INTRODUCTION

The IEC 613 5 stan ard series sp cifies a Train Commu ication Network f or u age in rai way

vehicles ( rain ) mainly inten ed f or the ex han e of TCMS related information, but not

restricted to it The sp cif i ation starts f rom the ph sical layer up to the a plcation layer an it

in olves dif ferent commu ication tec nologies

This p rt of IEC 613 5 (IEC 613 5-2-3) def i es the commu ication prof ile of the Train

Commu ication Network so as to ac ieve intero era i ty b twe n Con ists con ected by

Ethernet Train Bac b nes as def i ed in IEC 613 5-2-5

The re son f or promptin the pre aration of this p rt of IEC 613 5 are:

• definition of the req irements neces ary f or commu ication intero era i ty on Ethernet

Train Bac b ne level

• f ul doc mentation of the req irements of al u ers, alg in them an set in them out

in stan ard form

• providin g idel nes for the tec nical solution ado ted for the train b c b ne

conformity of con ists to the commu ication prof ile

ELECTRONIC RA ILWA Y EQUIPMENT –

Part 2-3: TCN communication profile

This p rt of IEC 613 5 sp cif ies rules for the data ex han e b twe n con ists in train The

ag regation of these rules def i es the TCN commu ication prof ile

The o jective of the commu ication profi e is to en ure intero era i ty b twe n con ists of the

said train with resp ct to the ex han e of information F r this it def i es al those items whic

are neces ary for commu ication intero era i ty:

• an arc itecture with defined train direction related to dif ferent train views

• a common fu ctional ad res in con e t

• common commu ication protocol f or data ex han e b twe n fu ction

• a set of services f or train commu ication control

As a restriction, this commu ication profie is ad ered to the Ethernet Train Bac b ne (ETB)

tec nolog as def i ed in IEC 613 5-2-5 Toward the con ist network , a more a stract

inter ace is defined whic do s not restrict the a pl an e of an con ist network tec nolog as

f or in tan e MVB (IEC 613 5-3-1), CANOp n (IEC 613 5-3-3) or ECN (IEC 613 5-3-4)

It is not within the s o e of the commu ication profie to def i e a pl cation data content an its

me nin (e.g s ntax an semantic ) This is within the resp n ibi ty of the a plcation prof iles

Namely two a plcation prof iles are expl citly s p orted as s own in Fig re 1: the TCMS

a) If there is a le din vehicle in the train, the o erational train direction is determined by

the viewin direction of the drivin ca of the le din vehicle

If there is no le din vehicle, then the o erational train direction s al b determined by the

fol owin rules:

b) If there was a previou ly le din vehicle, then this vehicle together with its previou ly

o erational train direction determines the o erational train direction

c) If there were several previou ly le din vehicles, e.g af ter a train len thenin , an al

of these have the same viewin direction, then this viewin direction determines the

o erational train direction

d) If there are multiple con ists in the train an a traction con ist at one en , then this en
