This graphical or tabular display presents a ap pipeline system. Bidirectional station displays could be managed by the addition of dynamic directional indicators. Alarm Summary Displays Alarms are indicators 1615 abnormal or unexpected conditions in the system for which the controller is notified through the alarm management system. Text objects typically display dynamic effects in one of two ways: The STM limitation does not mean that only seven, plus or minus two, points or symbols should be on a display.
Display design refers to the way information is arranged and presented on a monitor. API does not represent, warrant, or guarantee that such products do in fact conform to the applicable API standard. Pricing and availability subject to change without notice. Deciding what information to display depends on the purpose of the display and the tasks it will support.
If the point is normal, but has abnormal data attributes, the normal state becomes visible. The interface apj allow 1165 correction and recovery while protecting the application from catastrophic user errors. Labels may be text, numeric, alphanumeric or apl combination. This prevents a misplaced mouse click from operating a field device. Often times, selecting a poke point for an object is navigation to another display.
Control Room Management Best Practices
Window scaling may be used in this scenario to prevent clipping or truncating data. When flow was detected, the pipe symbol might be green.
Display call-up times of one second or less are typical while the Rrp system is under a normal processing load. This display illustrates detailed functionality for a specific station, including equipment status and analog data. It is good practice for owners and operators of pipeline systems to periodically review their SCADA displays for accuracy. Types of menus might include pull downs, pop ups, button bars, and dedicated display menus.
R display presents greater equipment detail and additional operational or point information, etc.
Other factors to be considered when formatting text include the following: This display could be designed with navigation buttons for access to individual station displays. An example of this is demonstrated in Appendix A The presentation of materials at right angles and in vertical or horizontal groupings is easier to look spi than curved or angled visual images.
The exact number should be chosen based on expected controller workload, the number of displays to be viewed concurrently, and how much information can be clearly presented on each monitor. The real-time value is erroneous and could therefore cause confusion or miscalculations.
API RP 1165 Recommended Practice for Pipeline SCADA Displays
The selection area for poke points should be of sufficient size such that objects or buttons can be accurately selected. Ideally, messages require no transformation, computing, interpolation, or reference searching.
The text does not typically change when the value changes.
Returns — All returns must be pre-approved by calling the IHS Customer Service Department at for information and assistance. Formatting techniques should be applied consistently throughout all displays. A database point can have one or many of the appi attributes listed at the same time. Naming conventions including equipment tags, station names, and other identifiers between the control center and remote locations should be standardized.

It can be useful to have displays available for documentation and training purposes that show dp of data attribute hierarchies and display techniques. It is acceptable to indicate the flow state in a pipe symbol with color. FOREWORD Nothing contained in any API publication is to be construed as granting any right, by implication or otherwise, for the manufacture, sale, or use of any method, apparatus, or product covered by letters patent.
An initial step in this process might include vendor supplied training on the capability of their software and available navigation techniques. Exercise caution not to overuse coding, as it can then lose its effectiveness.
Synonymous with navigation buttons, poke points, poke boxes, etc. Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least every five years.
