| To send data over an established connection, execute TSEND_C with a rising edge on REQ. After a successful send operation, TSEND_C sets the DONE parameter for one cycle |
To establish a connection, execute TRCV_C with parameter CONT = 1 |
| To establish a connection and send data, execute TSEND_C with CONT =1 and REQ = 1. After a successful send operation, TSEND_C sets the DONE parameter for one cycle. TRCV_C operations |
To receive data, execute TRCV_C with parameter EN_R = 1. TRCV_C receives the data continuously when parameters EN_R = 1 and CONT = 1. |
| The following functions describe the operation of the TRCV_C instruction: | To terminate the connection, execute TRCV_C with parameter CONT = 0. The connection will be aborted immediately, and data could be lost. |
TRCV_C handles the same receive modes as the TRCV instruction. The following table
shows how data is entered in the receive area.

1 to 8192 The "ad hoc mode" exists with the TCP and ISO on TCP protocol variants. You set "ad hoc
mode" by assigning "65535" to the LEN parameter. The receive area is identical to the area
formed by DATA. The length of the received data will be output to the parameter
RCVD_LEN.
If you store the data in an "optimized" DB (symbolic only), you can receive data only in
arrays of Byte, Char, USInt, and SInt data types.
Note
Importing of S7-300/400 STEP 7 projects containing "ad hoc mode" into the
In S7-300/400 STEP 7 projects, "ad hoc mode" is selected by assigning "0" to the LEN
parameter. In the , you set "ad hoc mode" by assigning "65535" to the LEN
parameter.
If you import an S7-300/400 STEP 7 project containing "ad hoc mode" into the , you
must change the LEN parameter to "65535".
Note
Due to the asynchronous processing of TSEND_C, you must keep the data in the sender
area consistent until the DONE parameter or the ERROR parameter assumes the value
TRUE.
For TSEND_C, a TRUE state at the parameter DONE means that the data was sent
successfully. It does not mean that the connection partner CPU actually read the receive
buffer.
Due to the asynchronous processing of TRCV_C, the data in the receiver area are only
consistent when parameter DONE = 1.

TRUE irrelevant irrelevant The job is being processed.
FALSE TRUE FALSE The job is successfully completed.
FALSE FALSE TRUE The job was ended with an error. The cause of the error can be found
in the STATUS parameter.
