Description

Receive UDP packets from the specified remote host. Use the UDP Receive block to output the UDP packets received as one dimensional array of size defined in Data size parameter. Use UDP Receive block for stateless, connectionless, and byte oriented data transmission.

You can specify the remote UDP host in the Remote IP address (0.0.0.0. for accepting all) parameter to send the UDP packets to the local UDP host specified in the Local IP Port parameter.

The status port on the block indicates if the data is good or not.

The different values returned by the status port are as follows:

0 - represents no error in data reception

1 - represents an error in data reception.

Parameters

Local IP Port

Enter the local UDP host IP port to receive UDP packets.

Remote IP address (0.0.0.0 for accepting all)

Enter the IP address of the remote UDP host in 0.0.0.0 format to receive UDP packets. For accepting data from any valid IP address, enter ‘0.0.0.0’.

Data type

Select the data type of the UDP packets.

Data size (N)

Enter the data size of the data type you have selected in the Data type parameter.

Wait until data received

Select this check box to receive a UDP packet only after the previous packet is received to avoid data overlap.

Sample time

Specify how often this block should read the port buffer. Enter a value greater than zero.

This value defaults to a sample time of 0.01 seconds. Smaller values require the processor to complete the same number of instructions in less time, which can cause task overruns.
