In this short article we will talk about how Guardlink\u00ae works, the reason for its importance, the features and the benefits it can bring to your business.<\/p>\n<p>Two very important challenges for entrepreneurs are the\u00a0<strong>safe stopping of the machine<\/strong>\u00a0and the\u00a0<strong>reducing downtime<\/strong>. For this reason the\u00a0<strong>serial connection of safety input devices<\/strong>\u00a0has become a very popular practice.<\/p>\n<p>The real problems, however, arise in the event of intervention due to breakdowns, blocks and maintenance of the production lines. The lack of up-to-date, accurate and integrated diagnostic information in the safety control system generates an increase in the management times of machine downtime.<\/p>\n<p>With\u00a0<strong>GuardLink \u2122 technology \u2013 Rockwell Automation \u2013<\/strong>\u00a0it is possible to provide safety and diagnostic information over the same cable. This communication protocol makes it possible to simplify the system and to transmit information to the control system more quickly, allowing a common and safe management of all safety sensors. By\u00a0<strong>connecting to a safety relay<\/strong>\u00a0and using an\u00a0<strong>EtherNet\/IP network interface<\/strong>, information is easily transmitted to the control system to increase the availability of diagnostic data.<\/p>\n<p>The GuardLink\u00ae communication protocol requires no configuration and features a daisy chain cabling topology with M12, Plug and Play connectors. It also allows you to connect up to\u00a0<strong>32 safety input devices in series\u00a0<\/strong>while maintaining a high level of safety.<\/p>\n<p><strong>ROCKWELL AUTOMATION GuardLink\u00ae FEATURES<\/strong><\/p>\n<ul>\n<li>It allows access to the diagnostic data of each individual actuator<\/li>\n<li>It supports remote locking, status indication, reset and reset of errors in safety input devices<\/li>\n<li>It can be integrated with the Logix 5000 \u2122 controller platform thanks to the add-on profile in Studio 5000 Logix Designer\u00ae<\/li>\n<li>Up to 1000m connection distance (30m between one coupler and another)<\/li>\n<li>It supports the connection of safety devices with electromechanical or solid state safety outputs<\/li>\n<li>It uses the EtherNet\/IP \u2122 440R-ENETR interface to share diagnostic information over the network<\/li>\n<li>Up to two safety circuits (GuardLink\u00ae and EMSS or OSSD devices) can be supported with the Guardmaster\u00ae Dual GuardLink\u00ae (DG) safety relay<\/li>\n<\/ul>\n<p><strong>ROCKWELL AUTOMATION GuardLink\u00ae BENEFITS<\/strong><\/p>\n<p>GuardLink\u00ae allows you to\u00a0<strong>reduce wiring costs by 20% to 38%<\/strong>. This is for two main reasons:<\/p>\n<ol>\n<li><strong>Small cable size<\/strong>: 4 conductor cables for cascade connection instead of 8-pin cables;<\/li>\n<li><strong>Standard M12 connectors and 5-wire cables\u00a0<\/strong>to reduce wiring errors and save time during installation.<\/li>\n<\/ol>\n<p>This safe series connection system cascades safety signals across GuardLink\u00ae devices and enables diagnostics on the same cable. Another benefit is\u00a0<strong>remote recovery\u00a0<\/strong>to speed up machine access and reduce troubleshooting time.<\/p>\n<p>Here there are some examples of\u00a0<strong>Rockwell Automation devices<\/strong>\u00a0that can be connected to\u00a0<strong>GuardLink\u00ae device-level safety connection technology.<\/strong><\/p>\n<ul>\n<li>450L light curtains<\/li>\n<li>Dual GuardLink Safety Relay (GSR DG)<\/li>\n<li>Lifeline 5<\/li>\n<li>440G-LZ Guard Locking Interlock Switch<\/li>\n<li>800F emergency button<\/li>\n<li>SensaGuard Non-Contact Guard Interlock Switch<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/section>\n","protected":false},"excerpt":{"rendered":"GuardLink \u2122 technology is a security-based communication protocol.
