Execution Path-Path Schedule
The Path Schedule allows configuration of the process order statuses and the valid transitions for each individual status. The number of process orders that can have a specific status can be configured. The automatic changes for statuses can be set for completion of a process order. The specific type of schedule alarming can be configured including the threshold values and the threshold type. These alarms are handled by the Schedule Manager service.
Terms and Definitions
Schedule Status Transitions: The allowable status changes from a specific status that can be selected for a process order in the Schedule View display.
Status Order: The order statuses are shown in a process order on the Schedule View display. Select a status and click Move Up or Move Down to change the order.
How Many: Determine how many process orders are allowed with the selected status. For example, if the Active status is selected and you type 5 in the box, then you can have a maximum of five process orders with the Active status displayed in the Schedule View.
Auto Promote From: Promote from a certain Status when a certain Process Order Status is changed. Example: When a Process Order is changed to Complete then promote a Pending process Order to Active. Auto Promote From would be Pending and Auto Promote To would be Active for the Complete Status.
Auto Promote To: Promote to a certain Status when a certain Process Order Status is changed. Example: When a Process Order is changed to Complete then promote a Pending process Order to Active. Auto Promote From would be Pending and Auto Promote To would be Active for the Complete Status.
Sort With: This will group process orders with the status that is selected in the Sort With list with process orders that have the status that is selected in the Status Order list. Furthermore, if Enable PO Ordering has been enabled for the status, process orders can be moved forward or backward between the two groups in the Schedule View display. For example, if the Underproduced status is selected in the Sort With list and the Pending status is selected in the Status Order list, then process orders with the Underproduced status will be grouped next to process orders with a status of Pending. Furthermore, if the status, Complete, has a valid transition of Underproduced, and the status Underproduced was selected to sort with the Pending status, then when the process order was transitioned from Complete to Underproduced, the process order would be grouped with the other Pending process orders.
To Configure the Schedule Status Transitions for an Execution Path
Expand
Plant Model and expand the desired department.
Right click the desired production line and select Configure Execution Paths For <line name>.
Go to the Path Schedule tab.
Select the Status Transitions tab.
Under the Status Transitions For This Path select each status one at a time in the Items With This Status window.
Click the single arrow < to add individual Valid Transition Statuses for the selected status to the Valid Transition window.
Click the single arrow << to add all Valid Transition Statuses for the selected Status to the Valid Transition window.
Click the single arrow > to remove individual Valid Transition Statuses for the selected Status from the Valid Transition window.
Click the single arrow >> to remove all Valid Transition Statuses for the selected Status from the Valid Transition window.
To Define The Valid Status Transitions:
Browse to the Plant Model and select the desired Production Line; right click and select Configure Execution Path from the menu.
Select the Path Schedule tab.
Select the Status Transitions tab.
In the window named Status Transitions For This Path, click on a status in the far left window called Items With This Status.
Set the Status transitions that are acceptable as transitions to and from this status in the Valid Transition window. Move the Valid and Invalid Transition Statuses to the desired window using the various arrow buttons.
Click the Close
button to exit the Unit Properties Configuration dialog box when completed.
Alarms
To view these alarms on the Alarm display, you must select this unit on the Units tab when configuring the Alarm display. For more information, see the topic, Configuring an Alarm View Display.
Schedule Countdown Quantity Alarm: Alarm is triggered when the Quantity left to complete a specific Process Order is within the Threshold Value. The Threshold can be set by % or by the Engineering Units. The priority of the alarm can be set to Low, Medium, or High.
Schedule Countdown Time Alarm: Alarm is triggered when the time left to complete a specific Process Order is within the Threshold Value. The Threshold can be set by a % or by the Engineering Units. The priority of the alarm can be set to Low, Medium, or High.
Schedule Downtime Time Alarm: Alarm is triggered when the amount of Downtime during the running of a specific Process Order exceeds the Threshold Value. The Threshold can be set by % or by the Engineering Units. The priority of the alarm can be set to Low, Medium, or High.
Schedule Overrun Quantity Alarm: Alarm is triggered when the amount of Product being made exceeds the Threshold Value during the running of a specific Process Order. The Threshold can be set by % or by the Engineering Units. The priority of the alarm can be set to Low, Medium, or High.
Schedule Overrun Time Alarm: Alarm is triggered when the amount of time a specific Process Order has been run exceeds the Threshold Value during the running of a specific Process Order. The Threshold can be set by % or by the Engineering Units. The priority of the alarm can be set to Low, Medium, or High.
Schedule Predicted Time Alarm: The Predicted Time is the calculated duration left to complete a process Order. The calculation is based on the amount of good product made and how long it has taken to make that good product and the Predicted Time is extrapolated using the Forecast Start Date and Forecast End Date. The alarm is triggered when the Predicted Time for a specific Process Order is less than the Threshold Value. The Threshold can be set by % or by the Engineering Units. The priority of the alarm can be set to Low, Medium, or High.
Schedule Status Change Alarm: Alarm is triggered when a Process Order is changed to a specific Status. The priority of the alarm can be set to Low, Medium, or High. (Note: Process order alarms gets triggered only when a Process order is in the ‘Active’ status and then transitions to the selected alarm status.)
Schedule Update Alarm: Alarm is triggered when a Process Order is updated. The priority of the alarm can be set to Low, Medium, or High.
Schedule Waste Quantity Alarm: Alarm is triggered when the amount of Waste during the running of a specific Process Order exceeds the Threshold Value. The Threshold can be set by % or by the Engineering Units. The priority of the alarm can be set to Low, Medium, or High.
User Defined Properties
Custom attributes of Process Orders. These can be thought of as extra fields of information or data that needs to be shown for Process Orders. Custom data types can be applied to the field to set the format of the data to aid the end user.
