Di­rect con­nec­tion to mo­tor cen­tre and vari­able speed drive ap­pli­ca­tions

DEMM Engineering & Manufacturing - - MOTORS & VARIABLE SPEED DRIVES -

Emer­son Process Man­age­ment, work­ing with My­nah Tech­nolo­gies, has ex­panded cus­tomers’ net­work pos­si­bil­i­ties and ap­pli­ca­tion op­tions by adding Profinet pro­to­col abil­i­ties to the DeltaV dis­trib­uted con­trol sys­tem (DCS) – fur­ther open­ing plant-floor in­te­gra­tion to DeltaV users.

The ad­di­tion of Profinet saves DeltaV users time and ef­fort by en­abling di­rect con­nec­tion be­tween the DeltaV DCS and plant floor de­vices such as mo­tor con­trol cen­ters, vari­able speed drives, and PLCs in process au­to­ma­tion busi­nesses. Tak­ing ad­van­tage of Profinet, users do not need to use a pro­to­col con­verter to con­nect to the sys­tem.

Profinet joins a wide range of DeltaV Eth­er­net- based pro­to­cols, such as Mod­bus/ TCP and Eth­er­net/ IP. The new ca­pa­bil­ity is eas­ily added to the sys­tem via both M-se­ries and S-se­ries Vir­tual I/O Mo­d­ule 2 ( VIM2) in­ter­faces.

The Profinet driver sup­ports sim­plex VIM2 mod­ules de­ployed with stan­dard com­mer­cial off-theshelf (COTS) net­work equip­ment. For en­hanced re­li­a­bil­ity and avail­abil­ity, sim­plex VIM2 mod­ules can be de­ployed with an ex­ter­nal switch that han­dles me­dia re­dun­dancy net­work topol­ogy via Me­dia Re­dun­dancy Pro­to­col (MRP) and also be­haves as the ring mas­ter.

Sav­ing time and in­creas­ing safety, the VIM2 in­ter­face and fire­wall func­tion al­low a high level of ac­cess with­out sac­ri­fic­ing con­trol sys­tem se­cu­rity and in­tegrity. The VIM2- based Profinet ar­chi­tec­ture en­ables users to op­ti­mise ex­pan­sion ac­tiv­i­ties or per­form main­te­nance op­er­a­tions on ap­pli­ca­tions in re­mote lo­ca­tions us­ing a lap­top with ven­dor-- spe­cific di­ag­nos­tic tools – all while con­stantly mon­i­tor­ing ap­pli­ca­tions from a cen­tral­ized net­work.

“Profinet is a grow­ing bus pro­to­col choice in process in­dus­tries,” said Emer­son Process Man­age­ment’s chief strate­gic of­fi­cer Peter Zornio. “The DeltaV sys­tem has a strong his­tory of in­ter­con­nec­tion to busses of all types with seam­less in­for­ma­tion in­te­gra­tion for end users. My­nah has been a great part­ner in at­tain­ing this achieve­ment, and the ad­di­tion of Profinet will help our cus­tomers re­duce their in­te­gra­tion costs.”

“We are ex­cited to work with Emer­son to bring this tech­nol­ogy to DeltaV users world­wide,” said Nobin Wil­liam, vice pres­i­dent of tech­nol­ogy at My­nah. “The VIM2 In­dus­trial Eth­er­net driver prod­uct fam­ily pro­vides cost- ef­fec­tive, high­per­for­mance in­te­gra­tion be­tween DeltaV and an incredible num­ber of plant floor de­vices. The Profinet driver ex­tends this in­te­gra­tion ca­pa­bil­ity to new mar­kets and new users.”
