profibus or profinet communication to other machine

userxyz · Aug 23, 2008

Hi,

I need communication to a machine of an other company...

We just need to communicate some bits and 1 real value.

My question is what to use...

DP-DP coupler = this works for I/O and reals and so on... ?

Or should I use a CP342 or CP343 ... ?

Does a PN/PN coupler exsists ?

How far away?

You could just go wireless mux and forget the network...

Far as I understand .If both of the PLCs have Frofibus port, use profibus a same for Profinet or MPI.
You didn't mention what type of ports you have.

Give us more info we can help.

We will have a PN/DP CPU

But the other company = donno yet, I think profibus.

NO wireless systems !!

Why can't the two PLCs just write to the others memory like other PLCs can?
What about data consistency with the data coupler?
