Core features and hardware composition of HIS
(1) Core design philosophy and characteristics
Ergonomic Design: Adopting the "Simple&Intuitive" concept, unifying icon styles, information layouts, and color schemes, reducing the physical and mental burden on operators, and improving operational comfort and accuracy
Multi monitor support: 1 HIS can connect up to 4 monitors, supports single button switching of monitor display content, can display multiple types of monitoring windows simultaneously, and is suitable for parallel operation in complex scenarios
High speed data update: The data collection and interface update speed is as fast as 1 second, meeting the real-time requirements for manual control of key parameters such as pressure and flow rate
Operational inheritance: compatible with traditional HMI operation logic, supporting touch operation, 8-key control, 64 function keys, reducing operator learning costs
Cross system integration capability: capable of integrating alarm and event data from CENTUM VP, ProSafe RS (Safety Instrumented System), STARDOM (Network Control System), and PRM (Field Device Management Package)
Remote operation and maintenance support: Remote operation and monitoring can be achieved through the intranet, and the remote PC can use the same operation window as the local HIS (except for some functions)
(2) Detailed explanation of hardware composition

Monitor: Supports multiple linkage (up to 4), compatible with widescreen models, supports high-resolution display, ensuring clear presentation of graphics and data
Core functions of operation and monitoring
(1) Overall display layout
The HIS display interface adopts a fixed three part structure to ensure unified operation logic and no window obstruction:
System message bar: permanently displayed at the top, cannot be hidden, core functions include:
Visual alarm prompt: Display the alarm status through button color changes and flashing
Basic information display: date and time, current username, system status icon, advanced alarm filter name
Alarm message preview: scroll display key alarm information (such as equipment failure, parameter exceeding)
Browser Bar: Foldable area on the left, with core functions including:
Window Call: Tree based Display of Operation Monitoring Window List and Factory Hierarchical Structure
Quick Tools: Preset Menu Toolbox, Tool Button Toolbox, Window History
Flexible configuration: supports minimizing hiding and does not occupy monitoring space
HIS desktop area: the core workspace, using a three-level structure of "container window frame view":
View: Single monitoring unit (such as graphical view, trend view)
Framework: Supports multiple views (up to 4 per frame), supports tab switching
Container window: the outermost "canvas" that supports multiple frames and allows for free layout
(2) Core operation monitoring window

(2) Security control system
Adopting a dual layer architecture of "CENTUM dedicated security+Windows IT security" to ensure operational and data security:
1. CENTUM dedicated security
User three attributes:
Username: Unique identifier for the operator, associated with operation logs and password
User group: Define the scope of operation monitoring (such as specific FCS, windows, factory areas)
User permissions: subdivided operation levels, default 3 levels of standard permissions+7 levels of custom permissions
Permission level monitoring permission operation permission engineering permission
S1 (ordinary operator) present or absent
Is S2 (Senior Operator) available
S3 (Engineer) Yes Yes Yes Yes
U1-U7 (custom) configurable configurable configurable
Fine grained control granularity:
Function block level: Modification of important function block parameters requires secondary confirmation, and operation permissions can be temporarily disabled
Window level: Restrict operations such as modifying graphical view dashboards and adjusting trend view parameters
Tag level: Tag priority (important/normal/auxiliary 1/auxiliary 2), differentiated alarm processing
Advanced security features:
User lockout: Multiple password errors trigger system alarm, which can lock illegal login accounts
Password expiration: password expiration period can be set, with a 14 day reminder before expiration
Prohibition of duplicate passwords: Historical passwords cannot be used when changing passwords
Automatic logout: Automatically log out after no operation timeout
2. Windows IT Security
Security Model: Provides 3 models to adapt to different scenarios
Model Type Core Defense Scope Applicable Scenarios
Traditional models lack reinforcement and prioritize compatibility with legacy products for upgrading old systems, requiring compatibility with old devices
Standard model defense against network attacks and direct operational attacks in conventional industrial scenarios, balancing security and compatibility
Strengthen model defense against network attacks, direct operation attacks, and high security scenarios such as component/data theft (such as petroleum and chemical industries)
Authentication mode:
Windows authentication mode: integrates Windows account and HIS operation permissions, supports domain management and single sign on
Single sign on method: Windows login automatically synchronizes HIS login; Or the system can automatically log in to Windows and HIS can be started with the lowest privilege
Communication control: Restrict communication types and ports through Windows firewall and DCOM settings to defend against network attacks
