Each setpoint evaluates a logical expression with up to four arguments using OR/AND logic. Whenever an expression is evaluated as “true”, the setpoint performs up to four concurrent actions that can send a command to the output relays, increment or decrement a counter, or trigger a recorder.

- Page 96 Chapter 4 PAS Application Software Configuring Communication Protocols If the scaling unit is greater than 1, the counter value is reported being divided by the selected scaling unit from 10 to 1000. To get the actual value, multiply the counter reading by the scaling unit. Configuring DNP Class 0 The most common method of getting static object information from the meter via DNP is to issue a read Class 0 request.

Chapter 4 PAS Application Software Administration To reset the desired accumulation registers or to clear a file: Click on the corresponding button, and then confirm your command. If a target has more than one component, you are allowed to select components to reset. - Page 103 Chapter 4 PAS Application Software Upgrading Device Firmware Upgrading firmware is only supported through the Modbus RTU and Modbus/TCP protocols, so your serial port or modem port should be put into Modbus RTU mode. If you are upgrading firmware through the Ethernet port and your device has a firmware build lower than 7, the device Ethernet port should also be configured to operate through the Modbus/TCP port 502.
- Page 104 Chapter 4 PAS Application Software Upgrading Device Firmware Wait until PAS completes upgrading your device. It takes about 3-4 minutes at 115,200 bps to download the file to the meter. After upgrading firmware is completed, the meter restarts, so if it is connected through the modem to your PC, communications can be temporarily lost.
