E-mails
The modules can generate and send e-mails due to events. The following recipients are
possible:
● PCs with an Internet connection
● Cell phones
● SIMATIC stations with the appropriate program blocks
Inter-station communication
Direct inter-station communication between S7 stations with a TIM is possible via IP-based
networks.
Inter-station communication, in contrast, runs via a master station that forwards the frames to
the target subscriber.
