Abstract
In a data communication system, data is transmitted from a control device to a communication interface and from there via a communication bus to additional communication interfaces of trigger devices. The communication interface on the control device side has inputs, to which signals from said control device and a disarming switch can be assigned. The disarming switch can be circumvented by a bypass switch which is controlled by the control device. The state of the signal at the inputs of the communication interface on the control device side is transmitted to coresponding outputs of the communication interfaces of the triggger devices. A trigger device has a safety unit which is used to test at least one trigger unit, when the state of the signal of the outputs authorizes such a test and the trigger voltage source is not yet charged wth the full trigger voltage. In said state, the safety unit also blocks triggering as soon as the trigger voltage has been reached. The inventive system ensures a high degree of functional safety and flexibility.
