Sending e-mails
To transfer encrypted e-mails with this block, the precise time of day is required on the
module. Configure the time-of-day synchronization.
To change the configuration data of the module during runtime:
●
Program-controlled configuration of the IP parameters
Refer to the information on T_CONFIG and on the SDTs "IF_CONF_..." in the section
Changing the IP address during runtime (Page 159).
You can find the program blocks in STEP 7 in the "Instructions > Communication > Open
User Communication" task card.
Connection descriptions in system data types (SDTs)
The blocks listed above use the CONNECT parameter for the relevant connection
description. TMAIL_C uses the parameter MAIL_ADDR_PARAM.
The connection description is stored in a data block whose structure is specified by the
system data type (SDT).
Creating an SDT for the data blocks
Create the SDT required for every connection description as a data block (global DB).
The SDT type is generated by entering the name in the declaration table of the block
manually not by selecting an entry from the "Data type" drop-down list but by entering it in
the "Data type" box for example "TCON_IP_V4".
The corresponding SDT is then created with its parameters.
