90 Network Guide
If you connect a second expansion module of the same type to the controller's subnetwork
data bus, you must set at least one of the two expansion modules' MAC DIP switch to a
unique (that is, unused) subnet ID (MAC) address and then set the same value in Default
address in EC-
gfx Program. See "Manage Light and Sunblind Module Instances" in the EC-
gfx Program User Guide.

In EC- gfx Program, when the connection status for the controller is Connected, this scans the
controller's subnetwork data bus for connected expansion modules, when each expansion
module has a unique subnet ID (MAC) address on the controller's subnetwork data bus. Using
this feature will delete any previously configured expansion modules. See "Manage Light and
Sunblind Module Instances" in the EC-
gfx Program User Guide.
