Reads from memory available on the FPGA target.
Reference to the memory item.
Memory address to read from.
The valid address range depends on the requested number of elements you specify when creating the input memory item. For example, if you specify a requested number of elements of 65536, the valid address range is 0–65535. If address exceeds the address range, this node returns an error.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Reference to the memory item.
Data retrieved from the specified address of the memory item.
Error information.
The node produces this output according to standard error behavior.

On the Item tab, use the Memory interfaces option to configure the interface (A or B) that this node reads from. Depending on the read/write access you configured when creating the memory using the Create Memory node, select an appropriate interface using the following guidelines:
Where This Node Can Run:
Desktop OS: Windows
FPGA: All devices
Web Server: Not supported in VIs that run in a web application
