●
Independent of media
The LINK supports the connection of bus adapter modules of the ET 200SP device
family, for example for connecting to optical networks.
●
Redundant power supply
The LINK can be connected to a redundant power supply.

Characteristics of S7 communication
Table 1- 1
Number of connections for S7 communication
Characteristic
Explanation / values
Maximum number of S7 connections / HMI con-
nections
32
For the S7 communication both configured and unconfigured S7
connections are used.
1.3.2
Characteristics of data record routing
Field device parameter assignment (data record routing)
You can use the LINK as a router for data records intended for field devices (PROFIBUS
nodes):
Devices that are not connected directly to PROFIBUS and therefore have no direct access to
the field devices can send data records to the field devices for example via the LINK using
the SIMATIC PDM (Process Device Manager).
The function is enabled as default.
Characteristic
