Wilo Net is a bus system which enables up to 21 Wilo products (participants) to com-
municate with one another. The Wilo-Smart Gateway is one of these participants.
Application for:
ƒ
twin-head pumps consisting of two participants
ƒ
Multi-Flow Adaptation (feeder pump connected to secondary pumps)
ƒ
remote access via Wilo-Smart Gateway
Bus topology
The bus topology consists of multiple participants (pumps and Wilo-Smart Gateway),
which are switched on in sequence. The participants are connected via a shared cable.
The bus must be terminated at both ends of the cable. This is done for the two external
pumps in the pump menu. All other subscribers should not have activated termination.
All bus subscribers must be assigned an individual address (Wilo Net ID).
This address is set in the pump menu of the respective pump.
To terminate the pumps:
In the "Settings" menu , select
1. "External interfaces"
2. "Wilo Net setting"
3. "Wilo Net termination".
Possible selection:
Wilo Net termination
Switched on
Switched off
After termination is done, an individual Wilo Net address is assigned to the pumps.
Description
Terminating resistor of the pump is
switched on.
If the pump is connected at the end of the
electrical bus line, "Switched on" must be
selected.
The pump's terminating resistor is
switched off.
If the pump is NOT connected at the end
of the electrical bus line, "Switched off"
must be selected.
