The job status is indicated at the output parameters BUSY and STATUS. STATUS
corresponds to the RET_VAL output parameter of asynchronously functioning instructions.
The following table shows the relationships between BUSY, DONE (TUSEND), NDR
(TURCV), and ERROR. Using this table, you can determine the current status of the
instruction (TUSEND or TURCV) or when the sending (transmission) / receiving process is
complete.

Due to the asynchronous function of the instructions: For TUSEND, you must keep the data in the sender area
1
consistent until the DONE parameter or the ERROR parameter assumes the value TRUE. For TURCV, the data in the
receiver area are only consistent when the NDR parameter assumes the value TRUE.

Description
Status parameter NDR (TURCV):
0: Job not yet started or still running.
•
1: Job has successfully completed.
•
1: Job is not yet completed. A new job cannot be triggered.
•
0: Job has completed.
•
Status parameters with the following values:
0: No error
•
1: Error occurred during processing. STATUS provides
•
detailed information on the type of error.
Status information including error information. (Refer to the Error
and Status condition codes in the table below.)
Number of bytes received (TURCV)
Address of the sender area (TUSEND) or receive area
(TURCV):
The process image input table
•
The process image output table
•
A memory bit
•
A data block
•
Pointer to the address of the receiver (for TUSEND) or sender
(for TURCV) (for example, P#DB100.DBX0.0 byte 8). The
pointer may point to any memory area.
A structure of 8 bytes is required as follows:
First 4 bytes contain the remote IP address.
•
Next 2 bytes specify the remote port number.
•
Last 2 bytes are reserved.
•
Description
The job is being processed.
The job was completed successfully.
The job was ended with an error. The cause of the error can be
found in the STATUS parameter.
The instruction was not assigned a (new) job.
