Memory sharing techniques include providing a first device and one or more additional devices. Each device has a memory and is configured to be connected to a network. A portion of the first device memory is allocated, and may be divided into two or more first device memory segments. Each first device memory segment corresponds to a device, and at least one of the first device memory segments corresponds to an additional device. A portion of the additional device memory is allocated, and may be divided into two or more additional device memory segments. Each additional device memory segment corresponds to a device, and at least one additional device memory segment corresponds to the first device. A first device data segment is provided to the additional device, and a first device data validity indication is derived at the additional device. The first device data validity indication is associated with the first device data segment, and the additional device memory segment corresponding to the first device is updated based on the association.

Distributed fault resilient shared memory

A data switch for transferring data from either actual line readings or from stored memory to the input of a relay tester. The device uses a digital switch set between the A/D converter and the CPU of an electronic relay. The switch permits technicians and engineers to either pass data to the CPU from the system through the A/D converter or, by switching, feed the CPU data from the RAM, which has been loaded with the archived data. In this way, the relay system software can be examined and tested using actual event data under ordinary conditions as desired, with relay settings changed between tests to verify the efficacy of the changed settings to perform as desired for the recorded conditions. The digital switch can be either a hard-wired element, or can be a soft switch, operated through software instructions.
