Hi sedgy,

It is not my job to wire and set-up the communication.
Unfortunately, here we are a very small staff: it is enough to do what is strictly needed but if you want to go a bit further you get to do a bit of everything.

In this case I am just trying to understand where the problem is and what can be done to solve it beacuse the Automation contractor says the problem is on the chiller while the refrigeration contractor says it is on the DCS... it is not a vital issue as we run the chiller on time bands with two different set-points, so the process is not affected at all by this comm problem.

I want to have total control of the chiller from the DCS so that we can achieve a more precise regulation of the set-point in relation to the particular production step: this would then result in saving a significant amount of power every week by increasing the T set-point whenever possible. Time bands are great but are not too flexible.
