Configuring SMS messages
If important events occur, the CP can send SMS messages. The recipient can be a mobile
phone or an S7-1200.
You configure the SMS message in STEP 7 in the data point and message configuration.
You can find this using the project tree:
Project > directory of the relevant station > Local modules > CP
For the view in STEP 7, refer to the section Configuring data points and messages
(Page 47).
You will find the character set supported for the text of the SMS message in the section
Programming SMS messages via OUC (Page 93).
If important events occur, the CP can send e-mails. The recipient can be a PC with an
Internet connection or an S7-1200.
You configure the e-mails in STEP 7 in the data point and message configuration. You can
find this using the project tree:
Project > directory of the relevant station > Local modules > CP

Triggering sending of messages
One of the following events triggers sending of the message:
● CPU changes to STOP.
● CPU changes to RUN.
● The connection to the partner is interrupted.
● The connection to the partner is re-established.
● Connection establishment has failed.
● Weak mobile wireless network (signal quality)
● A trigger signal is fired.
For the trigger signal to send the message, the edge change (0 → 1) of a trigger bit is
evaluated that is set by the user program. When necessary, a separate trigger bit can be
configured for each message.
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.
