WriteMemory (FB)¶

FUNCTION_BLOCK WriteMemory EXTENDS CBM.ETrigA

This function block is for writing the memory of EtherCAT slaves.

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	xExecute	BOOL		Rising edge: Action starts Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (xDone, xError, iError) are present at the outputs for exactly one cycle.	ETrigA
	xAbort	BOOL		TRUE: Action is stopped immediately and all outputs are reset to their initial values.	ETrigA
Output	xDone	BOOL		TRUE: Action successfully completed	ETrigA
	xBusy	BOOL		TRUE: Function block active	ETrigA
	xError	BOOL		TRUE: Error occurred, function block aborts action FALSE: No error	ETrigA
	xAborted	BOOL		TRUE : Action aborted by user	ETrigA
Input	usiCom	USINT	1	index of master 1: first Ethercat master
	wSlaveAddress	WORD		address either auto increment address or physical address of device
	xAutoIncAdr	BOOL		flag that determines which way to use the given address
	xBroadcast	BOOL		flag if broadcast read should be used, if true then wSlaveAddress and bAutoIncAdr are not used
	uiMemOffset	UINT		offset of memory
	iSize	INT		bytes to write
	pSrc	POINTER TO BYTE		buffer to data that should be written
	udiTimeOut	UDINT		Timeout for operation in ms
Output	uiWorkingCounter	UINT		working counter of received command
