Hi,
are their offer customers out there which use a running I/A system and
would like to keep it running as long as possible to save the
investment?
My scenario expects that you have a running system with enough capacity
in every system level (I/O modules, CP load, powerful AWs, enough DM
licenses, ...) but you use some devices that are marked as "obsolete".
I discussed that issue with colleagues and came across that we would
like to have a standardized procedure for that case.
What kind of information do we expect TO GET FROM Invensys Foxboro?
- Every offer should contain the dates for withdrawn from sale,
transition to lifetime and no longer repairable!
- A inventory list for every plant with the following columns
Name
Letterbug
Type
Release
Description
delivery date or purchase order date
Date Introduced
Date Withdrawn from Sale
Date Transition to Lifetime
Date No longer Repairable
id (used as a pointer to another document with informations about new
Hard-/Software)
- At least one or more migration options in a table with the following
columns
(every option in one table)
id
Name
Type
Release
Description
Date Introduced
Date Withdrawn from Sale
Date Transition to Lifetime
Date No longer Repairable
Price
Prerequisites (should contain infos like more space needed | other
connector types | other file format |...)
consequential costs (based on the requirements of the new hardware or
software)
backward compatibility (yes or no)
The document with migration options should be extended by a system
drawing, some notes about the advantages and disadvantages of that
solution.
Which new features will be available using that migration option?
- A more general question: Is it cheaper to jump over one technology
generation or better go every migration step?
What are your opinions?
What would you expect?
I appreciate every comment I get.=20
