Read Handshake (Clock-Driven Logic)
Reads one element of data from a handshake item and automatically removes the data to prepare for the next transfer.
If ready for output is False during a given clock cycle, output valid returns False during that clock cycle.
reference in
Reference to a handshake item. You can wire a handshake control, handshake constant, or the reference out terminal of another Handshake node to reference in.
ready for output
A Boolean that determines whether downstream nodes are ready for this node to return a new value. The default is True. Use a Feedback Node to wire the ready for input output of a downstream node to this input.
| True | Downstream nodes are ready for this node to return a new value. |
| False | Downstream nodes are not ready for this node to return a new value. |
reference out
The same handshake reference wired into this node.
data
The data retrieved from the handshake item. The data type of data is the data type you wire to the Create Handshake node that creates the handshake item.
output valid
Boolean value that indicates whether this node computes a result that downstream nodes can use.
Wire this output to the input valid input of a downstream node to transfer data from the node to the downstream node.
| True | Downstream nodes can use the result this node computes. |
| False | This node returns an undefined value that downstream nodes cannot use. |
Where This Node Can Run:
Desktop OS: none
FPGA: All devices
Web Server: Not supported in VIs that run in a web application
