MLCNVConECAT

Description

This function will connect the output of a pipe convertor block to an EtherCATEtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs Output (Rx) PDO object. The output value of the convertor block will then be written to the PDO object every update of the convertor block. The pipe block is specified by the BlockID input and the PDO object is specified by the DeviceAddr, Index, and SubIndex inputs.

BlockID	Description	The convertor block whose output value will be written to the PDO object. For example: PipeNetwork:CNV1
	Data type	DINT
	Range	n/a
	Unit	n/a
	Default	—
DeviceAddr	Description	The device address of the PDO object to be written. EtherCAT devices are numbered in order with the first device being 1001, the second 1002, etc.
	Data type	INT
	Range	n/a
	Unit	n/a
	Default	—
Index	Description	The index of the PDO object to be written. The index can be determined from the table located in the “PDO Selection/Mapping” tab of the EtherCAT device page. (In Project Explorer, under EtherCAT, select the device, then select the PDO Selection/Mapping tab.)
	Data type	UINT
	Range	n/a
	Unit	n/a
	Default	—
SubIndex	Description	The sub index of the PDO object to be written. The sub index can be determined from the table located in the “PDO Selection/Mapping” tab of the EtherCAT device page. (In Project Explorer, under EtherCAT, select the device, then select the PDO Selection/Mapping tab.)
	Data type	USINT
	Range	n/a
	Unit	n/a
	Default	—

Default (.Q)	Description	Returns TRUE if this function has successfully connected the output of the pipe convertor block to the EtherCAT Output (Rx) PDO Object. See more details here
	Data type	BOOL
	Unit	n/a
