Chapter 4 PAS Application Software General Meter Setup To configure the Analog Inputs in your device, select General Setup from the Meter Setup menu, and click on the Analog Inputs tab. If you are programming your device online, analog inputs are designated as not available if they are not present in the device. The available options are described in the following table.
Chapter 4 PAS Application General Meter Setup zero. The device does not allow you to access this setting. Whenever the direction of the input current is changed to negative, the device automatically uses your full engineering scale settings for +1 mA with a negative sign. Scaling Analog Inputs for 0-2 mA and ±2 mA The input scales for 0-1 mA and ±1 mA analog inputs are always programmed for 0 mA and +1 mA regardless of the desired input range.
Chapter 4 PAS Application Software General Meter Setup When you select an output parameter for the analog output channel, the default engineering scales are set automatically. They represent the maximum available scales. If the parameter actually covers a lower range, you can change the scales to provide a better resolution on the analog outputs.

Chapter 4 PAS Application Software General Meter Setup examples of pulsed events are pulse inputs (transition pulses on the digital inputs), internal pulsed events (energy pulses and time interval pulses), and events generated by the interval timers. The logical controller automatically clears pulsed events at the end of each scan, so that triggers that used pulsed events are prevented from being triggered by the same event once again.
Chapter 4 PAS Application General Meter Setup Using Setpoint Events and Actions When a setpoint status changes, i.e., a setpoint event is either asserted or de-asserted, the following happens in your device: 1. 2. 3. The new setpoint status is logged to the setpoint status register that can be monitored through communications from the SCADA system or from a programmable controller in order to give an indication on the expected event.

To view or change the factory-set DNP Class 0 assignments, select Protocol Setup from the Meter Setup menu and click on the DNP Class 0 Points tab.
Chapter 4 PAS Application Software Configuring Communication Protocols A change event point index is normally the same as for the corresponding static object point. If you wish to use independent numeration for event points, enable re-mapping event point indices via DNP Options setup (see above) so they would start with index 0. You should define a separate event setpoint for each static object point you wish to be monitored for change events.
