 Utility Configuration

Create a new class of utilities to use the C.R.O.. The data required to operate the project is extracted from

these controllers. Open the "Class" menu and create a class including the utilities of interest. Utilities are

those with the saturation pressure set-point in common.

Use the Create/Edit/Delete menu items to modify the utility classes. Each utility class can and must be

assigned to one of the CRO engines. The use of the same class applied to multiple engines is not permitted.

Access the menu OperationParameters Engine relative to the desired CRO engine to set the configuration

parameters. The C.R.O. module, to better manage the availability of cooling power, in time, modifies the set-

point of the compressor plant (typically, for utilities in normal temperature mode).

- Execution interval: indicates how often a new set-point is sent to the plant (in minutes).

- Analysis interval: indicates for how many minutes, in reverse, the data is to be analysed (operation of

class utilities; in minutes).

- Reference class: is the set of controllers affected by the calculation of the worst possible case.

- Device: is the plant controller affected by the modification of the set-point.

- Set-Point: allows you to select which set-point to use: typically, that of the plant suction section.
