A single point to modify a behavior of intelligent electronic devices (IEDs) between active and testing modes is disclosed herein. The IED may include a variety of logical nodes, each with a behavior object related to the active or testing mode behavior of the IED. A single testing mode selection point of the IED is used to modify each of the logical nodes to change between active and testing modes. The testing mode selection point may be a logical input. The testing mode selection point may be a physical switch on the IED.

Configuration of testing modes in substation devices

Pedestrian call systems with bidirectional communication between pedestrian call stations and traffic controllers are arranged so as to detect system errors. Communications can be provided over power conductors, and systems can be configured and monitored using a web browser. In one example, traffic systems are provided with Ethernet interfaces that can be used for bidirectional communication over power lines.
