Re: [foxboro] The best of the Jungle!

The way hardware and software goes through such rapid development, one =
can only try and keep up wherever possible.  We now have 23 nodes on =
our system and have decided to move all of the software to version 6.3 =
for all of our AW/AP's and WP's and the v2k_01 software version for all =
of our controllers.  So far, this release shows good stability and =
should serve us for at least the next five years.  Moving to this =
release will eliminate your having to keep up with what software is on =
what controller and which quick fixes need to be applied.

Cost is a major factor in standardizing the rest of the hardware as far =
as workstations and other Sun products.  We have a pretty good mixture =
of workstation hardware with 51B and 51D and 51E boxes.  The =
'advantage' program allows an opportunity to get everything at the same =
level but this advantage disappears each time Invensys/Foxboro follows =
Sun into another box.  All one can do is weigh the cost of training, =
spare parts, and maintenance on older hardware against the cost to =
upgrade.  When these costs equal or surpass the 'latest and greatest', =
look to the horizon to see if something new is coming out before you =
jump onto the 'advantage' bandwagon.  For example, right now might not =
be a good time to start upgrading since Solaris 8 is on the verge of =
being our new operating system for unix and that includes a NEW =
workstation processor type.

Subject: [foxboro] The best of the Jungle!


Hi List,
We have several DCS Foxboro  to make control in our petroleoum =
refinery.
Since Y2K remediation, the new projects suggest to install the last =
vesion
and now a day we have a jungle of version in software and hardware and
several quick fixes required for each version too.
My question is:=20
Based on your experiences what do you recommend to make a good
administration and support about the upgrades for this kind of systems =
in a
big distributed application as in our case?
Could you please suggest a good selection to standarize the system and
reduce the knowledge, spare parts, etc required  for at lease 5 years?

For example we have (as a main description of our systems) the =
following
list:
Foxboro I/A vesions 4.3, 6.1, 6.1.2, 6.2.1
CP 10, 30, 40B, 60
AW, AP, WP Series 50, 51, 70 styles A, B, B1, D, E

Thank you very much for your concepts.

Sincerly,
Eudilson Nunez
