Help: Does anyone know if the Honeywell PKS system has a moving average block?
Thread Content
As the title suggests: Does anyone know if the Honeywell PKS system has a moving average function? I’m looking to calculate the 8-hour real-time average of a product’s extraction rate, and I don’t want to use the system’s built-in 8-hour average function (which uses a small number of sampling points). Thank you.
Integrate and then take the average, that is, accumulate and then compute the mean; you can give this approach a try
Thank you for your answer. I have done this in the Foxboro system, but it requires many registers; generally, the number of registers available in calculation blocks is limited, so several calculation blocks need to be used. I have used moving average blocks in Yokogawa’s Vp system, so I was wondering if there are similar modules available within PKs.
Thank you all for your thoughtful contributions. After several days of searching for relevant information, I found a module for calculating moving averages – the rollavg function block. It allows one to set the sampling interval as well as the period over which the average is calculated (up to 1 hour). I would like to share this experience with you all.
