Wiring assignment
An 8-core connecting cable is used by SWD coordinator to feed the SWD
modules with power and exchange data. SmartWire-DT is self-configuring
and addresses its modules at the push of a button.
Table 6:
Configuration of the SmartWire-DT ribbon cable
The power supply for SWD coordinator and the SWD modules is connected
via the POW terminals. The 15 V power supply of the SWD modules U
SWD
is
generated from POW.
If you wish to use contactors, circuit-breakers or motor starters in the instal-
lation with SmartWire-DT, a 24 V DC voltage U
AUX
must be fed in at AUX.
Definition of terms: components - elements - modules
The SWD components consist of SWD modules and SWD elements.
SWD modules are all those SWD components that respond to a request
from the SWD coordinator, i.e. can exchange data. They are assigned an
SWD module address.
SWD elements are passive SWD components that do not exchange data but
are required for operating the SmartWire-DT network. SWD elements are,
for example, the power feeder modules, SWD cables, adapters etc. SWD
elements are not given an SWD module address.
SWD universal module
If functions have to be retrofitted on an installation, modifications in the hard-
ware configuration and program extension are normally very labor-intensive.
The use of a universal module enables you to initially replace the SWD mod-
ules that are required at a later time. If the installation is then extended later,
the planned modules are then installed instead of the universal modules. In
this way, you will be able to retain all module addresses.A detailed descrip-
tion on connecting the universal modules is provided in the "SmartWire-DT
Modules", MN05006001Z-EN.
