Abstract
A method of checking the functional capability of at least one safety element of a safety circuit of an elevator installation utilizes a first processing unit and a second processing unit for the at least one safety element. The at least one safety element is connected with a control unit by a communications network. At least one signal is provided by the first processing unit on the basis of at least one communication from the control unit. The at least one provided signal is detected by the second processing unit connected with the first processing unit and is communicated to the control unit by way of the communications network. The at least one communicated signal is checked for the validity thereof by the control unit.
