Errors may occur in a detonating system that consists of several detonating circuits when the connection-the logging-on-of detonators is effected to the buses of a logger which in turn is connected to a blaster. Connecting is effected, particularly in opencast-mining operations, under conditions that may lead to damage, not visible at first, in particular to the insulation of the detonators and also of the detonating lines. Errors may occur in the transmission of data, for example as a result of loss or falsification of the signals to be transmitted or as a result of intrusion of signals from an extraneous detonator. In accordance with the invention it is therefore proposed that a log-on manager is installed which is in bidirectional contact with the loggers, with the blaster and with the log-data communicators of the loggers which signal the data pertaining to the detonators to the logger. The log-on manager coordinates the logging of the detonators on to the respective bus as well as the programming of the detonators and checks whether an error-free transmission of data is taking place.
