I've brought this up before, but did not come to a conclusion about what to do.
I have a large number of tags used on a re-branded Red Lion HMI project. For those with experience with this, I'm trying to figure out if it would be worth my time to change how I'm reading and writing my tags in order to cut down on my latency.
This was my first HMI project using Red Lion. When I saw how easy it was to "Add a Block" under my device and then attach a tag to the address, I decided that was the best way to do all of my tag addresses. I added blocks from the SLC 5/05 to read and write, as well as the 6 Eurotherm Mini 8 loop controllers. I wasn't sure how to determine the best update rate for each tag, so I left them at the default of Auto... continuous update of read tags, and write only when the value is changed. You can get a feel for how everything from my attached picture.
When it was done, I was disappointed to find how much latency there was. There are switches to turn on pumps that you have to hold for at least 10 seconds before the pump turns on. This is not detrimental to operating the machine, but it's embarrassing to me. At first I asked Red Lion for input. The tech support person was helpful, but when he asked to look at my file, he saw that it was a re-branded version of Crimson, and he directed me to Eurotherm tech support... which was a waste of time.
I'm planning an addition to the HMI, and with a little extra time right now, I'm thinking about attacking the latency issue. My first thought is that I have to get rid of the block reads and just assign each tag individually to the device/address where it goes. With the large number of tags, this will probably take a couple of hours to do.
For those with more experience with Red Lion, do you have thoughts or suggestions about this latency issue?
The rebranded software is called GUIcon: https://www.eurotherm.com/download/guicon-version-2-0-software-package-gold-build-683-003/
...I see it's in the discontinued products section. Ugh.
