7. Examples of connection
• iSolar WMZ:
master board
subaddress: “0“
bus mode: “active“
7.1 iSolar WMZ module in individual
operation mode
7.2 iSolar WMZ with controller
• controller:
register iSolar WMZ module
• iSolar WMZ:
slave board
subaddress: “0“
bus mode: “passive“
7.3 Cascade without controller
• iSolar WMZ 0:
master board
subaddress “0“
bus mode: “Cascaded“
bus master: “Yes“
• iSolar WMZ 1 ... 15: slave board
subaddress: 1 ... 15*
bus mode: “Cascaded“
The connection sequence at the VBus
®
is arbitrary.
7.4 Cascade with controller
• controller:
No adjustments have to be made
(
iSolar
WMZ-module must not be
registered!)
• iSolar WMZ 0:
slave board
subaddress: “0“
bus mode: “cascaded“
bus master: “No“
• iSolar WMZ 1 ... 15: Slave board
subaddress: 1 ... 15*
bus mode: “Cascaded“
The connection sequence at the VBus
®
is arbitrary.
* The maximum number of cascaded iSolar WMZ modules
is 16. Whether this number can be reached depends on the
construction.
Disturbing factors can be the following: distances, voltage-
carrying lines etc.
iSolar WMZ 0
