Hey fellas,
Customer had originally requested our services to check the tank levels of 8 tanks then provide a permissive to two Worldwide Drives (junk). Well after completing the task the other contractor involved failed to automate the entire system from the worldwide drive as promised so it has now been requested that I handle this. We had a micro 1400 out there which with a bunch of expansion I could probably get it to work to run the site however the enclosure it resides in has no more space for terminal blocks (required) and given the size and requirements of the application, we need to get a more suitable controller. Long story short we are now spec'ing out a new enclosure with a new controller (thinking L33) but we may have a need for either Flex IO or Point IO to handle roughly...
DI's - 47
DO's - 15
AI's - 2
AO's - 1
We also have 8 devices that communicate via modbus (can also communicate hart if needed) and 3 flow meters that communicate via hart.
I am leaning towards FLEX I/O to handle this process given that Point I/O has a max density of 8 and I would like to cut back on expansion cards. (thinking prosoft or HCS for Hart but throwing ideas around)
Given your experiences, what pro's and con's have you seen from Point I/O and Flex I/O? Where do you see one succeeding over the other and vise versa? Just trying to get some feedback from other point of views in the industry before I start developing this new control strategy.
Thanks fellas, I appreciate your feedback.
