In a good, consistent alarm system, annunciations will be few and alarm limits will outline a Window of Best Operation, acting as a guide to the operator for achieving process objectives. The operator takes action to achieve business objectives and in response to changes in process capability due to abnormal
Text Substitution on File Read Some process historians very usefully record data for some status variables as text such as ON or OFF, OPEN or CLOSED instead of as integers. Laboratory data similarly can contain text such as PASS, FAIL. CVE 2.8.0 and earlier treat text fields as invalid data.
We regret to have to raise the purchase price of our CVE product by approximately 9% due to inflation. This is the first price increase for CVE in many years and will apply from 1 February 2023. TAP subscriptions will be affected at next renewal. The rise may be avoided

The best thing you can do right now to improve your batch analysis is making sure that the batch number and phase number are captured in your plant historian.
This three-way relationship between Operating Objectives, Operating Envelope, and Process Capability is why you must use CVE for alarm performance monitoring.
When we start exploring data in CVE, there are often some variables that are single-valued, that is, all of the data has been reported as the same value.

Most of the operator alarm problems today arise from incorrect alarm limit values. Plants assume that they are independent of each other – which they aren’t.
The simple answer is yes! CVE lets you pursue individual variable objectives. Read about how this is achieved here.
For start-up control CPM guides the process operator to stay within the envelope of a combination of your best previous start-ups and the start-up procedure.
