Just to give background on the project.
We have 4 boilers that we are replacing the burners on. I'm planing on using the Vision to control the steam pressure of the boilers. 1 Vision per boiler . So just a basic modulating control. I'm also looking to program a warm up mode so we don't bend the boiler by running it in full fire when it's cold, we need to bring them up kind of slow. I'm also looking to tie into the combustion controller and monitor status and alarms . Also looking go through a gateway so building automation system can monitor the state of the boilers also. The site had gas meters on each boiler to begin with and are being replaced with the QA's . As of right now the customer is happy with the mechanical display on them but would like add real time flow readings on the BAS. They are also looking at adding steam flow meters on each boiler, so they can see how much steam they are producing vs how much gas they are using. Sooo I'm trying to do all this with a Vision 700. I just need to figure out how to get the gas flow reading as the rest I think I can work through. And no the meter does not have M-bus from what I saw . I will double check the next time I'm there. If it does I might just run that through a gateway, I just don't like having to many gateways . Already will need to go from Modbus to Bacnet.
