Key issues

Question 1: What are the core advantages of the network architecture of the CENTUM VP system (Vnet/IP version)? What is the functional division between Vnet/IP and I/O communication bus (ESB/optical ESB/ER)?

answer

Core advantages of network architecture:

Dual redundancy design: The Vnet/IP control network adopts Bus1/Bus2 dual redundancy, which automatically switches in case of failure to ensure uninterrupted control communication;

High speed transmission: The communication speed within/between domains reaches 1Gbps, meeting real-time control requirements;

Strong scalability: Supports 16 domains/systems, 256 sites/systems, and achieves cross domain/wide area expansion through L3SW and routers.

Functional division of labor:

Vnet/IP: The system core control network is responsible for real-time control data and management information transmission between HIS, ENG, FCS and other sites;

ESB bus: I/O communication between FCS and local node units, with a speed of 128Mbps and a maximum transmission distance of 10m, compatible with the full range of AFV FCUs;

Optical ESB bus: Long distance I/O communication, based on single-mode fiber, with a maximum transmission distance of 50km, only compatible with AFV30 /AFV40 ;

ER bus: AFV10  Exclusive remote I/O communication, 10Mbps speed, maximum transmission distance of 185m, supports 4 buses/FCU.

Question 2: How does the CENTUM VP system meet FDA 21 CFR Part 11 compliance requirements? What are the key limitations to consider when expanding the system scale?

answer

FDA 21 CFR Part 11 Compliance Implementation:

Access control: Supports engineer/operator identity authentication, requires prior registration of username and password, and cannot operate without legal permission;

Permission confirmation: Independently verify whether the operator has specific operational permissions;

Audit tracking: Record engineering operations that affect product quality (such as FCS data downloads), including the operator, time, content, reason for changes, and traceability;

Data storage: Audit tracking data is stored on dedicated servers that support archiving and retrieval.

Key limitations of scale expansion:

Number of tags: default maximum of 100000 per system, maximum of 1 million after enabling LHS4000 package;

Domain and site: up to 16 domains/systems, 256 sites/systems, with a maximum of 64 Vnet/IP devices per domain;

FCS quantity: A maximum of 114 FCS per system, including up to 86 AFV30/AFV40 and up to 64 AFV10;

Control drawing: By default, a single FCS has 200 control drawings, but with the LFS1750 package enabled, the maximum is 500.

Question 3: What is the functional positioning of the core components (HIS/ENG/FCS) of the CENTUM VP system? What are the modes of multi project connection and what are the applicable scenarios?

answer

Functional positioning of core components:

HIS (Human Machine Interface Station): The operation and monitoring core provides functions such as graphical views, trend analysis, alarm management, etc. It supports desktop/console types and can integrate engineering functions;

ENG (Engineering Station): System configuration and maintenance, control logic design and equipment configuration are implemented through software packages such as LHS5100, which can be combined and deployed with HIS;

FCS (Field Control Station): controls the computing core, performs functional block operations, and I/O data exchange. The FCU supports single/dual redundancy to ensure control reliability.

Multi project connection mode and applicable scenarios:

Hierarchical Connection: The upper level CENTUM VP project monitors the lower level projects (supporting VP/CS 3000/CS 1000/CS), and only the upper level requires the installation of LHS4450 package, which is suitable for centralized monitoring of multi-level factories;

Bidirectional connection: The connected project can be monitored in both directions and is only applicable between CENTUM VPs or between VP and CS 3000. Both parties need to install LHS4450 package, which is suitable for multi factory collaborative control scenarios.
