ABB Harmony Sequence of Events (SOE) system

ABB Harmony Sequence of Events (SOE) system

System Overview

Harmony Sequence of Events (SOE) is for Symphony ™ The distributed event monitoring, recording, and reporting system provided by the enterprise management and control system is mainly used to capture the state transitions of digital signals from on to off or from off to on (SOE events), collect and timestamp these events through a series of SOE modules, and provide event data support for the system.

System architecture and core components

Server Node (INSOE01 Server Node)

INNIS11 Network Interface Module: As the front-end of all Cnet (control network) communication interfaces, it is an intelligent link between nodes and Cnets.

INSEM01 event sequence main module: communicates with INNIS11 and INTKM01 modules, responsible for managing the distributed event sequence system, including processing 1500 points from up to 1000 Harmony control units (HCUs), 256 complex triggers (each containing 16 operands), and 3000 simple triggers; Configure through specific function codes (FC 243-246) to monitor Harmony control unit data based on anomaly reports, collect and organize data, and provide SOE data to the human-machine interface after triggering conditions are met.

INTKM01 time synchronization main module: provides time information to the INSEM01 module and other parts of the distributed SOE system through a time synchronization link, connects to an external receiver using an IRIG-B time code link, and transmits absolute time using an RS-485 time synchronization link; Connect the external receiver signal and time synchronization link through the NTST01 terminal unit.

I/O module

IMSET01 event sequence timing module: processes up to 16 digital field inputs, receives and decodes time synchronization link information sent by INTKM01 module; The controller interacts and configures data with the module through specific function codes (FC 241, 242), with each channel optically isolated and individually programmable to support multiple input voltages; Communicating with the Harmony controller through the I/O expansion bus, only one module can run on one I/O expansion bus segment, connecting the NTST01 and NTDI01 terminal units, responsible for the time synchronization link and on-site wiring terminals, respectively.

IMSED01 event sequence digital input module: similar to IMSET01, but only processes up to 16 digital field inputs and does not handle time synchronization link information; The controller is configured and accesses its input channels through FC 242 function codes. One I/O expansion bus segment can run up to 63 of these modules and one IMSET01 module, and on-site wiring terminals are implemented through NTDI01 terminal units.

Terminal unit

NTDI01 terminal unit: provides physical connection points for on-site wiring.

NTST01 terminal unit: used for terminal connection of time synchronization link, and also provides relevant connection support for IMSET01 module, etc.
