Procedure

Note
38
1. Mount the Ethernet Unit in the CPU Rack or Expansion Rack, connect online with the
CX-Programmer or Programming Console, and create the I/O table.
2. With the CX-Programmer still connected online, make the following settings in the Unit
Setup (CPU Bus Unit System Setup):
• SMTP Tab (required)
• POP Tab (required)
• DNS Tab (when using a host name)
• Receive Mail Tab (when using protection settings to specify the source e-mail address,
allowed commands, and allowed attached files)
3. Select Transfer to PLC from the Options Menu and click the Yes Button to transfer the
Unit Setup (CPU Bus Unit System Setup) to the CPU Unit. (The settings data will be
transferred to the CPU Bus Unit System Setup Area.)
4. Create e-mail containing the remote mail command to send to the Ethernet Unit.
1. For the destination address, enter the Ethernet's local mail address set in the CPU Bus
Unit System Setup.
2. Enter the command name as the e-mail subject.
3. Enter the parameters in the e-mail body.
4. If the command uses an attached file, attach the file.
Note To preserve the simultaneity of the data when a data file is being sent as an
attachment, add a condition to write processes in the ladder program so that the
region of memory being converted to a data file is not overwritten from the ladder
program while memory is being accessed (mail is being received). Bit 02 of word
n+17 in the allocated CIO Area words will be ON while the memory is being
accessed.
5. Send the created e-mail to the Ethernet Unit.
6. A response e-mail will be returned automatically.
The Ethernet Unit will be restarted when the settings data is transferred to the
CPU Bus Unit System Setup Area, so that the new settings are read and
become effective. Verify that it is safe for the Ethernet Unit to restart before
transferring the settings data.
