• Status LEDs: Power (green), Port 1 Link/Activity, Port 2 Link/Activity, Error (red)

Working Principle:
The CP333D-S1 receives process data from the CENTUM VP controller via the Vnet/IP backbone through the system backplane. An embedded Ethernet processor (ARM or equivalent) handles protocol conversion: Vnet/IP packets are converted to Ethernet/IP, Modbus TCP, or OPC formats. The dual Ethernet ports provide redundant network paths; if one port fails, traffic automatically switches to the other within < 50 ms. Isolation is maintained via magnetics (transformer isolation) on each Ethernet port.

Advantages & Highlights:

• Dual Ethernet ports provide network redundancy without additional hardware
• Built-in OPC server eliminates need for third-party OPC software
• Vnet/IP to Ethernet/IP gateway enables seamless integration with non-Yokogawa systems
• Ring redundancy ensures zero-downtime network failover
• Hot-swap capable in CENTUM VP system

Applicable Industries:
Oil & Gas, Chemical, Petrochemical, Power Generation, Pharmaceutical, Water & Wastewater, Manufacturing

Installation Requirements:

• Install in CENTUM VP card cage (e.g., VB3201, VB4101)
• Assign IP addresses via System View engineering software
• Use Category 5e or higher shielded Ethernet cable
• Connect to managed Ethernet switch for VLAN configuration
• Verify network redundancy path in System View before commissioning

Usage Precautions:

• Do not connect to unmanaged switches in ring topology; use managed switches with RSTP/MRP
• Set static IP addresses for both ports; do not use DHCP in production
• Maximum cable length: 100 m per segment (use fiber media converter for longer runs)
• Update firmware only via Yokogawa approved procedure using System View
• Maintain ambient temperature below +55°C in the card cage
