Permissible topology for the C-NET
The C-NET can be wired in the topology shown below. Regardless of the topology
(loop, stub or loop with sub-stub), the C-NET system limits, such as length, cable
resistor, number of users etc., must be observed.
Either one loop or two stubs can be connected to the C-NET detector line of the
FC721 (2-wire line to block of 4 terminals).
Loop
(max. 1 loop)
Stub

Sub-stubs on loop
A sub-stub must only be connected between two line devices or line
separators as well as directly to the terminal connection.
