In Yokogawa DCS,
Domain means how much unit are present.
That means if in this plant 100mw x1 then domain
No is 1, if in this plant 100mw x 2 then domain is 2.
this communication done with the help of BCV and
CGW.
Station means how much FCS and HIS
Present for this unit. In yokogawa FCS start
With 01 and HIS start from 63.
so domain and station coding is always together.
It's symbol for eg. Is 0104.
here 01 is domain and 04 is station.

Answer / praven kumar m

In Yokogawa System if the no. of station is 56 or less than
56 the domain no, will be domain#1. If it exceeds more than
56 stations then we have to consider 2 domains (i.e.,
domain#1 and domain#2)

For eg. if there are 2 units, and the first unit consists
of 65 stations. in this case the first 56 stations will be
considered as domain#1 and station nos. from 57 to 65 will
be considered as domain#2. The 2nd unit will be considered
as domain#3.

Answer / prabhakaran
