Hi Dave,
No experience with Matrikon, but if you're using it for data collection it
might also be interesting to check out OSI PI. We've been using it for
about 10 years, collecting +/- 7000 tags through foxapi from an AW51 E
which is also being used as BatchSuite server and operator station.
Scanning rate depends on the tag setting, some are being scanned on event
trigger others on fixed scan rates. Very reliable, lots of possibilities
using the data in VB apps. We mostly collect data, but we do have some
tags writing to the AW51 also.
Mesh 8.4.2, unix 6.3
Kind regards
Dirk

Hello List,
Does any one have any experience with the Matrikon OPC Server for Foxboro
I/A?
I am interested in the following:
* Whether or not you are using the FoxAPI or OM API version?
* Are you on Solaris or Windows? Which model AW?
* Are you on nodebus or MESH?
* What is your I/A version?
* How many points collected, update frequency, and for what purpose?
* Has the server been reliable?
o How long has it gone without issue?
o How often do problems arise?
o What has been the symptoms and sources of trouble?
* Are you using primary, distributed load, or stand-by server option?
* Are you using COM (client local to server), DCOM, tunneling, or other?
* Are you specifying a delta value and a scan rate for each point?
o If so, does this mean the OM scanner in the remote station will
scan .......the OM list for changes greater than delta every x seconds,
and .......report a change to the station requesting the object?
o Is delta specified in engineering units?
o Is scan rate in seconds?
o If no attribute is specified what are the defaults?
* Is there a way to make the FoxAPI or OM API AW redundant? In other
words, should something happen to the collector AW can a backup AW be
automatically brought on-line to collect the points for the OPC Server?
Thanks,
Dave
