  • F28M35x/F28M36x TCP Receive block

Description

Receive TCP packets from another TCP host over the TCP/IP network. Use TCP Receive block for connection-oriented, stateful, and stream based data transmission. Also, the TCP Receive block guarantees the data transmission.

This block outputs data received as an array of the size specified in the Data size 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 IP port number of the local host to receive data.

Data type

Select the data type of the TCP packet.

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 TCP 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.
