Abstract
The present invention concerns a procedure for modernizing the control system of a lift group, in which procedure the group control system coordinating the operation of the lifts is renovated and connected to the already existing lift-specific control system. As taught by the new procedure, for each lift is connected one matching computer between the new group control and the apparatus controlling the functions of the lift, and by the aid of which the lift-specific signals are transmitted to the control of the lift and to the group control.
