Interconnection is possible with a unified standard without the need to create a proprietary program. Enables concentration on what one wishes to do.<\/p>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t

OPC (OPC Classic) is a process communication standard developed by Honeywell, Siemens, and Microsoft in 1996 to transmit and receive data between different manufacturers and devices. It is based on Microsoft's COM\/DCOM technology and is designed to work in a Windows system. The specification was originally conceived for interoperability in processor control in plants and factories.<\/p>\r\n\t\t<\/div>\r\n\t\t

    Because of two critical incident occurrences and the IoT shift. <\/h4>\r\n\t\t\tIn 2010, a cyber attack by \"Stuxnet\" occurred on Iran's nuclear facilities.<\/b>\r\n\t\t\t

    Overview: Targeting PLCs manufactured by Siemens AG
    \r\nDamage: 8,400 centrifuges were hijacked, rendering them all inoperable<\/p>\r\n\t\t\tIn 2016, a \"Crash Override\" cyberattack occired on a Ukrainian power facility.<\/b>\r\n\t\t\t

    Overview: Malware caused a major power outage.
    \r\nDamage: Tens of thousands of residents experienced a blackout lasting about an hour and 15 minutes in the northern part of Kiev, the capital of Ukraine.<\/p>\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/section>","protected":false},"excerpt":{"rendered":"What is OPC UA Introducing OPC Classic Before the OPC Classic Communicating and sharing data between devices w ...","protected":false},"author":2,"featured_media":173,"parent":600,"menu_order":200,"comment_status":"closed","ping_status":"closed","template":"page-nosidebar-fullthumb-h1.php","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_locale":"en_US","_original_post":"51","footnotes":""},"class_list":["post-604","page","type-page","status-publish","has-post-thumbnail","hentry","en-US"],"acf":[],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t
