Purpose of automatic stop groups
The settings in the Automatic stop groups module determine how automatic stops are visualized in Plant view, Event board and Reports, and if stops are taken into account for the calculation of operator efficiency and OEE metrics.
Plant view
The automatic stop group defines the border and header color of the machine card, as well as the abbreviation and pattern shown in the header in case an automatic stop occurs. If no automatic stop groups are defined, the machine card displays only a thin red border, and the header shows no abbreviation or pattern. See also Machine cards.
Example: This also shows automatic stop related report items. Automatic stop time started counting at the start of the automatic stop and will be reset when the machine runs again or if a declaration is entered.
Plant view will show the previous automatic stop group name for automatic stops that were initiated before the change, but will show the new automatic stop group name for new occurrences of the automatic stop.
Event board
The main automatic stop group is shown in the tooltip when hovering a stop event: Group. Example: The stop 'Selvedge stop' was classified in the main automatic stop group 'Yarn stops'.
Event board will show the previous main automatic stop group name for automatic stops that were initiated before the change, but will show the new main automatic stop group name for new occurrences of the automatic stop.
Reports
The automatic stop group defines the text and location of the tree branches in the Group type column in the Stop overview visual. (Stops tab)
Example: The branches Yarn stops and Selvedge stops have been defined in the Automatic stop groups module.
When you add groups and rules, or change them, the tree in the Group type column of the Stop overview report will follow these changes.
Calculations
For each automatic stop group, the following settings can be configured:
Operator related: When this checkbox is enabled for a main automatic stop group, the stops in this group are included in the calculation of the operator efficiency. These groups are shown under the Operator stop branch in the Stop overview visual (see previous image).
OEE type: These options define whether the stop should affect the OEE availability metric.
Changes to these settings only affect future calculations. Historical data will remain unchanged, even after settings are added or modified.
How are automatic stops defined?
Automatic stops are defined differently depending on how the machine is connected.
Data Unit connected machines
You define the possible automatic stop texts that are relevant for you in the Stop reason texts module: in the top right corner, click Setting and then under BMSconfig, select Data Unit setup. Then click the Add stop reason texts button 
.
When a machine stops, its machine signals take on specific levels. The combination of these signal levels determines the type of stop. These signals are connected to the digital inputs of the Data Unit (DU). In the Data Unit setup module, a BMSvision installer maps the stop texts to the corresponding machine signal combinations. Signal combinations that are not relevant can be grouped under a fallback stop text.
Vandewiele carpet machines
Automatic stops are defined by Vandewiele and to Connect, a default set of automatic stop groups is automatically provided. This set covers the most typical stops that can occur with Vandewiele machines, but you can add any other stops that appear. The default automatic stop groups definitions are organized in a particular way, but you can re-organize them to fit your needs.
What are groups and rules?
In the Automatic stop groups module, automatic stops are organized into main groups (1), which act as categories, and subgroups (2), which group similar stops.
Each subgroup contains automatic stop group rules (3), which determine which automatic stops are classified into that subgroup. You must select one or more machine types for which the rule applies (4). If only one machine type is selected, the left pane shows the corresponding icon. If multiple machine types are selected, the left pane shows the folder icon. (5) You can use standard operators (such as equals or contains) or regular expressions, for example to apply logical conditions. (6)
How to find automatic stop texts?
For Data Unit connected machines, you can view all stop texts that have been defined in the Data Unit setup module (under BMSconfig in the Settings): click the Add stop reason texts button . Example:
For Vandewiele carpet machines, you can review automatic stops that are not yet captured by the rules in the Automatic stop groups module. To do this, click the Stop groups preview button 
and select Automatic stops.
This page lists all automatic stops that have been received from machines in the past. Stops that do not match any rule are placed in the Default group at the bottom (you can rename this group in the previous screen by clicking its Edit button 
).
Previewing stop groups
The Stop groups preview helps you to define automatic stop groups. Click the Stop groups preview button 
in the Automatic stop groups module. The Stop groups preview consists of two view.
Automatic stops
This page shows all automatic stops that have ever occurred and groups them according the actual automatic stop group settings, including for which machine types these apply. If you change grouping or rules, this view will be updated accordingly, so this is a testpage.
Rules
This page shows the main groups and subgroups with the rules that are defined, and for which machine types these apply.
Creating automatic stop groups
To create a main automatic stop group:
- Make sure that no group is selected (to unselect, click the selected group).
- Click the Add stop group button
.
To create a subgroup:
- Select a main group.
- Click the Add stop group button .
Group settings
In both cases, following dialog is shown:
In case of a subgroup, these settings are used for the automatic stops that are included by its rules.
In case of a main group, these settings are not used.
| Group name* | Any name that if relevant for you for reporting. |
| Abbreviation * | 5-character identifier to be shown on the machine card in Plant view for all automatic stops in the group. |
| Color | Defines the background color of the machine card's header when an automatic stop of this group occurs. Helps to quickly identify the kind of automatic stop. |
| Pattern | Defines the line pattern to be shown on the machine card's header and helps to quickly identify the kind of automatic stop. |
| OEE type | Determines whether the automatic stops in this group should impact the OEE availability metric. Three types are used:
Proper type selection is crucial for accurate OEE calculations. Misclassified stops may lead to incorrect availability figures. |
| Operator related | Select if the automatic stops in this group must be taken into account to calculate the operator efficiency. Is only shown for main groups. |
* = required fields (other fields get a default value)
Nesting
Main groups and subgroups are technically the same type of group. Their role is defined only by their position in the left pane:
A group at the top level is a main group.
A group placed inside another group becomes a subgroup.
You can freely reorganize groups:
Moving a subgroup out of a main group turns it into a main group. It's settings will be ignored.
Moving a main group into another main group turns it into a subgroup. It's settings will be used for the automatic stops that are included by its rules.
Processing order
When an automatic stop occurs, the system evaluates the groups and their rules from top to bottom until it finds a match. Once a rule matches, the stop is classified into the corresponding subgroup. If no rule matches, the stop is classified in the fixed Default group at the bottom (6). The name of this group can be changed.
The position of main groups and subgroups can be changed by dragging them with their handle 
. The Default group cannot be repositioned.
Defining automatic stop group rules
For each subgroup, specify the automatic stop texts that should be assigned. You can create as many rules as needed, but aim to use the available operators efficiently to minimize the total number of rules.
- Select a subgroup.
- Click the Add automatic stop group rule button
. - Select an Operator (see table below) and select or enter a Value.
- Select the Machine types of which the automatic stop texts should be assigned to this subgroup.
| Operator | Description | Value |
| Equal | Matches when the stop text is exactly the same as the defined value. | Select a stop text. |
| Not equal | Matches when the stop text is anything except the defined value. | Select a stop text. |
| Contains | Matches when the stop text includes the defined value anywhere. | Type a string. |
| Starts with | Matches when the stop text begins with the defined value. | Type a string. |
| Regex | Matches when the stop text fits a regular expression. Regex can help you to limit the number of rules. Example: 'Warp OR Weft' matches all stop texts that contain either Warp or Weft (e.g., Warp stop, Weft broken). | Type a regular expression. See Regular expression for more information. |
| Match all | Matches all stop texts. This operator is usually used in the last subgroup (for example, named "Undefined Stops") to capture any stops that were not matched by the preceding subgroups, so when this is defined, there will be no automatic stops in the Default group. | No value required. |
