HI all, I have a client with several remote CIMPLICITY HMI sites all doing their own local logging, and keeping a 3 month rolling log of data. This customer would like to automatically replicate this data back to a central server where it will be kept as a 5 year rolling log of data. In all there are probably 100 different tags that need to be logged across 5 sites, and in total producing no more than 50-100MB of data per month. We have decided that GE's Data Historian is cost prohibitive for this set up, and because CIMPLICITY use instances of the Express edition of SQL server for logging, you can't get the HMIs to publish data as part of an MS SQL replication configuration. So I am looking for ideas on how to get the logging data from A to B as cheaply as possible using 3rd party tools. And the last thing I want to do is to be forced to write a custom solution from scratch myself. So any ideas? Thanks Peter |

I don't think it would be too hard to write a simple app that you could schedule every month that would pull the new data from the remote hmi sites and then do a delete from table where time > 5years; what route did you end up going on this? How is CIMPLICITY compared to iFIX? |
