Present Position Change (DINT)

Name	Present Position Change(DINT): MD_CPU611_SetPosition_DINT

Basic Function	Changes the present position to the specified position data.
Symbol
Originates from	Tsunagi Lab Europe
Created by	OEE-HQ HvB (creation and testing)
File Name	MD_CPU611_SetPosition_DINT.cxf
Applicable models	CPU Unit	CJ2M-CPU Unit version 2.0 or higher with max. two CJ2M-MD211 (NPN) or CJ2M-MD212 (PNP)
	CX-Programmer	Version 9.1.2 or higher
Conditions for usage	None.
Function Description	Changes the present position of the output specified with the Axis No. (Axis) to the value set in Position data (Position) when Start (Execute) is turned ON. The Error flag (Error) will be turned ON and Error code (ErrorID) will be output when an error related to this FB occurs. These statuses, Present position change completed (Done)/ Error flag (Error)/ Error code (ErrorID), will be reset when Start (Execute) is turned OFF. If Start (Execute) was turned OFF before positioning is completed, the status will be set for at least one cycle when a corresponding condition occurs. Note: This FB uses the Change Present Value Function of the CPU Unit. For details, refer to the section of the manual listed in the Related manuals.
Kind of FB definition	Connect Always ON type Connect the EN input to the Always ON Flag (P_ON). The same instance cannot be used in two or more places.
FB Precautions	• This FB cannot be executed during pulse outputs. An error will occur if it is executed. • The origin will be decided when this FB is executed. The MD_CPU* function blocks are offered 'as is' and may serve as a basis for development. Users should previously test its adequacy to the final application. Omron can not be held responsible in case of malfunction.
EN input condition	• Connect the EN input to the Always ON Flag (P_ON). • If a different type of bit is connected to EN, the FB outputs will be maintained when the connected bit is turned OFF.
Application example	Turning the Start trigger from OFF to ON will change the present position of the Pulse output 0 on the CJ2M-MD21* Unit to the specified Position data (Position).

Output Variables

Name	Variable name	Data type	Description
ENO	ENO	BOOL	1 (ON): FB operating normally 0 (OFF): FB not operating normally
Present position change completed	Done	BOOL	Turns ON when Present Position Change is completed normally.
Error flag	Error	BOOL	1 (ON) indicates that an error has occurred in the FB.
Error code (May be omitted)	ErrorID	WORD	The error code of the error occurred in the FB will be output. For details of the errors, refer to the sections of the manual listed in the Related manuals above. When Unit No. or Axis. No. is out of the range, #0000 will be output.
