Great video. I liked that you took the time to show how to create each point!

Hi BAS_Mgr! Thanks for your comment. I hope it was not that confusing, there is a lot going on in that tutorial!

Great video!!! Thanks. Please keep posting they are very useful!

Thanks Michael. I will, soon!

Great video. Do you have one like this but based on runtime?

[@controlshero]

Hi there! Thanks for your comment. No, I don't have a lead-lag video based on runtime. I will put it on my to-do-list! Thanks!

[@therandomchannel6103]

@@controlshero That would be awesome! Thank you! Absolutely no rush! Just being curious

Where’s the CCT part of video?

[@controlshero]

Hi Jager, I don't have the CCT part. My idea of this video was to show how to do a weekly lead/lag in Metasys LCT, and I was assuming that the CCT application was already done, and just needed its Lead/Lag Network Input to be commanded from the NAE. Thanks!

@@controlshero what if we don't have that point in CCT? what is it? I have 3 individual plants so 3 different programs so I would just have the system enable point for each plant? but I don't follow how that relates to the P-Lead point. thank you!

Hi@@jessicaowen-mt1rw Thank for your comment! The idea of this video was to show how to create a lead/lag for 3 system in Metasys, assuming that you already have a CCT application with a lead/lag analog point, where its values were 1, 2, and 3. Or if you wanted to command 3 BOs (e.g. 3 pumps start/stop points) and have each BO being commanded by each Interlock. But in many cases you could have a multistate point, and this would not apply unless you do an extra modification in Metasys or CCT. But this would be more advanced. Well, if you want to lead/lag 3 plants it can be done as well, but you may need to add some modifications as I mentioned. If you want to send me screenshots or more information I can help, you can go to my website www.controlshero.com and send me a message in the contact form. From there, it is easier to communicate via email.

@@controlshero Thank you! I ended up writing to the system enable point and it worked. This video was perfect for what I needed. I think the only downfall was the trigger having to be on then off to work. That was confusing for the facility operators to understand / remember. But we figured a work around for now. Now I'm trying to figure out how to LCT to do a failure rotation. And then staging so a second plant can come on as needed. I tried some interlocks but then it turned on all 3 plants. I'll check out your website.
