● Enable identifier for processing status
If the option is enabled, every attempt to send returns a status with information about the
processing status of the sent message.
The status is written to the "PLC tag for processing status". If there are problems
delivering messages, you can determine the status via the Web server of the CPU by
displaying the value of the PLC tag there.
For the significance of the status output in hexadecimal, refer to the section Processing
status of e-mails (Page 96).
● PLC tag for processing status
PLC tag of the type DWORD for the processing status
● Include value
If you enable the option, the CP sends a value for the placeholder $$ from the memory
area of the CPU in the message. To do this enter "$$" as a placeholder for the value to
be sent in the message text.
Select a PLC tag whose value will be integrated in the message. The value is entered in
the message text instead of the placeholder $$.
$$ can be a placeholder for data point types with a simple data type up to a size of 32
bits.
● PLC tag for value
