An INET control system running INET software is normally a quick responding system where accessing point data happens within a few seconds. However, occasionally we run into systems that seem to be running slower than expected – in rare instances, we have experienced systems that take up to 45 seconds or more to access data.
Here are a few examples of what you might experience if your system isn’t fully optimized:
A. Logging into a controller or saving a database (LIU’s are the exception) takes longer than 20 seconds
B. Graphic page data points seem to populate one at a time or question marks appear for an extended time before data is populated
C. Â Accessing data point control from a graphic page takes longer than expected
Although there are many possible causes for this to happen, there are a few that seem to rise to the top which cause network congestion (Bandwidth) and/or slow moving data across the network:
1. Unnecessary and/or redundant Alarms, Messages and Transactions (AMT)
2. Masking of AMT not done systematically
3. Abnormal amount of Indirect points
4. LAN wiring installed incorrectly (Star or “T” configurations) / not grounded properly (At one end only)
5. Links not configured properly
These are only a few of the reasons, there are other and more complex conditions that can cause slow network traffic. The good news is – Future Controls, Inc. has solved these issues on many sites over the years and we are confident we can do the same for your system. If your system could use some optimization, please contact us today for further information and some possible solutions.
We are hopeful this helps and look forward to hearing from you soon!
