PVSS II

• PVSS introduction & Managers• Data Point Concept• GUI & Scripting• Alarm concept• Archiving, Trending & other features• Distributed and Redundant systems• Managing PVSS projects• Interface to External Applications

Introduction

• PVSS II is a SCADA system. • SCADA stands for Supervisory Control

And Data Acquisition.• PVSS is used to connect to hardware (or

software) devices, acquire the data they produce and use it for their supervision, i.e. to monitor their behaviour and to initialize, configure and operate them.

General features of a SCADA

• Tag /Data Point mapping of the Process parameter.

• Interface to Hardware• Alarms, Trends, HMI.• DB logging, Event logging, Archiving.• Access control, Multi-user development,

interface to external Applications, Backup.• Independent, reliable, flexible, expandable.• PVSS supports all the above features.

PVSS Managers

• A PVSS application is composed of several processes, in PVSS nomenclature: Managers.

• These Managers communicate via a PVSS-specific protocol over TCP/IP.

• Main managers are – Event Manager (EV)– Database Manager (DB).

• Managers subscribe to data and this is then only sent on change by the Event Manager, which is the heart of the system.

Managers Overview

Manager Functions

• Event manager – responsible for all

communications.– It receives data from various

managers and sends it to the Database Manager to be stored in the data base

– distributes data to all Managers

• Database manager – provides the interface to the (run-

time) data base. – Administration of system

parameterization

PVSS Managers Contd..

• User Interface Manager (UI) (Two Modes)– Editor : Parameterization and HMI design.– Visualization: Run time HMI

• API Manager – Allow users to write their own programs in C++ using a

PVSS API (Application Programming Interface) to access the data in the PVSS database & interface external applications.

• Control Manager (CTRL)– provide for any data processing as “background”

processes

PVSS Managers Contd..

• Driver Manager (DRV)– Provide the interface to the devices to be controlled.

These can be PVSS provided drivers like Profibus, OPC, etc.

• ASCII Manager (ASCII)– Allows users to export/import the configuration of a

project (DPTs/DPs – see later) to/from an ASCII file.

• Archive Manager– Allows users to archive data for later retrieval and

viewing.

PVSS API & GUIfor Indus-2 Control System

What is an API manager?• The Application Program Interface provided

by PVSS for the integration of external programs.

• Allow users to write their own programs in C++ using PVSS APIs to access the data in the database and to interact with external applications.

• It communicates with the PVSS system via a protocol defined by PVSS.

PVSS structure

• User Interface layer

• Processing Layer

• Communication & Memory layer

APIs in Indus Control system

• Used to connect PVSS SCADA to Layer-2 of control System.

• API manager communicates with L-2 on TCP/IP link.

FEATURES OF L1-L2 COMMUNICATION

1. The L1-L2 communication uses TCP/IP datagram sockets.

2. TCP/IP protocol uses its own error detection mechanisms.

3. L1-L2 communication sockets form one-to-one dedicated connections, thus avoiding problems of multicast or broadcast.

4. Every command is followed by a response that reflects the result of the service.

FEATURES OF L2-L3 COMMUNICATION

1. Galvanic Isolation has been provided on Profibus at all the stations.

2. Parity check on byte level for Profibus telegrams (packets). Every byte of the profi telegram has even parity included.

3. Frame checksum at packet level has been provided. Each profi telegram consists of a checksum byte that helps in checking the data integrity.

4. Multiple attempts: Provision for up to 3 attempts has been included at L-2 for each command that is sent to L-3 in case of no- reply /frame-error.
