Safer, smarter op­er­a­tions

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

The Allen-Bradley Guard­mas­ter GuardLink safety sys­tem is a new safety- based com­mu­ni­ca­tions pro­to­col that helps op­er­a­tors re­duce and im­prove ma­chine di­ag­nos­tics and down­time while in­creas­ing pro­duc­tiv­ity.

Tra­di­tion­ally, safety de­vices are wired to sep­a­rate safety in­puts, which re­quires sig­nif­i­cantly more wiring and in­tro­duces more po­ten­tial fault points, says dis­trib­u­tor Rock­well Au­to­ma­tion. When wired in this se­ries con­nec­tion, cus­tomers lose the abil­ity to dis­tin­guish in­for­ma­tion from each de­vice. With GuardLink, safety de­vices are eas­ily con­nected in se­ries while pro­vid­ing ac­cess to in­di­vid­ual de­vice di­ag­nos­tics. This sys­tem pro­vides safety, di­ag­nos­tics, re­mote re­set and lock com­mand over a sin­gle four con­duc­tor ca­ble with up to 32 de­vices per link. In ad­di­tion, cus­tomers can greatly re­duce in­stal­la­tion cost, with up to 38 per­cent re­duc­tion in wiring, when us­ing GuardLink, prom­ises RA.

The GuardLink tech­nol­ogy seam­lessly in­te­grates with Allen- Bradley Guard­mas­ter safety re­lays and com­po­nents, al­low­ing users to ac­cess sta­tus in­for­ma­tion through­out their en­tire safety sys­tem. The con­nec­tion of safety de­vices with smart taps en­abled by GuardLink tech­nol­ogy and stan­dard ca­bling to a Guard­mas­ter safety re­lay al­lows greater vis­i­bil­ity into the sys­tem, down to in­di­vid­ual guard doors and E- stops.

“When an e- stop or in­ter­lock switch is op­er­ated, the in­di­vid­ual safety sig­nal is sent to the Guard­mas­ter safety re­lays,” said Paul Costantin, busi­ness man­ager, com­po­nents, Rock­well Au­to­ma­tion – South Pa­cific. “That in­for­ma­tion is then com­mu­ni­cated seam­lessly across The Con­nected En­ter­prise via the Guard­mas­ter net­work in­ter­face, mak­ing it eas­ier and faster to di­ag­nose and re­pair prob­lems when com­pared to tra­di­tional wired sys­tems.”

The GuardLink safety sys­tem fully in­te­grates with the Logix plat­form with pre­de­ter­mined tag names in the Rock­well Soft­ware Stu­dio 5000 ap­pli­ca­tion. Its sim­pli­fied de­sign and re­duc­tion in wires al­lows for sim­ple plug- and­play in­stal­la­tion.
