Answer / rajkumar

starting from your control desk terminal --- i/o details in
i/o cards of ur DCS or PLC ---terminal block details of i/o
rack cabinet----any marshalling cabinets in between that
terminal details---any interface in power room ie.. like
motor control panels---- then field junction box terminal
details---- then final field devices like txr or valve or
motor terminal details. Then you can finish your loop
drawing joining control room /i/o cabinet/marshalling
cabinet/ power interface room if exists/field jn box/field
device terminal.
