Waste Models

Overview

The Waste module helps reduce production waste. It automatically calculates process losses, and other waste sources and allows you to identify waste by amount and reason.

In addition, you can use the Waste applications interactive reports to analyze waste information by amount, production unit, and reason. Again, you get the best possible information in the best possible form.

The Waste Models are the logic that determines when waste is produced and calculates how much waste has been produced. Waste Detection Models process input signals to determine if waste has occurred, the source of the waste, and the waste fault if it is available.

Waste Models 300-303 are site specific Waste Tracking Models. These are not the standard recommended models to use to create Waste Events in Plant Applications today. They are very site specific in the calculations that are used to track waste. It is recommended to use the Generic Models for Waste Tracking.

With Model 304, you can use VB Script to enter logic that determines whether there is waste, and also the location, fault, type, and measurement of the waste.

Waste Models 5011, 5012, and 5014 use pre-configured stored procedures so that you can get up and running quickly. When a tag triggers a Waste Event, Model 5011 writes the information associated with the Waste Event, such as waste amount or fault, to the Waste Event table. Model 5012 finds the nearest event at a specific timestamp and then connects the waste to that event. Like Model 5012, Model 5014 finds the nearest event at a specific timestamp, and then connects the waste to that event, but it can also be triggered by historical value changes, and will either create new waste records or update existing ones.

Log Files

All messages created by models are logged in the Plant Applications Event Manager log files typically in the Proficy\Logfiles directory (this location is a customizable site parameter). The log files are named EventMgr-01.Log and EventMgr-01.Shw with the 01 being the version of the log file. In the "Log" file there will be error messages and in the "Show" file EventMgr.Shw there is a summary of all currently configured models and their current configuration.
