OpFcn OP7160EX1 DataIn Send




The block OpFcnOP7160EX1 DataIn Send is used to transfer raw data from an RT-LAB model to an Opal-RT OP7160 card.

One OpFcnOP7160EX1 DataIn Send block controls data transfer to one of the DataIn port of the bitstream programmed in the OP7160 card. The OP7160-EX1 bitstream must be produced with Opal-RT RT-XSG product, version 2.1 or higher.

In the OP7160-EX1 implementation of the OP7160 support, the OP7160 bitstreams have 32 DataIn input ports and 32 DataOut output ports. Each port has a maximum width of 250 32-bit data words. These data ports are used to exchange data between the RT-LAB model and the FPGA chip of the OP7160 via the PCIe bus of the target computer.


Controller NameBind this block to an OpCtrl OP7160EX1 block by entering the same 'Controller Name' as specified in the OpCtrl OP7160EX1 block The OpCtrl OP7160EX1 block controls initialization of the settings of one specific OP7160 card in the system.
DataIn port numberEnter the number of the DataIn port to be controlled by this block, in the range [1:32].
Data inport widthEnter the maximum number of data words that will be transferred to the OP7160 at each calculation step, in the range [1:250].
Data inport typeSelect the OpFcnOP7160EX1 DataIn Send data inport type : 'uint32' or 'double'. When 'double' is selected, the underlying driver performs data typecast between 'double' and 'uint32', so data values are limited to the range [0:2^32-1]. The possibility to set the inport to 'uint32' type is provided for optimum performances.


The block has one inport. The data values routed to this inport are transferred to the OP7160 at each calculation step. No scaling or formatting of the data is performed, except for typecast from 'double' to 'uint32' if the 'Data inport type' parameter is set to 'double'.


The Status output returns the following values:

0No error.

Block could not be matched with an OpCtrl OP7160EX1 block (check the 'controller Name' value), or OP7160 card initialization problem.

-2Internal memory initialization problem.
