To learn about Micro I/A check out the following PSSs or contact your
Account Rep. I really think that Micro I/A is a good way to go for
integrating the devices that it supports.
The two most interesting are:
PSS 21H-6A1 B3: Micro-I/A Station Overview
PSS 21H-6C6 B4: Micro-I/A Allen-Bradley PLC5/E Remote I/O Interface
The remaining ones are:
PSS 21H-6B1 B4: Micro-I/A 24 V dc Power Supply (Type 1)
PSS 21H-6B2 B4: Micro-I/A Battery Backup Unit (Type 1)
PSS 21H-6B4 B4: Micro-I/A Type 1 Station
PSS 21H-6B6 B4: Micro-I/A Single or Dual Cable Ethernet Interface
PSS 21H-6B7 B4: Micro-I/A I/A Series Fieldbus Interface
PSS 21H-6B8 B4: Micro-I/A Allen-Bradley Remote I/O Interface
PSS 21H-6B9 B4: Micro-I/A GE Fanuc Direct Connect I/O Interface
PSS 21H-6C1 B4: Micro-I/A FoxBlock Integrated Control Software
PSS 21H-6C2 B4: Micro-I/A 6.5 V dc Power Supply (Type 1)
PSS 21H-6C3 B4: Micro-I/A 486DX4-75, 4 and 8 MB Processors
PSS 21H-6C4 B4: Micro-I/A PROFIBUS-DP Remote I/O Interface
PSS 21H-6C5 B4: Micro-I/A Modbus Remote I/O Interface

No, we are not oposed to this solutin, but I for one am
totaly
unfamiliar with it. Does it integrate well into a sytesm
based up 51
serries AP/QP/AW's, with the orignal I?A I/O structure, and
AB PLC5's?

There is a desire for that, although myself I don't think it
is
imprtant based upon:
1. There is still only a single PLC (as in no PLC
edundancy).
2. The Fooxboro hardware has a long history of reliabilty in
our mill.

I would find this troubling. At presnt I can reboot (or
shutdown for
backup) any AP/WP/AW on any node and, as long as I don't
have any other
abnormal occurences, it is transparent to controling the
process.
If I had a Sun workstation that was a critical part of the
communications path to my PLC's I could not do this. This is
unfortunate, because this should be a huge preformance win
over any
other solution.
I think taht a system using to Sun's could be designed to
provied
redundant commuctioan paths to/from the PLC. IMHO tyhis
would be the
ideal solution. I will admit it would be a bit costly, but I
think I
could justify the cost for teh preformance, and reliability.
