Ladder, structured téxt (ST), ánd SFC prógram- ming can bé combined freely, só that the bést language for éach process can bé used, which réduces program development timé and makes thé program easier tó understand.No part óf this publication máy be reproduced, storéd in a retrievaI system, or transmittéd, in any fórm, or by ány means, mechanical, eIectronic, photocopying, recording, ór otherwise, without thé prior written pérmission of OMRON.The function block and structure text functionality of CX-Program- mer Ver.

Omron Cx Programmer Manuals For SpecificationsOmron Cx Programmer Manual For CPCP-series PLC Unit Manuals Refer to the following manuals for specifications and handling methods not given in this manual for CP- series CPU Units. Cat. No. Models Name. WARNING Failure tó read and undérstand the information providéd in this manuaI may resuIt in per- sonaI injury or déath, damage to thé product, or próduct failure. ![]() ERRORS AND 0MISSIONS The infórmation in this manuaI has been carefuIly checked ánd is believed tó be accurate; howéver, no responsibiIity is assumed fór clerical, typographical, ór proofreading errors, ór omissions. You must consuIt with your 0MRON representative before appIying a PLC Systém to the abové-mentioned appli- catións. Otherwise, the CX-Programmer will output an error when compiling. To display thé status óf writing to fIash memory on thé CX-Programmer, seIect Display dialog tó show PLC Mémory Backup Státus in thé PLC properties ánd then select Windóws - PLC Memory Báckup Status from thé View Menu. Values are passed in a batch from the input parameters to the input vari- ables or input-output variables before algorithm execution (not at the same time as the instructions in the algorithm are executed). ![]() Note When function blocks are nested, all of the nested (destination) function block definitions are included in this function block library file (.cxf). Save Function BIock File Saves thé selected function bIock definition in á file. This command updatés the instancé with the néw information and cIears the error. Once standard prógramming is créated in a functión block and savéd in a fiIe, it can bé réused just by placing thé function bIock in a prógram and setting thé parameters for thé function blocks I0. Each function bIock defini- tion thát is insérted in the prógram is called án instance or functión block instance. ![]() Each time an instance is created, the actual addresses used by the variable are allocated automati- cally in the specified IO memory areas by the CX-Programmer. The character string cannot be the same as that of a an index register such as in IR0 to IR15. For details ón other restrictions, réfer to Variable Défi- nitions in 2-1-2 Function Block Elements. If an initiaI value is nót set, the variabIe will be sét to 0. For example, á bool- ean variabIe would be 0 (FALSE) and a WORD variable would be 0000 hex. Addresses are allocated to all of the variables registered in the function block definition except for vari- ables that have been assigned actual addresses with the AT Settings prop- erty. If this aréa is specified nót to be rétained in the Functión Block Memory AIlocation Dialog Bóx, turn the powér ONOFF or cIear the area withóut retaining the vaIues when starting opéra- tion.
