10.16.1.2 EASY-COM-SWD-… easy communication module
EASY-COM-SWD-…, with its connection to the easyE4 base device, acts as the
SmartWire-DT coordinator on the SmartWire-DT line.
EASY-COM-SWD-… combines the functionality of an easyE4 with direct connection
to SmartWire-DT communication system.
The easy communication module is where the SmartWire-DT line starts and has a
connection to the 8-pin SmartWire-DT ribbon cable used inside the control panel in
order to connect the SmartWire-DT modules. In addition to communication and con-
trol wires, this SmartWire-DT ribbon cable also carries the supply voltages for con-
nected SmartWire-DT modules (15V
DC
) and optionally used switchgear (24V
DC
).
These two supply voltages are supplied through the EASY-COM-SWD-… module via
the POW and AUX connection terminals.
