Product Description

The SPIET800 is an Ethernet communication interface unit (CIU) developed by ABB to bridge legacy INFI-NET control networks with modern TCP/IP-based supervisory systems. It functions as a protocol gateway, enabling real-time data exchange between INFI 90 or Network 90 controllers and host computers, SCADA platforms, or engineering workstations over standard Ethernet infrastructure.

Rather than acting as a simple pass-through device, the SPIET800 actively buffers, formats, and prioritizes data from the INFI-NET bus, ensuring reliable delivery even during transient network congestion. Incoming process values, alarm states, and diagnostic information are stored locally until polled by the host application via standard socket connections, minimizing the risk of data loss during communication interruptions.

Typical Applications

Migration of legacy INFI 90 systems to modern SCADA or DCS historian platforms
Remote monitoring of power plant or industrial process data via Ethernet
Integration of ABB control networks with third-party asset management software
Engineering workstation access for configuration, trending, or diagnostics without direct INFI-NET cabling

FAQ
Q: Does the SPIET800 support Modbus or OPC?
A: Not natively. It uses ABB’s proprietary host interface protocol. However, third-party middleware or ABB’s own AC 800M connectivity tools can translate this data into OPC DA or Modbus TCP if needed.

Q: Can multiple hosts connect simultaneously?
A: Typically, the SPIET800 supports one active TCP client connection at a time. Multi-client access requires an external data concentrator or OPC server.

Q: How does it differ from the SPAC800 series?
A: The SPAC800 modules are I/O or controller units within the Symphony Plus ecosystem, whereas the SPIET800 is strictly a communication gateway for legacy INFI-NET systems—no control logic resides in the SPIET800.

What's clients say about us

Excellent Emergency Support!

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
