Operation of controllable field devices is normally not allowed from this display.
When designing a display each element on the display should be examined with respect ro how it impacts controller behavior.
A poke point that is too small can lead to frustration when trying to select an object. In this example, multiple data attributes follow the documented data attribute hierarchy with the exception of the tag attributes.

Keyboards are used to enter instructions and data via keys. Each display could be unique based on the database record type. Call for more information. These theories attempt to describe how people tend to organize visual elements into groups or unified wholes when certain principles are applied. Examples 1156 navigation techniques include, but are not limited to, menus, button bars, hot spots, and navigation buttons.
Projection systems in control rooms are typically overhead projectors that present the image on a wall mounted monitor and are driven by one of the controller ep computers. A system which is a combination of computer hardware and software used to send commands and acquire data for the purpose of monitoring and controlling.
Informational displays include summaries for database information, event logs, trends, etc. Most participants operate crude, product, chemical, and natural gas pipeline systems. This graphical or tabular display presents a single pipeline system. With respect to particular circumstances, local, state, and federal laws and regulations should be reviewed. Naming conventions including equipment tags, station names, and other identifiers between the control center and remote locations should be standardized.
Communications Summary Display Communications summary displays are typically used to provide an overview of the current state of communications between the SCADA system and the field remote.
The following traits should be kept tp mind: Typical summary displays include database, alarm, event and communications. The placement of the label should be consistent with respect to the symbol or text it is labeling, and should have enough separation to be easily discriminated from surrounding fields.

Enumerating or presenting information in numeric, alphabetic, or chronological order also helps an individual mentally associate groups of information.
Another benefit of coding is that 115 helps bypass some of the STM limitations. Some filter examples include filtering on date, pipeline system, remote, or point name. Larger objects and objects placed on the top and the center of the display tend to have more importance than others. Large-screen rear-projection systems are also used in a similar fashion.

Display refresh rates are intervals of time specified for data to update on a display. The information in Appendix A1 shows examples of color and text object characteristic changes for pump and valve states.

The grid below then illustrates the device in typical valid states and typical data attribute combinations. Filtering and sorting may be provided on timestamp, pipeline system, remote, point name, point description, and message text.

It is common industry practice to use color and text as the primary object characteristics to display object dynamics. When flow was detected, the pipe symbol might be green. Additional examples are shown in Appendix A1.

Either method is acceptable. Blink rates beyond human thresholds for detection gp not 1156 good codes. A controller can reference these displays if they are uncertain of a specific display technique.
Summaries also typically include statistics showing 11655 performance e. No part of this work may be reproduced, stored in a retrieval system, or transmitted by any means, electronic, mechanical, photocopying, recording, or otherwise, without prior written permission from the publisher.
A traffic light is a good example—red indicates stop, unsafe and danger; yellow indicates hazard, caution potentially unsafe; and green indicates go, safe, OK to proceed.

Safety, integrity, and security are the primary concerns with any remote or handheld SCADA device interface, especially when allowing remote access using wireless technology. Examples of input devices used for entering information into a computer include keyboard, mouse and track ball, touch-sensitive screen, control-grip and joystick, graphics tablet, and voice recognition device.
Special order items, electronic documents, and age-dated materials are non-returnable. An example is an analog setpoint.
