.Buildings.Controls.OBC.CDL.Reals.MultiSum

Information

Block that outputs

y = ∑_i=1ⁿ k_i   u_i,

where k is a parameter with n elements and u is an input of the same length. The dimension of u can be enlarged by drawing an additional connection line. The connection is automatically connected to this new free index.

If no connection to the input connector u is present, the output is y=0.

See Buildings.Controls.OBC.CDL.Reals.Validation.MultiSum for an example.
