Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This blocks computes output y as sum of the three input signals u1, u2 and u3: 

y = k1*u1 + k2*u2 + k3*u3;

Example: 

   parameter:   k1= +2, k2= -3, k3=1;

results in the following equations:

   y = 2 * u1 - 3 * u2 + u3;
