1.0 Introduction
The purpose of this document is to provide an understanding and description of the operation of
the Site HMI Station in regards to plant overview, major equipment status, routes selection and
deselection, and etc. The HMI station when started up will run automatically and display the first
overview page with a Title Bar at the top, a major screen display area in the middle and a status
bar at the bottom.
Sample display
Title bar area at the top allowing navigation to major displays such as overview, routing and alarms.
Main screen area showing the overview, routing and various pop up windows.
Status bar at the bottom showing status message of the Factory View Software.

1.1 Scope of control for Site HMI
The Central Office has a ControlLogix (CLX) PLC acting as gateway to all future CLXs in various
Substations. The Central Office CLX now connects to the Central PLC5 PLC and receives
operational status from existing PLC5s. Through a Site wide fiber network, the Central CLX will
be connected to Sub2A HMI Station and a PLC Engineering Work Station. The Central CLX will
not control any equipment but it performs the very important and centralized task of Route
Selection and Interlock.
The Site HMI runs the same Factory Talk View Client application as the Sub2A HMI in the Substation 2A. The Site HMI has the following major components:
- Title Bar
- Site Overview
- Major Equipment Status
- Route Handling
- PLC Status

Message is the descriptive text for the alarm event and the text is configured in the PLC. Changes to this descriptive text must be made in the PLC.
3.4.4 Alarm Class
The Alarm Class is a classification string that is associated with an alarm when it is defined during PLC programming. The Alarm Class provide a user defined string that can be used for filtering and sorting alarms.
3.4.5 Alarm Name
The Alarm Name is the name of the tag in the PLC for that alarm event.
3.5 Navigating to equipment status from Overview
The operator may navigate directly to the status pop up display of an equipment by moving the cursor to over the rectangular name box of an equipment and then click and release. For examples, if one wants to navigate to the status page of CV316, the operator should move the
cursor over the CV316 rectangular box and click to navigate to the CV316 status page. As the cursor moves over the rectangular box, the name box is highlighted with a thicker border so that the operator knows the cursor is sitting over it.

5.0 Route Handling
Route selection may be carried out in either the HMI Station in the Central Office or in individual Substation. The idea is to offer the maximum flexibilities to the operation of the plant while maintaining the maximum integrities and safety in route selection. This is done by centralizing the route interlocks in the Central ControlLogix PLC with route selection requests made from every substation. Route selected and running are shown in the route status table so that operator is made well aware of the present route status before he make any route request. When the operator makes a route request, a small map will pop up showing the requested route. Confirmation pop up will be shown once the operator presses either the Select or Deselect button.
5.1 Accessing the Route Selection Table
There are two ways to access the Route Selection Table:
1. Direct from Title Bar
2.1 From the Navigation Pane
2.2 Press for Route:

5.2 Route Selection Table
In either case of the above accessing methods, the following table will be shown in the main display area of the HMI:
The routing table is comprised of two portions: a matrix of the the first 4 columns and 3 rows, and the 5
th column.
For the first matrix, the 4 columns denotes the 4 stacker/reclaimers and the rows refer to three operating modes of the SRs.
The much simpler second matrix is dedicated for selection of the ship loaders S400 and S401.
For each Route Request Button in the Route Table, the top line describes the route and the bottom line refers to the number of that route.
The title of the Title Bar will show “Route Selection”
The present route status for Substation HMI will be shown by pressing this button
Route request buttons to make route selection or de-selection request.
The boundary of the button – Green when that route has been selected and running, Grey when inactive
