DONE, BUSY and ERROR parameters
The output parameters DONE, BUSY and ERROR are each displayed for only one cycle if
the status of the BUSY output parameter changes from "1" to "0".
The following table shows the relationship between DONE, BUSY, and ERROR. Using this
table, you can determine the current status of the instruction "TMAIL_C and when the
sending of the e-mail is complete.

Explanation
Notes
0000 The processing of TMAIL_C was
completed without errors.
Error-free completion of TMAIL_C does not
mean that the e-mail sent will necessarily
arrive.
Incorrectly entering the recipient addresses
does not generate a status error of the
TMAIL_C instruction. In this case, there is no
guarantee that the e-mail will be sent to other
recipients, even if these were entered correct-
ly.
7001
TMAIL_C is active (BUSY = 1).
First call: Job triggered.
7002
TMAIL_C is active (BUSY = 1).
Intermediate call: Job already active.
8xxx The processing of TMAIL_C was
completed with an error code of the
communication instructions called
internally.
