Return value STATUS (W#16#...): | Return value SFC_STATUS (W#16#...): | Explanation | Notes |
|---|---|---|---|
0000 | - | The processing of "TM_MAIL" was completed without errors. | A error-free completion of "TM_MAIL" does not mean that the sent e-mail will necessarily arrive (see below - note on point 1) |
7001 | "TM_MAIL" is active (BUSY=1). | Initial call; job has started | |
7002 | 7002 | "TM_MAIL" is active (BUSY=1). | Intermediate call; job already active |
8xxx | xxxx | The processing of "TM_MAIL" was completed with an error code of the internally called communication instructions. | For detailed information on the evaluation of the SFC_STATUS parameter, refer to the descriptions of the STATUS parameter of the communication instructions. |
8010 | xxxx | Error during connection establishment. | For further information on the evaluation of the SFC_STATUS parameter, refer to the descriptions of the STATUS parameter of the "TCON" instruction. |
8011 | xxxx | Error sending the data. | For detailed information on the evaluation of SFC_STATUS, refer to the descriptions of the STATUS parameter of the "TSEND" instruction. |
8012 | xxxx | Error receiving the data. | For more information on the evaluation of SFC_STATUS, refer to the descriptions of the STATUS parameter of the "TRCV" instruction. |
8013 | xxxx | Error during connection establishment. | For more information on the evaluation of SFC_STATUS, refer to the descriptions of the STATUS parameter of the "TCON" and "TDISCON" instructions. |
8014 | - | Establishment of a connection is not possible. | You have possibly entered an incorrect mail server IP address (ADDR_MAIL_SERVER) or a time span that is too short (WATCH_DOG_TIME) to establish the connection. It is also possible that the CPU has no connection to the network or that the CPU configuration is incorrect. |
82xx, 84xx, or 85xx | - | The error message originates from the mail server and corresponds, except for the "8", to the error number of the SMTP protocol. The following columns list several error codes that can occur: | See point 2 in the note. |
8450 | - | Action not executed: Mailbox not available/not reachable. | Try again later. |
8451 | - | Action aborted: Local processing error | Try again later. |
8500 | - | Syntax error: Error not recognized. This also includes the error when a command string is too long. This can also be occur when the e-mail server does not support the LOGIN authentication procedure. | Check the parameters of "TM_MAIL". Try to send an e-mail without authentication. To do this, replace the USERNAME parameter with an empty string. |
8501 | - | Syntax error: Parameter or argument incorrect | You have possibly entered an incorrect address in TO_S or CC. |
8502 | - | Command unknown or not implemented. | Check your entries, in particular the FROM parameter. This is possibly incomplete and you have forgotten "@" or ".". |

8550 | - | Mail server cannot be reached, you have no access rights. | You have possibly entered an incorrect user name or password, or the mail server does not support your LOGIN. Another cause of error could be an incorrect entry of the domain name after the "@" in TO_S or CC. |
8552 | - | Action aborted: Assigned memory size has been exceeded | Try again later. |
8554 | - | Transmission failed. | Try again later. |
