Downtime Models 200, 210, 211, 212

Overview

The downtime detection models are the logic that determines when the line is running and when downtime is occurring.  Detection models process input signals to determine if the production line is down, the source location of downtime, and the downtime fault. The fault can then be used to default the cause reasons for a particular downtime event.

Model Descriptions

There are 5 Downtime models (2 standard models and 3 model templates). You cannot edit the standard model 200, but you can edit the logic in the model templates for Models 210, 211, 212.

Downtime Model Type

Description

Produces Delay When Not (Running) Model
(Model 200)

This is a standard Downtime model. It determines downtime based on the input tag that you select. While you cannot edit this model's logic, you can set its properties. Since you can only edit this model's properties, it does not appear as a model type in the Downtime Model Builder.

Faults Occur On Single Location
(Model 210)*

This model determines downtime based on a single location only. The location is either running or not running, depending on the VBScript that you enter. To use this model you must have only one location defined. When you have only one location defined, this model is the only option enabled on the Downtime Model Builder

 

Cause Location Determined Directly From Inputs
(Model 211)*

This model determines downtime by checking various locations to determine if the production line is up or down. It determines the location based on input tag values.

Cause Location Determined by Defining Equipment States
(Model 212)*

This model determines the cause location by defining the states of each location (or piece of equipment) along the line. Based on how you define the state of each location, the downtime detection model (as opposed to the control system) attempts to determine which piece of equipment along a line was the source or cause of downtime.

* Maximum # of tags:  500
