1.1.5 Versatile Communication, Integrated Node Functionality
There are several possible means of communicating with the control center:
• Multi-point communications
You can connect external communications modules via the RS-232 or via the RS-485 in-
terface for transmission in joint traffic. The standard protocols are freely selectable
(IEC 80870-5-101, DNP 3.0, Modbus RTU). Additional protocols are available on request.
• Dial-up traffic
Various connection-oriented transmission media are supported as standard via dial-up
traffic (PSTN, ISDN, GSM, TETRA).
• LAN/WAN
In the case of communication via LAN/WAN networks, transmission is implemented in ac-
cordance with the standards IEC 60870-5-104 or IEC 61850 or DNP(i) – based on Ether-
net TCP/IP.
Further local devices can be connected in a very simple way via the further communication in-
terfaces, in order to connect them to an entire unit.
