modules, allowing the system to complete switching without interruption.
