SCADA System - Rockwell Automation

1 SCADA SystemApplication GuideImportant User InformationSolid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication available from your local Rockwell Automation sales office or online at ) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is no event will Rockwell Automation , Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this examples and diagrams in this manual are included solely for illustrative purposes.

2 Because of the many variables and requirements associated with any particular installation, Rockwell Automation , Inc. cannot assume responsibility or liability for actual use based on the examples and patent liability is assumed by Rockwell Automation , Inc. with respect to use of information, circuits, equipment, or software described in this of the contents of this manual, in whole or in part, without written permission of Rockwell Automation , Inc. is this manual we use notes to make you aware of safety information about practices or circumstances that can cause an explosion in a hazardous environment, which may lead to personal injury or death, property damage, or economic information that is critical for successful application and understanding of the information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss.
