YOKOGAWA CENTUM VP System HMI (HIS)

Split screen mode: Three tiled modes (pen split/simulation discrete split/trend data reference mode split)

Data export: Supports graphic copying (excluding window borders), numerical data copying (including labels, time, values, status, etc.), and can be pasted into tools such as Excel

Flexible configuration: Supports displaying data with different sampling periods on the same screen, and can adjust the magnification ratio of the timeline and data axis

4. Tune View

Core function: Display the tuning parameters and trends of a single instrument, support parameter adjustment

Display content:

Basic parameters: PV (process variable), SV (set value), MV (operating variable), operating mode, alarm status

Tuning parameters: proportional (P), integral (I), derivative (D) parameters, limit settings (HH/PH/ML/LL, etc.)

Trend curve: Real time display of PV, SV, MV trends over time, supporting axis scaling

CAMS for HIS message monitoring (core alarm management tool)

Following the EEMUA 191 alarm management standard, solving the problem of alarm overflow, the core functions include:

Multi system alarm integration: Centralized display of alarms and events for CENTUM VP, ProSafe RS, STARDOM, and PRM

Intelligent filtering function:

Filtering/Sorting: Basic filtering (process/system alarms), user-defined filtering, temporary filtering

Eclipsing: Integrating duplicate alarms of the same label into a single line display

Shelving: Manually/automatically move non essential alarms to temporary areas

Load Shedding: Automatically activates preset filters when a large number of sudden alarms occur

Suppression: Suppress redundant messages by alarm group/site

Alarm value-added information: configurable monitoring purposes (safety/environmental/economic), target user groups, response time, priority, root cause analysis, processing flow, etc

Alarm setting value management:

Save the set values of the engineering phase as the baseline values, and support comparing the baseline values with the current values

Display differences in set values, support benchmark values to override current values or vice versa

Archive difference setting values for easy traceability and adjustment of records

Long term data archiving: supports long-term storage of alarm history data, which can be traced through a history viewer

（3） Auxiliary support function

1. Report function

Core purpose: Automatically generate daily/monthly reports, support production data analysis and compliance records

Tool dependency: Based on Microsoft Excel, supporting template reuse and custom creation

Imported data types: settlement data (mean/total/maximum/minimum), trend data, historical messages, tag information, real-time process data, batch data

Printing method:

Automatic printing: timed triggering, sequence message triggering

Manual printing: triggered by function keys, graphic view buttons, Excel direct printing, VB program call

Remote printing: Other PCs within the network can print reports through Excel

2. Remote operation and monitoring server

Deployment Architecture: Remote PC (Client) → Intranet → Remote Operations Server → CENTUM VP Control Network

Core function: Remote implementation of operation monitoring and engineering configuration, using operation windows consistent with local HIS

Reliability requirement: The control network needs to be equipped with at least one standard HIS to ensure real-time performance and redundant backup

3. CENTUM Desktop

Dedicated operating environment: Hide Windows redundant features (such as desktop icons, unrelated start menu items, shutdown options)

Core value: Focus on production operations, avoid misoperation of Windows system functions, and enhance operational security

4. HIS Utility tool

Purpose: Configure HIS operating environment, support multi tab settings

Core configuration items:

User management: Add/delete users, configure automatic login (only in CENTUM authentication mode)

Operation configuration: keyboard type, mouse increase/decrease mode, trend collection pen allocation

Security Policy: Set HIS Security Rules

Special configuration: CAMS for HIS parameters, remote operation and maintenance parameters, OPC interface parameters

System management and security control

（1） System management window

Window Name Core Usage Key Features

Overview of System Status: Monitor the status of all stations and communication equipment within the monitoring domain. 1. Use icons to visually display the operational status of FCS, HIS, BCV, and other equipment

2. Support calling the system maintenance window

3. Domain definition: All sites connected by the control bus (Vnet/VNet/IP)

System alarm view displays hardware/communication error alarms. 1. The alarms are arranged in reverse chronological order (latest first)

2. When the alarm is triggered, it is accompanied by buzzing and flashing prompts

3. Automatically switch to CAMS message monitoring when CAMS takes effect

FCS status display view shows FCS hardware configuration and operational status. 1. Display site information, hardware architecture, and communication bus status

2. Color identification of normal/abnormal status of equipment

3. Support starting/closing the control station
