Critical event notification tool (EPAlert). Flexible data adquisition options. Overview  Numerous  Capabilities:      System and component performance monitoring Comparison of actual to predicted performance Storage of actual to predicted performance Storage of historical data(plant field readings and calculated values) Configuration capabilities Filtered historical data for trending EtaPRO/PI Information Flow (1) DCS (2) PI Data Interface (3) PI Snapshot Table (PI Points) Source Tag Value Tag Quality Tag (5) Source Tag Value Tag Quality Tag EtaPRO Server (EtaPRO Data Points) (6) MSDE (4) PI Data Archive (7) EPTransfer Component (9) OPC Server (OPC Items) (8) EtaPRO Clients EtaPRO/PI/ECHO Information Flow (1) DCS (2) PI Data Interface (3) PI Snapshot Table (PI Points) Source Tag Value Tag Quality Tag (5) Source Tag EtaPRO Server (EtaPRO Data Points) (6) MSDE (4) PI Data Archive (7) EPTransfer Component (9) OPC Server (OPC Items) (9) Redirector (8) EtaPRO Clients (10) ECHO Historian (ECHO Points) Value Tag Quality Tag Used when you don;t have PI Network Setup  Normally EtaPRO is installed in the LAN/WAN environment to allow sharing of performance information at all plant levels. EtaPRO Hardware  Hardware  Server • Windows 2003 Server or better  Workstations • Windows XP EtaPRO Software  Server  Software This application is used to: • • • • Acquire field data Perform calculations Archive historical data Provide real time and historical information to the workstation applications.  It accesses data from the source, performs calculations and maintains and updates the instantaneous data files, as well as the PI Data Archive. Components Installed in the server:         MSDE/SQL Server Express – to store client/server configuration databases EtaPRO OPC (OLE for Process Control) – to allow OPC applications to communicate with EtaPRO server. Peformance Calculation Library – to calculate the performance of most major plant equipment ECHO – to store calculated results with GP/OEM EtaPRO Systems. GP Ops Center – Central repository for important information Data Packager – to detach and reattach the Etapro configuration databases from MSDE/SQL server for troubleshooting or configuration maintenance purposes Upgrader – to validate EtaPRO 8 results against EtaPRO 9 Upgrade EtaPRO 8X Configuration – to easily upgrade an existing EtaPRO 8 configuration to EtaPRO 9, including etaPRO 8 screens. Client Software  Used to    view real-time and historical information. Configure and maintain the EtaPRO configuration on the server Access the other EtaPRO tools Data point displays Integrated engineering units conversion System configuration tool System builder tool Historical trend recovery tool Diagnostics maker Electronic Operations Log EPAlert GPSteam library& properties calculator  Components           The client updates with new data the EtaPRO server at a user defined rate, typically once each minute. Methods of acquiring data from external devices  Direct PI Connection  EtaPRO points are directly connected to a PI Data Archive to retrieve required process data.  All PI tags settings are stored in the System Configuration Database  Our OSIsoft PI system is installed on the EtaPRO server(Supplied by GP).  OPC (OLE for Process Control)  This allows EtaPRO to connect to any OPC data source on a point by point basis.  The System Administrator simply browses to the desired OPC source and seats the OPC tags into EtaPRO. System Operational Requirements  The     following must be true for the workstations to access and use EtaPRO: EtaPRO server running Windows 2003 OS PI system running EtaPRO server software running Workstations must be on-line, connected to the EtaPRO server and running the EtaPRO client software Starting the EtaPRO Client Software  Power up the workstation  Click the EtaPRO 9.0 Client icon located in Start | Programs Files | EtaPRO  Due to OSF EtaPRO security is configured using EtaPRO security it will display the log in window, enter username and password  Because autostart is configured it will auto connect to the selected server. Security Settings   It is managed through the configuration tool in the client software Two modes of security available   EtaPRO Windows • Based on windows user names and group names  Four security roles can be set for each unit configuration. The order of precedence used by EtaPRO is:      Deny – Deny access to EtaPRO Administrator – can make all type of change User – add user screens and trends View – read only In addition a top level of Administrator can be defined to have full control of EtaPRO. System Alarms   Alarm checks are performed on all values displayed in EtaPRO Two alarm categories  Quality Alarms • Indicate a problem with the reliability or accuracy of a data point value • Have precedence over operational alarms (Data point with quality problem operational is not performed). This type of alarm cascades to other data points that depend on the data point in alarm.  Operational Alarms • Indicates how a data point value compares with normal and safe plant operating limits  When a data point is in alarm the background color for the data point will change color.  See Help | Alarms Legend Alarm Types  Bad Field Status  If the PO system indicates a bad input(bad, iotimeout,etc), a default is substituted for an acquired data point experiencing a data input failure A point not available from its data source, a default will replace it    Data Acquisition Failure  Out-of-Integrity Range  Point outside of its integrity range limits EtaPRO had determined inconsistent value with physical Characteristics of the plant process Ocurrs when information for a point is configured incorrectly Invalid   Database Configuration Error  EtaPRO Data Points  Acquired points types (Pag. 2-13)   Acquired – are process variables, i.e., pressure, temp. Etc. retrieved from a DCS, OPC server or OPC client connected to EtaPRO. They also can be calculated values from a DCS or spreadsheet. Operations Log – comes from the operations data log and can be stored in PI. The original data source convention is recommended to be used(name from DCS). In some cases you will have the numerical value (Tag) and the other tag for alarm status of the tag. This names consist of a unit designator appended to the EtaPRO point ID. For example, in Unit 1 for the tag GTJIT100, it will be U1.GTJIT100. Is a point that is not directly acquired from a external source. There are four types: • User Defined Formula Points    Acquired Points ID names  OPC Tag Names    Derived(Non-Acquired) points  Uses an equation with appropiate independent variables(points) Initialized with XYZ coordinates. Up to three pairs of coordinates variablesfor a family of six curves can be used to model the relationship between the sched data point and two independent variables(points). Calculation template from the performance calculation library and other points. Digital calculation template and appropiate arguments (other digital data points). The digital calculation returns a value or status. • XY Coordinate Schedule Points  • Calculation Template Points  • Digital Label Points  Derived Points Naming Convention  The following example shows the format (pag 214): Tag: TPT.IR0.D Legend:  T = 1 Char intermediate/screen  P = 1 Char Process identifier  T = 1 Char System/Component  IR0 = 3 Char identifier  D = 1 Char Suffix   Using the tables on page 2-14, 15, 16 this point is interpreted as a calculated data point for “a design turbine extraction pressure off the intermediate pressure section that is displayed on the turbine screen”.  Intermediate Points Characteristics: • • • • Has one or more acquired points (A-type) as an argument Configured uniquely for a given system Uses calculation template 002(value = default value) Configured for the electronic operations log or virtual plant. Mapping Tool  Shows the hierarchical structure (similar to a directory) used to configure any data point in EtaPRO. Also, identify where the data point is used(reverse mapping) in the calculation of derived data. EtaPRO Trending  Basic  Trending  The trend recovery feature allows up to 15 data points to be trended versus time.(time scale can be changed) Click Trend recovery button or View | Trend Recovery
