2-4 Using the Mail Send Function

2-4-1 Procedure

1.Make the basic settings.

For details, refer to Section 2 Installation and Initial Setup in the Operation Manual Con- struction of Networks.

↓

2.Connect the CX-Programmer online and make the following settings in the Unit Setup (CPU Bus Unit System Setup):

•SMTP Tab (required)

•POP Tab (when the Use POP before SMTP option is selected)

•DNS Tab (when using a host name)

•Mail Address Tab (Register one or two destination e-mail addresses.)

•Send Mail Tab (Register up to 8 send mail conditions and corresponding send data.)

↓

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.When the preset condition is established, an e-mail will be sent automatically to the specified destination address(es).

↓

5.The Send Mail Status (words m and m+17 of the allocated DM Area words) can be checked from the ladder program when necessary.

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 sent). Bit 01 of word n+17 in the allocated CIO Area words will be ON while the relevant memory is being accessed.

Note 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
