While the basic safety circuit has changed dramatically over the year (what used to require a simple e-stop wired to a standard relay, now requires multiple safety strings into a safety monitoring relay), the best development has been the acceptance of the safety rated plc.&nbsp; As safety circuits have become more and more complex, designing and troubleshooting safety has become exponentially harder.&nbsp; The safety plc has made the whole process much more manageable.&nbsp; Now safety can be configured in complex combinations, while reporting the cause of a shutdown can be much more reliable.<\/p>\n\n\n\n<p>WBA has implemented dozens of plc-based safety systems, utilizing several different models of safety PLCs.&nbsp; These have included:&nbsp; Allen-Bradley Safety CompactLogix, Allen-Bradley 440 programmable safety relay, Pilz, Safety PLCs,and Phoenix Contact safety PLCs.<\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-3 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img data-recalc-dims=\"1\" decoding=\"async\" width=\"122\" height=\"125\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/download-22-e1563373021966.jpg?resize=122%2C125&#038;ssl=1\" alt=\"\" data-id=\"334\" data-full-url=\"https:\/\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/download-22-e1563373021966.jpg\" data-link=\"https:\/\/www.wba.systems\/wba\/download-22\/\" class=\"wp-image-334\"\/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img data-recalc-dims=\"1\" decoding=\"async\" width=\"167\" height=\"125\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/images-8-e1563373009366.jpg?resize=167%2C125&#038;ssl=1\" alt=\"\" data-id=\"338\" data-full-url=\"https:\/\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/images-8-e1563373009366.jpg\" data-link=\"https:\/\/www.wba.systems\/wba\/images-8\/\" class=\"wp-image-338\"\/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img data-recalc-dims=\"1\" decoding=\"async\" width=\"95\" height=\"120\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/download-25-e1563372834240.jpg?resize=95%2C120&#038;ssl=1\" alt=\"\" data-id=\"337\" data-full-url=\"https:\/\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/download-25-e1563372834240.jpg\" data-link=\"https:\/\/www.wba.systems\/wba\/download-25\/\" class=\"wp-image-337\"\/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img data-recalc-dims=\"1\" decoding=\"async\" width=\"270\" height=\"137\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/download-24-e1563372762161.jpg?resize=270%2C137&#038;ssl=1\" alt=\"\" data-id=\"336\" data-full-url=\"https:\/\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/download-24-e1563372762161.jpg\" data-link=\"https:\/\/www.wba.systems\/wba\/download-24\/\" class=\"wp-image-336\"\/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img data-recalc-dims=\"1\" decoding=\"async\" width=\"136\" height=\"120\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/download-23-e1563372709437.jpg?resize=136%2C120&#038;ssl=1\" alt=\"\" data-id=\"335\" data-full-url=\"https:\/\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/download-23-e1563372709437.jpg\" data-link=\"https:\/\/www.wba.systems\/wba\/download-23\/\" class=\"wp-image-335\"\/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img data-recalc-dims=\"1\" decoding=\"async\" width=\"209\" height=\"160\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/picture10-2-e1563372916513.jpg?resize=209%2C160&#038;ssl=1\" alt=\"\" data-id=\"339\" data-full-url=\"https:\/\/www.wba.systems\/wba\/wp-content\/uploads\/2019\/07\/picture10-2-e1563372916513.jpg\" data-link=\"https:\/\/www.wba.systems\/wba\/picture10-3\/\" class=\"wp-image-339\"\/><\/figure><\/li><\/ul><\/figure>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>It is hard to avoid safety in today\u2019s world. &nbsp;It is always best to design safety into the system, rather than add it in later.&nbsp;
