ולידציה - URS Contents This article was written by Iian Shaya, validation,automation and control expert A URS usually presents the user's requirements for installing and operating a system designed to monitor and control specified conditions at its facility : The user's requirements may be divided into 4 categories Installation Requirements Operation Requirements Regulation Requirements HMI Requirements Installation Requirements These requirements are intended to cover all the issues regarding system installation to ensure its proper functionality and reliability. Examples of this type of requirements are: List of required hardware ( HW ) components, such as system PC, Programmable Logic Controller * ( PLC ), and varied environmental conditions sensors and control devices Labeling and identification requirements for each HW component Requirements for the software ( SW ) programs installed on the system PC Storage capacity Required connections to various types of sensors, communication units, temperature, humidity and pressure transmitters, illumination devices, etc Communication compatibility with equipment already installed at the user's facility without extra sensors Operation Requirements These requirements cover all the operations that the system must be capable of performing. Examples of this type of requirements are Environmental conditions (such as pressure, temperature and humidity) to be monitored and controlled Type of systems to be monitored and controlled, such as Heating, Ventilation and Air Conditioning ( HVAC ) system, types of sensors, etc Computerized system capabilities and starting conditions System capabilities to recover from failures Internal tests to be performed regularly, and alarm indications to be issued in case of failure Provision of current and historical alarms regarding all parameters in any case of deviation from the limits specified in the system System real-time screens display capabilities Provision of the following data and HMI displays Synoptic screens for displaying online values and status Data logging and storage of historical trends, events and alarms Tabular screens for displaying events and alarms Graphical screens for displaying trends Display of the following information for each alarm Status - new/acknowledged alarm Time at which the alarm was activated Parameter/Tag/Name of the module that activated the alarm Alarm Description Alarm Priority Display of alarms to warn the user, collect alarm history, and enable the user to view current and historical alarms. The system alarms shall include Component malfunction/failure Irregularity in parameter reading - such as disconnection of communication lines Parameters values exceeding the high/low parameter limits Deviations of system operation from predefined parameters/operations Capability of configuring the graphs parameters according to Date and time Measured parameters Predefined number of displayed parameters Trend graphs with maximum and minimum allowed limits of the monitored parameters Logging interval defined by the user and configured by the supplier Capability of authorized user's personnel to define low and high limits and delay time for each alarm parameter .On URS regulatory & HMI Requirements you can find out in our this link: URS - Regulatory & HMI Requirements * Here are some examples of the PLCs used by smartlogic: 6XV1830-0EH10, 6ES7131-4BF00-0AA0,6ES7193-4CA40-0AA0,6ES7134-4GD00-0AB0,6ES7193-4CA40-0AA0, 6ES7138-4CA01-0AA0,6ES7193-4CC20-0AA0, 6ES7590-1AB60-0AA0, 6ES7511-1AK00-0AB0, 6ES7954-8LP01-0AA0,6ES7155-6AU00-0BN0 This article was written by Iian Shaya, validation,automation and control expert
