A URS usually presents the user's requirements for installing and operating a system designed to monitor and control specified conditions at its facility<\/p>\n
:<\/strong>The user's requirements may be divided into 4 categories<\/p>\n Installation Requirements<\/p>\n Operation Requirements<\/p>\n Regulation Requirements<\/a><\/p>\n HMI Requirements<\/a><\/p>\n 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:<\/p>\n List of required hardware (HW<\/a>) components, such as system PC, Programmable Logic Controller*<\/strong> (PLC<\/a>), and varied environmental conditions sensors and control devices<\/p>\n Labeling and identification requirements for each HW component<\/p>\n Requirements for the software (SW<\/a>) programs installed on the system PC<\/p>\n Storage capacity<\/p>\n Required connections to various types of sensors, communication units, temperature, humidity and pressure transmitters, illumination devices, etc<\/p>\n Communication compatibility with equipment already installed at the user's facility without extra sensors<\/p>\n These requirements cover all the operations that the system must be capable of performing. Examples of this type of requirements are<\/p>\n Environmental conditions (such as pressure, temperature and humidity) to be monitored and controlled<\/p>\n Type of systems to be monitored and controlled, such as Heating, Ventilation and Air Conditioning (HVAC<\/a>) system, types of sensors, etc<\/p>\n Computerized system capabilities and starting conditions<\/p>\n System capabilities to recover from failures<\/p>\n Internal tests to be performed regularly, and alarm indications to be issued in case of failure<\/p>\n Provision of current and historical alarms regarding all parameters in any case of deviation from the limits specified in the system<\/p>\n System real-time screens display capabilities<\/p>\n Provision of the following data and HMI<\/a> displays<\/p>\n Synoptic screens for displaying online values and status<\/p>\n Data logging and storage of historical trends, events and alarms<\/p>\n Tabular screens for displaying events and alarms<\/p>\n Graphical screens for displaying trends<\/p>\n Display of the following information for each alarm<\/p>\n Status – new\/acknowledged alarm<\/p>\n Time at which the alarm was activated<\/p>\n Parameter\/Tag\/Name of the module that activated the alarm<\/p>\n Alarm Description<\/p>\n Alarm Priority<\/p>\n 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<\/p>\n Component malfunction\/failure<\/p>\n Irregularity in parameter reading –\u00a0such as disconnection of communication lines<\/p>\n Parameters values exceeding the high\/low parameter limits<\/p>\n Deviations of system operation from predefined parameters\/operations<\/p>\n Capability of configuring the graphs parameters according to<\/p>\n Date and time<\/p>\n Measured parameters<\/p>\n Predefined number of displayed parameters<\/p>\n Trend graphs with maximum and minimum allowed limits of the monitored parameters<\/p>\n Logging interval defined by the user and configured by the supplier<\/p>\n Capability of authorized user's personnel to define low and high limits and delay time for each alarm parameter<\/p>\n \u00a0 .On URS regulatory & HMI\u00a0Requirements you can find out in our this link:\u00a0URS – Regulatory & HMI Requirements<\/a><\/p>\n *<\/strong>Here are some\u00a0examples of the PLCs<\/strong> used by smartlogic:\u00a06XV1830-0EH10,\u00a06ES7131-4BF00-0AA0,6ES7193-4CA40-0AA0,6ES7134-4GD00-0AB0,6ES7193-4CA40-0AA0,\u00a06ES7138-4CA01-0AA0,6ES7193-4CC20-0AA0,\u00a06ES7590-1AB60-0AA0,\u00a06ES7511-1AK00-0AB0,\u00a06ES7954-8LP01-0AA0,6ES7155-6AU00-0BN0<\/p>\n \u00a0This article was written by Iian Shaya, validation,automation and control expert<\/p>\nInstallation Requirements<\/h3>\n
