Subject name of the e-mail: STRING data with a maximum
length 240 characters.

ADDR_MAIL_SERVER = DW#16#C0A800C8, where:
192 = 16#C0,

168 =16#A8

0 = 16#00 and

The maximum time allowed for TM_MAIL to establish a
server connection. 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.

length 180 characters.
Mail server password: STRING data with a maximum length
