Re: [foxboro] I/A 7.0 Configuration

Yazid,
        You are right in saying you won't need DNBI's and DNBT's for the XP
stations but I "think" you will still need a new RCNI for each of those
stations.  Many stations can be connected through their individual RCNI's to
a hub that can be connected to a single NCNI.  This is true unless Foxobro
has decided that the letterbug can be manually defined in the workstation by
the user and doesn't need a physical letterbug which they currently use to
insure uniqueness on the bus.  If they allow that, I think all DNBI's,
DNBT's, and RCNI's could be eliminated, but only on non-redundant control
network configurations.  
        These are only my thoughts and are in no way meant to be factual.  I
would get with Foxboro to find out what their intent is.  Even though we
currently use redundant networks exclusively, I would be interested to know
the answer to your question.

Subject: [foxboro] I/A 7.0 Configuration


Hi there,

We are planning to configure I/A 7.0 system with mix of Ver 7.0 and 6.4 (XP
& NT). There will be 3 stations on I/A 7.0 and 1 station on I/A 6.4. It will
be using non-redundant Control Network configuration. Based on B0193AC
document, there was no splitter cable used at all. Is that only apply to I/A
7.0 (XP) only or it apply to all the stations (XP and NT)?
Earlier, I saw a document stating that if you have I/A 7.0 running, you'll
use NCNI and you can throw away all the DNBIs and DNBTs. Is this correct?
Based on the documents, there will always be two versions of I/A 7.0 Day0 CD
(redundant and non-redundant).

Thank you.
Yazid
