Remote printing: supports other PCs within the network to print reports through Excel

Remote operation and monitoring: Implement remote operation and maintenance through the intranet, using the same operation window as the local HIS

Deployment requirements: The control network needs to be equipped with standard HIS to ensure reliability and real-time performance

CENTUM Desktop: A dedicated operating environment that hides Windows redundant features such as desktop icons and unrelated start menu items

HIS Utility tool: Configure the HIS operating environment, support user management, keyboard operations, security policies, CAMS parameters, and other settings

System management and security control

1. System management window

Window Name Core Usage Key Features

The system status overview displays the status of all sites and communication devices within the domain in a visual representation of normal/abnormal status through icons, and supports calling maintenance windows

The system alarm view displays hardware/communication error alarms arranged in reverse chronological order, accompanied by beeps and flashing prompts when triggered

The FCS status display view displays the hardware configuration and operational status of FCS, supports starting/closing control stations, and color coded device status

The HIS status display view shows the hardware configuration and operational status of HIS, and supports the effectiveness of switching control buses (Vnet/IP)

The HIS settings window includes 18 configuration tags (monitor, printer, trend, multi monitor, etc.) for configuring HIS operating parameters

2. Safety control system

Adopting a dual layer architecture of "CENTUM dedicated security+Windows IT security":

CENTUM dedicated security:

Permission classification: Level 3 standard permissions (S1 for monitoring only, S2 for monitoring+operation, S3 for full permissions)+Level 7 custom permissions (U1-U7)

Control granularity: Support setting operation permissions by function block and window, important operations require secondary confirmation

Tag priority: can mark important tags, ordinary tags, auxiliary tags, and differentiate alarm processing

IT security features:

Security Model: Supports traditional models, standard models (defense against network/direct attacks), and enhanced models (full threat defense)

Advanced features: password expiration (14 day advance reminder), prohibition of duplicate passwords, automatic logout (no operation timeout), user lockout (multiple password errors)

Authentication mode: Supports Windows single sign on, integrates Windows user accounts and HIS operation permissions

CAMS for HIS Alarm Management Core Function

As a core alarm management tool, following the EEMUA 191 standard, it solves the problem of alarm overflow:

1. Alarm integration and filtering

Integration scope: CENTUM VP process alarms, system alarms, operator guide messages, and external system alarms such as ProSafe RS and STARDOM

Filtering function: Basic filtering (process/system alarms), user-defined filtering, temporary filtering, supporting sorting by priority/response time

2. Intelligent alarm processing

Suspend function: Move non essential alarms to a temporary area and support manual/automatic shelving (triggered by conditions)

Suppression function: Suppress message display according to preset alarm groups/sites, reducing operation and maintenance load

Alarm setting value management: Save the engineering stage setting value as the benchmark value, support comparing the benchmark value with the current value, and overwrite updates

3. Data archiving and traceability

Support long-term data archiving, with the ability to trace alarm records through a historical viewer

Alarm details: including value-added information such as root cause analysis, role-playing suggestions, historical operation processes, etc

Applicable scenarios and industries

Applicable industries: factories in various fields such as petroleum refining, chemical industry, steel, food, electricity, etc

Core value: By visualizing operations, intelligent alarm management, and remote operation and maintenance, we aim to improve the efficiency and safety of factory operations, and support rapid decision-making

Key issues

Question 1: How does HIS's multi display support and data update feature meet the high-frequency operation requirements of industrial scenarios?

answer:

Multi monitor support: One HIS can connect up to four monitors and support single button switching of display content. It can simultaneously display various types of windows such as graphic views, trend views, alarm monitoring, etc., avoiding frequent window switching and adapting to the parallel monitoring needs of multiple parameters in industrial scenarios;

Data update performance: The data collection and display update speed is as fast as 1 second, meeting the real-time requirements of manual control of key parameters such as pressure and flow, and ensuring synchronization between operation instructions and feedback;

Hardware adaptation: The dedicated operation keyboard adopts a flat key design and one key operation logic. The 8-key control type includes a touch sensor, which reduces the fatigue of high-frequency operations and improves operation accuracy.

Question 2: As a core alarm management tool, how does CAMS for HIS solve the problem of alarm flooding in industrial scenarios?

answer:

Multi level filtering: supports basic filtering (by alarm type), user-defined filtering (by priority/response time), and temporary filtering, accurately filtering key alarms;

Intelligent processing mechanism: Reduce the number of alarms by "shelving" (temporarily hiding non essential alarms), "suppressing" (blocking redundant alarms by group/site), and "overlapping merging" (integrating duplicate alarms on the same label);

Value added information support: Alarm with root cause analysis and role-playing suggestions, helping operators quickly locate problems and avoid ineffective operations;

Set value management: Compare the benchmark alarm set value with the current value, promptly correct unreasonable settings, and reduce false alarms from the source.

Question 3: How does HIS's dual layer security control system ensure the operational safety of industrial control systems?

answer:

Fine grained control of permissions: CENTUM's dedicated security support divides the scope of operations according to user groups (such as specific FCS/windows), restricts operation permissions (monitoring/operation/engineering) according to permission levels (S1-S3+U1-U7), and requires secondary confirmation for important function block operations;

IT Security Enhancement: Implementing user account control based on Windows security features, supporting password expiration, prohibiting duplicate passwords, automatic logout, and defending against illegal login and password leakage;

Security model adaptation: Three security models (traditional/standard/enhanced) are provided, which can be selected according to the risk level of the factory. The standard model defends against network and direct attacks, while the enhanced model covers component theft and data leakage protection;

Operation traceability: User operation records are bound and archived with usernames, supporting security event traceability for easy responsibility identification and risk investigation.
