In the "Trigger" parameter group you configure triggering for sending the message and other
parameters.
●
E-mail trigger / SMS trigger
Specifies the event for which the sending of the message is triggered:
– Use PLC tag
For the trigger signal to send the message, the edge change (0 → 1) of the trigger bit
"PLC tag for trigger" that is set by the user program is evaluated. When necessary, a
separate trigger bit can be configured for each e-mail. For information on the trigger
bit, see below.
– CPU changes to STOP
– CPU changes to RUN
– Connection to a partner interrupted
Triggers the sending of the message when the connection to a partner is interrupted.
– Connection to a partner established
Triggers the sending of the message when the connection returns.
– Weak mobile wireless network
Only with SMS
Triggers the sending of an SMS message when the network is weak and possibly no
dialup connection can be established via mobile wireless.
●
PLC tag for the message trigger "Use PLC tag"
If the memory area of the trigger bit is in the bit memory or in a data block, the trigger bit
is reset to zero when the message is sent.
●
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 (diagnostics
status) or read it out from the PLC tag.
For the significance of the status output in hexadecimal, refer to the section Processing
status of messages (Page 177).
