SKRITCHHHH - that's the sound of the FDSI dev team taking you off their
Christmas list!
Completely agree. The AB FDSI drivers (4 of them now?) are terrible at
actually giving us the functionality that we had in the AB30s. Foxboro does
a pretty good job migrating from other systems, but migrating from their own
AB30s is apparently too challenging or not taken seriously enough.
* Documentation is incomplete, and not easily available on some drivers.
Document numbers change, and appear to be maintained differently between the
device group and the rest of Foxboro (DI documents versus B0700 documents)
* AB30 migration manual is not available on TAC site. It is distributed
with the EthernetIP driver, although apparently not with the others?
* Driver version information isn't available on the TAC site under release
notes, TAC sites don't appear to have any better access to driver
information.
* Failure to duplicate MCOUT manual functionality is a huge issue
* Failure to match the AB30 options for bit ordering results in huge numbers
of extra blocks to wrap fairly simple I/O blocks
* Type conversion not available - IIN vs PAKIN
I've got 40+ AB30s left to migrate - Foxboro could REALLY have made this job
more straightforward...
Cheers,
Kevin
I agree, the EthernetIP driver for CLX is the best of the bunch, although
it's speed/bandwidth is very disappointing.
