LOCKOUT/TAGOUT DEVICE WITH NON-VOLATILE MEMORY AND RELATED SYSTEM

摘要

A lockout/tagout or smart isolation device includes a wireless link, a non-volatile memory, and a controller in communication with the wireless link and the non-volatile memory. The wireless link is in selective communication with a wireless identification device, such as a keycard, carried by a user. The controller is programmed to receive a signal from the wireless link and write usage information about the device to at least a portion of the non-volatile memory such that the portion of the non-volatile memory storing the usage information cannot be erased or re-written thereby securely storing this usage information. This lockout/tagout or smart isolation device may be standalone or be part of a system that may potentially serve as part of a facility-wide safety system (for example, networked or in communication with a SCADA system).
