The ABB SPIET800 is an Ethernet CIU (Computer Interface Unit) transfer module from ABB's Symphony Plus/INFI-NET series, designed to bridge legacy INFI-NET control networks with modern Ethernet/TCP/IP systems for reliable data exchange in industrial automation.

Model SPIET800 (also called IET800)

Product Type Ethernet CIU Transfer Module for INFI-NET to TCP/IP

Power Supply 24 V DC (±10%), ~20 W consumption

Communication INFI-NET to Ethernet (TCP/IP, Modbus TCP/IP); RS-232/485 ports

Dimensions 144 × 80 × 35 mm (or 139.7 × 215.9 × 88.9 mm per variant); 0.1-0.3 kg

Operating Temp -20°C to +70°C (storage -40°C to +85°C)

Protocols Modbus TCP/IP, EtherNet/IP, Profibus/Profinet compatible

Features Data buffering, high isolation, compact DIN-rail mount

Applications Industrial DCS, SCADA integration, legacy-to-Ethernet bridge

Mechanical mounting

Secure the ABB SPIET800 on DIN-rail in the control cabinet, ensuring proper ventilation and access to ports.

Power connection

Wire 24 V DC supply to the ABB SPIET800 terminals with fusing and polarity protection; verify voltage stability.

Network wiring

Connect INFI-NET cables to the ABB SPIET800 input side and Ethernet (RJ45) to the host/SCADA on the output side; use shielded CAT5/6 cable.

Configuration

Set IP address, subnet, and protocol parameters on the ABB SPIET800 via DIP switches or configuration software; license may be required separately.

Testing

Power up the ABB SPIET800, ping from host computer, and verify data flow from INFI-NET controllers with no packet loss.

Ensure stable 24 V DC (±10%) power to the ABB SPIET800 to prevent communication resets or data corruption.

Ground cable shields properly at the ABB SPIET800 to minimize EMI in noisy industrial environments.

Mount the ABB SPIET800 away from high-heat sources to stay within -20°C to +70°C operating range.

Use surge protection on Ethernet ports of the ABB SPIET800 in lightning-prone areas.

Verify INFI-NET termination before connecting to the ABB SPIET800 to avoid bus reflections.

Monthly: Monitor ABB SPIET800 LEDs for link/activity; check Ethernet cable integrity.

Quarterly: Inspect terminals on the ABB SPIET800 for corrosion; clean with dry compressed air.

Annually: Test data throughput across the ABB SPIET800 with diagnostic tools; update firmware if available.

Log communication errors from the ABB SPIET800 to predict cable or controller issues.

Replace the ABB SPIET800 if operating outside temp specs or showing persistent packet loss.
