MLCNVConECAT

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Connects the output of a pipe convertor block to an EtherCAT ***EtherCAT 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 PDO is a type of protocol frame used in some fieldbuses. A PDO contains one or more object dictionary entries, which define the application data transferred between devices. object.

Inputs

Input	Data Type	Range	Unit	Default	Description
BlockID	DINT	No range	N/A	No default	The convertor block whose output value is written to the PDO object. Example: PipeNetwork:CNV1.
DeviceAddr	INT	No range	N/A	No default	The device address of the PDO object to be written. EtherCAT devices are numbered in order. The first device is 1001, the second 1002, etc.
Index	UINT	No range	N/A	No default	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.
SubIndex	USINT	No range	N/A	No default	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.

Outputs

Output	Data Type	Range	Unit	Description
Default (.Q)	BOOL			Returns TRUE if this function has successfully connected the output of the pipe convertor block to the EtherCAT Output (Rx) PDO Object. See Pipe Network - General Rules for more information.

Remarks

• The output value of the convertor block is written to the PDO object every update of the convertor block.
• The pipe block is specified by the BlockID input.
• The PDO object is specified by the DeviceAddr, Index, and SubIndex inputs.
