Examples Using Analog Transmission Path
CLE
Copper line equipment module
CSPi
Central signal processing unit
FO
Fiber-optic module
a)
4-wire Link
b)
2-wire Link
c)
Power line analog
d)
Power line via fiber optic
Examples 1 and 2:
Pilot cable connections
For operation via pilot cable, 2 SWT 3000 devices can be linked directly through the analog interfaces (CLE).
Example 3:
Power-line carrier connections
The analog interfaces (CLE) between 2 SWT 3000 devices can also be a PLC link. Depending on the device
configuration, SWT 3000 can be used with PowerLink in alternate multi-purpose, simultaneous multi-purpose,
or single purpose mode.
Example 4:
Fiber-optic connections between SWT 3000 and PowerLink
A short-distance connection between an SWT 3000 and Siemens PowerLink PLC terminal can be realized via an
integrated fiber-optic module. In this case, an SWT 3000 stand-alone system provides the same advanced
functionality as the version integrated into PowerLink. Each PowerLink can be connected to 2 SWT 3000
devices via fiber-optics.
