Abstract: A modular electric power distribution system transmits power between a power source and control modules for power consumers. The system includes a power distribution unit mounted on each module and bridge assemblies which connect adjacent distribution units.

Abstract: A modular electric power distribution system distributes electric power between a power source and control modules for power consumers or other electronic components.

Abstract: A network diagnostic module coupleable to a distributed process control network that controls an industrial process via field devices coupled to the network includes a power block coupleable to the network and configured to power the network diagnostic module with energy received from the network, a communications block coupleable to the network and configured to bi-directionally communicate over the network, and a diagnostics block coupleable to the network and configured to make diagnostic measurements of network and protocol parameters of the network. The network diagnostic module is not itself a field device that detects or controls any process variable of the industrial process, enabling the network diagnostic module to be placed essentially anywhere along the network to permanently monitor the network.
