Reference to the associated connection. ID must be identical to
the associated parameter ID in the local connection description.
Value range: W#16#0001 to W#16#0FFF
LEN IN UInt Maximum number of bytes to be sent (TSEND) or received
(TRCV):
 Default = 0: The DATA parameter determines the length of the
data to be sent (TSEND) or received (TRCV).
 Ad hoc mode = 65535: A variable length of data is set for
reception (TRCV).
DATA IN_OUT Variant Pointer to send (TSEND) or receive (TRCV) data area; data area
contains the address and length. The address refers to I memory,
Q memory, M memory, or a DB.TSEND:
 0: Job not yet started or still running.
 1: Job executed without error.
NDR OUT Bool TRCV:
 NDR = 0: Job not yet started or still running.
 NDR = 1: Job successfully completed.
BUSY OUT Bool  BUSY = 1: The job is not yet complete. A new job cannot be
triggered.
 BUSY = 0: Job is complete.
ERROR OUT Bool ERROR = 1: Error occurred during processing. STATUS provides
detailed information on the type of error
STATUS OUT Word Status information including error information. (Refer to the Error
and Status condition codes in the table below.)
RCVD_LEN OUT Int TRCV: Amount of data actually received in bytes
Note
The TSEND instruction requires a low-to-high transition at the REQ input parameter to start
a send job. The BUSY parameter is then set to 1 during processing. Completion of the send
job is indicated by either the DONE or ERROR parameters being set to 1 for one scan.
During this time, any low-to-high transition at the REQ input parameter is ignoredThe default setting of the LEN parameter (LEN = 0) uses the DATA parameter to
determine the length of the data being transmitted. Ensure that the DATA transmitted by
the TSEND instruction is the same size as the DATA parameter of the TRCV instruction.
As soon as all the job data has been received, TRCV transfers it to the receive area and sets
NDR to 1. 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. Immediately after receiving a block of data, TRCV enters the data in the receive
area and sets NDR to 1.
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".
Table 10- 14 ERROR and STATUS condition codes for TSEND and TRCV
ERROR STATUS Description
0 0000  Send job completed without error (TSEND)
 New data accepted: The current length of the received data is shown in RCVD_LEN
(TRCV).
0 7000  No job processing active (TSEND)
 Block not ready to receive (TRCV)
