As a matter of record, please be aware of some facts about Micro IA comm. w/
AB Ethernet:
1. The station image for Micro IA communicating w/ AB Ethernet has just
been released this month. Note, any prior release of this SW was either a
Beta image or other.
2. Micro IA w/AB-Eth supports both reads & writes.
3. There are specific I/O blocks that must be used to input/output data
across this link. Reference B0193YQ for a description of these blocks.
Product Testimonial:
I was personally involved w/ an application Micro IA w/AB-EthNet - the Micro
IA had over 2100 blocks installed and running - this resulted in a station
loading of approx. 45% (8mb proc card in Micro)
FYI

We tried the Micro I/A w/ AB Ethernet interface about 9 or 10 months ago.
It
handled reads fine, but writes were sketchy at best. I messed with it for a
long time thinking I was overlooking something. After some serious
heart-to-heart w/ Foxboro tech personnel, they admitted that the writes
never
worked properly for them either and they had no fixes for it.
I do not know if the problem has been fixed since then.
