2.2 Communications services
The following communications services are supported:
Telecontrol communication
Network types
The TIM makes telecontrol communication possible via the following network types:
● Industrial Ethernet
● Dedicated line / wireless network
● Analog dial-up network, ISDN network
● Mobile networks (with the aid of a SCALANCE M router)
– GSM / GPRS (2G)
– UMTS (3G) / HSPA+
– LTE (4G)
● IP-based wireless networks
You will find an overview of the transmission paths and network types in the section
