Detailed Module Descriptions
1. SPNPM22 – Network Processing Module
The SPNPM22 is a high-performance network processing module (NPM) designed specifically for ABB Symphony Plus Harmony Rack (HR) series controllers and Bailey INFI 90 DCS. Powered by a 32-bit ColdFire MCF5407 processor at 160 MHz with 8MB DRAM and 512KB NVRAM, it serves as a high-speed gateway between ControlWay and Cnet, carrying the Harmony Control Unit (HCU) database. The module supports communication protocols including ControlWay (1.0 Mbaud), Ethernet, and Modbus TCP/IP, with a continuous communication rate of 2,000 XR/s and burst rates exceeding 6,000 XR/s. It manages communication with the SPNIS21 module via a dedicated I/O expander bus.
2. SPNIS21 – Network Interface Module
The SPNIS21 is the front-end of every Cnet communication interface in the Symphony system, serving as the intelligent link between a node and the Cnet. It allows any node to communicate with any other node within the Symphony system. The module supports up to 62,000 nodes on Cnet (INFI-NET) and offers communication rates of 10 Mbaud, 2 Mbaud, or 0.5 Mbaud. Power requirements: +5VDC at 825mA (4.1W) or +5VDC at 1.1A (5.5W). The SPNIS21 works in conjunction with the SPNPM22 to provide Harmony control unit access to the Control Network.
3. SPIIT13 – INFI-NET Transfer Module
The SPIIT13 is an INFI-NET to INFI-NET Local Transfer Module in the ABB Symphony Plus (Harmony Rack) series, acting as a "bridge" within the DCS system. It facilitates seamless data transfer between diverse industrial networks, supporting data transfer rates up to 10 Mbps via an Ethernet/IP interface. The module features an RJ45 connector, operates on 24VDC power, and functions within a temperature range of -20°C to +70°C.
4. SPIIL02-L – INFI-NET Local Interface
The SPIIL02-L is a specialized communication module designed for ABB DCS, providing stable local INFI-NET communication between control units. Unlike remote network interfaces, the SPIIL02-L focuses on short-distance, high-speed data transmission between controllers and processors, minimizing latency and ensuring consistent system performance. It acts as a bridge between INFI-NET networks, allowing control data, status information, and coordination signals to be exchanged seamlessly. The module integrates seamlessly with ABB control modules and communication interfaces, supporting modular system expansion.
5. SPIET800 – Ethernet CIU Transfer Module
The SPIET800 (also referred to as IET800) is the core Ethernet CIU transfer module for Symphony Plus/INFI 90 systems, enabling high-speed, bidirectional data bridging between INFI-NET control networks and modern Ethernet infrastructures. Powered by a 32-bit ColdFire MCF5475 processor at 266 MHz, the module features 2×10/100 Mbps RJ45 Ethernet ports supporting TCP/IP, UDP, and Modbus TCP. It operates on backplane 24VDC (±10%) with power consumption of approximately 5–8W, and supports industrial wide-temperature operation from -40°C to +70°C. The module features 3750 VDC opto-isolation between channel and system sides and holds CE, UL, IEC 61508 SIL 2, and IEC 61850 certifications. Important: Requires separate license keys (SSBIET800000 for base / SSBIET800A0000 for advanced).
6. SPICT13A – INFI-NET Computer Transfer Module
The SPICT13A is a high-performance INFI-NET to Computer Transfer Module (ICI) engineered for seamless integration within Harmony rack hardware systems. This industrial-grade interface module enables robust data communication between INFI-NET networks and computer systems, ensuring reliable process control and monitoring. The module supports standard INFI-NET protocols and is backward compatible with existing INFI-NET infrastructure while supporting modern computer interfaces. It is widely used for process control system integration, real-time data acquisition, and SCADA system connectivity.
7. SPICI03-SCIL – INFI-NET Computer Interface
The SPICI03-SCIL is a critical communication interface module designed for the Bailey Infi 90 DCS, belonging to the renowned INFI-NET family. Specifically engineered as a Cnet-to-Computer Interface, it serves as the vital bridge between the INFI-NET communication highway and higher-level computer systems or workstations. The interface supports bidirectional communication, allowing data to flow reliably from the INFI-NET system to the computer and vice versa. It supports SCIL protocol for communication with remote terminals, printers, and other systems, and can be configured for point-to-point or multi-point communication on the same SCIL cable.
