Notice:OMRON products are manufactured for use according to proper procedures by a qualified operatorand only for the purposes described in this manual.The following conventions are used to indicate and classify precautions in this manual.Always heedthe information provided with them.Failure to heed precautions can result in injury to people or dam-age to the product.DANGERIndicates information that,if not heeded,is likely to result in loss of life or serious injury.Additionally,there may be severe property damage.△WARNINGIndicates information that,if not heeded,could possibly result in loss of life or seriousinjury.Additionally,there may be severe property damage.CautionIndicates information that,if not heeded,could result in relatively serious or minor injury,damage to the product,or faulty operation.OMRON Product ReferencesAll OMRON products are capitalized in this manual.The word "Unit"is also capitalized when it refers toan OMRON product,regardless of whether or not it appears in the proper name of the product.The abbreviation "Ch,which appears in some displays and on some OMRON products,often means"word"and is abbreviated"Wd"in documentation in this sense.The abbreviation "PLC"means Programmable Controller and the abbreviation "PC"means personalputer and are not used as abbreviations for anything else.The abbreviation "PMSU"means Protocol Macro Support Unit and refers to the CommunicationsBoard for the C200HX/HG/HE.Serial Communications Board for the CS.and Serial CommunicationsUnits for the CS/CJ.Visual AidsThe following headings appear in the left column of the manual to help you locate different types ofinformationNote Indicates information of particular interest for efficient and convenient opera-tion of the product.1,2,3...1.Indicates lists of one sort or another,such as procedures,checklists,etc.TABLE OF CONTENTS1Intended Audience...................................................XXiv2General
