Abstract
In networked electronic ordnance systems as disclosed herein, a plurality of pyrotechnic devices communicate with a controller along a common bus. In accordance with an embodiment of the disclosure, at least some of the pyrotechnic devices in the ordnance system are configured such that the address for those devices can be defined during or subsequent to installation of the pyrotechnic devices in an end system. In some instances, a logic device in the pyrotechnic device includes a diagnostics block that initiates a suite of diagnostic tests within the pyrotechnic device in response to a diagnostics command received by the pyrotechnic device. Additionally, in some instances, an additional safety mechanism is added to an energy-reserve capacitor in the pyrotechnic device in compliance with a safe-by-wire standard.
