Teleservice communication (SMTP email)
13.1 TM_Mail (Send email) instruction
Description
Subject name of the email: STRING data with a maximum
length 240 characters.
Text message of the email (optional): STRING data with a
maximum length of 240 characters.
If this parameter is an empty string, then the email will be
sent without message text.
Pointer to email attachment data: Byte, word, or double
word data with a maximum length of 65534 bytes.
If no value is assigned, then the email sent without an
attachment.
0 - Job not yet started or still executing.
•
1 - Job was executed error-free.
•
0 - No operation in progress
•
1- Operation in progress
•
The ERROR bit =1 for one scan, after the last request was
terminated with an error. The error code value at the
STATUS output is valid only during the single scan where
ERROR = 1.
Return value or error information of the TM_MAIL
instruction.
IP address of the mail server: You must assign each IP
address fragment as an octet of two 4-bit hexadecimal
characters. If the IP address fragment = decimal value 10
which equals hexadecimal value A, then you must enter
"0A" for that octet.
For example: IP address = 192.168.0.10
ADDR_MAIL_SERVER = DW#16#C0A8000A, where:
192 = 16#C0,
•
168 =16#A8
•
0 = 16#00
•
10 = 16#0A
•
The maximum time allowed for TM_MAIL to complete the
entire SMTP process, from the initiation of the conneciton to
the SMTP to the end of the SMTP transmission. If this time
is exceeded, then TM_MAIL execution ends with an error.
The actual time delay until TM_MAIL ends and the error is
issued may exceed the WATCH_DOG_TIME, because of
the additional time required for the disconnect operation.
At first you should set a time of 2 minutes. This time can be
much smaller for an ISDN phone connection.
Mail account user name: STRING data with a maximum
length 180 characters.
Mail server password: STRING data with a maximum length
180 characters.
