In this context the reliability should be understood as an improvement in the capacity of all system to guarantee that the remote power switch works as expected, or under failure it will trip to a well-defined state. \n\n\nTo accomplish this behaviour the system implements: \n* A Watch-Dog supervisor code. \n* A current feedback signal (using a non-invasive current transformer). \n\n\nThe two systems work independently to guarantee the system whole reliability. The Watch-Dog code is a simple register counter that increments by one with each state-machine cycle. The Watch-Dog counter is reset with each successful operation and put the system in a \"turn-off\" state when the counter reaches a threshold level. \n\n\nThe current transformer measures the real current that feeds the power load. This signal allows to the control system to know if the load is really working or not and then take the right action. The last versions of NearBus system offers enhanced features like the True RMS function that allows know the true RMS current value of the load. This feature allows calculate the active power that the load is consuming. \n\n\n\n'''Current Feedback'''\n\nTo know if the Motor is running the system measured the current through the \"RMS_INPUT\" service. Before to measure the current, the system configures the remote ADC to a value of 1100mV calling the \"RMS_INPUT_CONFIG\" service (because this example uses a low power motor of only 15 Watts). The measured current is compared with a threshold reference of 10 in order to decide if the Motor is running or not. \n\n\n\n'''Power Calculation'''\n\nIn order to calculate the active Power consumption we use the following parameters: \n\n * V = 220Vac\n * Power Factor = 0.75 (inductive motor)\n * TI Ratio = 5:2 [A/V]\n * Vref ADC 1100mV\n * ADC resolution 10 bits (1023)\n \n '''Power [Watts] = Irms * (1100 / 1023) / 1000 * (5 / 2) * 220 * 0.75'''\n\n\n\nThe following picture shows the prototype used to test this example.\n\n[[File:Motor_switch_01.png|600px]]
