Introduction

Back gr ound Info rmat ion

• Smar t d ig ital va lve con tro llers ( DVCs) con trol valves f or man y indu str ial app licatio ns• Va lveL in k is a softwa re pro gra m that co mm unica tes wit h DVCs and mu ltip lexe rs• T est ing Va lve Link scenarios needing ma ny DVCs is expe nsive and oft en im pos sible• T he HARTSIM softwa re will mimic one or man y DVC devices and H ART mult ip lexe rs

Inten ded Use rs , Uses an d Ope rating Environ ment• HARTSI M users wil l be e ngin eers fam ilia r w it h ValveL ink a nd rela ted equipment• HART SIM will be used for testing, o per ation simu la tion , and oth er app lic ations

need ing the use o f DVC devices and H ART mult ip lexe rs• HARTSIM wil l be used in a enginee ring deve lop ment and te st ing lab

Assu mp t io ns•          Users will b e familiar with Valv eLink software and the HART pr oto col•          Accurate D VC and HART mu lt iplexer mode ls can be constructed•          Timing issues can a nd will be avoided•          All HART c om mands ca n be imp lemented by the p roject de adlineLimit atio ns•          HART SIM will only r un on Windows base d PCs• HARTSI M’s d esign must be open-ended fo r fu ture exp ansion

Design Requirements

Desi gn Ob jec tives•          Windows ba se d so ftwar e capab le of monitor ing and g ene rat ing HART messag es•          In tuitive gra phica l user int erfa ce•          Use r co nfigu red DVC/HART mu ltiplex er devic esFuncti on al Re qu irements•          Ac cu ra tely em ula te physical D VC/H ART multip lexer devic es•          Com municat e be twee n PC ser ial ports u sing the HART pr oto col•          Maint ain a com mu nications log of all messages sen t and received•          Save dev ice con figur atio ns

End-Product DescriptionHARTSI M will be a Win dows based so ftware too l cap able of e mula ting Fisher Co ntr ols DVCs andHART mult ip lexe rs. HAR TSIM will be ca pa ble of com mun icating be tween two PCs with Fisher ’sValveL ink sof tware via th e s eria l p or t using the HART c omm unic ation pro toco l. T he s oftware w ill beused by design enginee rs at Fisher Contr ols for developme nt a nd testin g of ValveLink.
