With an MIQ/PS power supply module (18 W), there is still an
energy reserve of 10.2 W for any future extensions.
3.2.3 Topology and terminator switch
For failure-free operation, the terminator switches (terminating resis-
tors) must always be set to ON on two MIQ modules of the
IQ S
ENSOR N ET island. On which modules this is required results from
the topology of the IQ S ENSOR N ET island:
Fig. 3-1 Correct setting of the terminator switches
Main line (trunk
line) Longest cable section with terminator switches at
its ends.
The terminator switches must be set to On at both
ends.
If all MIQ modules are located at one point, i. e. in
a module stack, the length of the main line is zero
(star-shaped wiring).
Branch line All lines branching from the main line.
Branch lines can be branched further.
