10 USING THE E-MAIL FUNCTION
POINT
(1) The Ethernet module checks whether there is incoming mail in the mail server
at the time interval set in the Mail parameter (BFM#9904).
If there is incoming mail, the reception information is stored in the following
areas of the buffer memory.
• The number of received mail on the mail server is stored in the received mail
count storage area (BFM#22640).
(2) When there is mail stored on the mail server, execute the FROM/TO instruction
to receive them.
Received mail accumulate on the mail server if the mail is not received.
(3) E-mails that have been read from the mail server are deleted.
(4) If the Ethernet module has received e-mail longer than 2k words, it stores the
data equivalent to the reception data length and ignores the remaining data.
