5.4.1 Network connection and disconnection methods and their combinations

5 - 15
This section explains the network connection and disconnection methods and their
combinations and the procedures for connecting to and disconnecting from the
network with sequence programs.
This section provides the network connection and disconnection methods and their
combinations.
(1) Network connection methods
The following indicates how the Web server module connects to the network.
(a) Automatic connection at start-up
When "Automatic connection to network at start-up." is set in the system
setting, the Web server module automatically connects to the network at a
start. (Refer to Section 4.6.3.)
(b) Connection using sequence program
When Network connection request (Y5) turns from OFF to ON in a
sequence program, the Web server module connects to the network. (Refer
to Section 5.4.2.)
(c) Automatic connection at execution of dedicated instruction (WMSEND,
FTPPUT, FTPGET)
When the dedicated instruction is executed, the Web server module
automatically connects to the network. (Refer to Chapter 8.)
(d) Automatic connection at e-mail transmission or file transfer by logging
function
When e-mail transmission or file transfer is performed, the Web server
module automatically connects to the network. (Refer to Section 6.4.)
(e) Automatic connection at e-mail transmission by event function
When e-mail transmission is performed, the Web server module
automatically connects to the network. (Refer to Section 6.5.)
(f) Connection by Call function (Only when modem is connected)
When the "Call function" is enabled in the dial-up setting, making a phone
call from a telephone to the Web server module side modem connects the
Web server module to the network. (Refer to Section 4.6.4.)
(2) Network disconnection methods
The following indicates how the Web server module disconnects from the
network.
(a) Disconnection using sequence program
When Network disconnection request (Y7) turns from OFF to ON in a
sequence program, the Web server module disconnects from the network.
(Refer to Section 5.4.2.)
