Elevator installation having a central control in a remote central operation center

A method for controlling operation of an elevator installation system including at least one elevator installation which has at least one elevator, control means for controlling operation of the elevator installation, a service center which is spatially separate from the elevator installation for monitoring operation of the installation, the control means being located at the service center so that no elevator controls are at the elevator installation, and data transmission means for exchanging data relevant to an elevator between the elevator installation and the service center, the data transmission means including a first transmission device arranged in the service center, and a second transmission device arranged at the elevator installation, and a data path arranged to connect the first transmission device to the second transmission device, the method comprising the steps of:

• transmitting data relevant to control of the elevators, via the data transmission means, to the control means which is spatially separate from the elevators;
• processing the transmitted data in the control means into control commands for the elevators;
• and
• transmitting the control commands from the service center by way of the data transmission means to the elevators for actuating setting members.
