Congratulations on installing your new Senva EMX energy meter! This Modbus Protocol Guide assumes the first stage of installation is complete, with the meter and any CTs connected and powered. The OLEO display should show the home screen when any button is pressed. If not, refer to the separate Installation Instructions before continuing. Now, only the network configuration remains between you and the data.
From any screen, press the ENTER button to access the settings menu.

You can make selections using the UP and DOWN arrows and the pressing ENTER to proceed to that menu or setting.
From any menu, press the ESC button to go back one menu.

To change a value, use the UP and DOWN arrows to set each digit and the ENTER button to move the cursor left.

Once each digit has been set, hit ENTER a final time to return to the previous menu. To abandon changes at any time, you may hit ESC.

Setup Registers and Parameters

Setup registers and parameters are available in 6 groups in the settings menu using the display or they may also be accessed using BACnet communications.

Settings
Settings are available in the following groups on the display. A parameter list is provided in the following sections.

Metering – Adjust metering parameters such as voltage and current scaling, phase sequencing, and display units.
Pulse Output – Adjust the units, duration, and source of the two pulse outputs.
Communications – Set communications parameters such as protocol, baud rate, parity, and addressing.
Alarms – Enable or disable alarms and set trip points.
Passcode – Choose a passcode to lock device.
Advanced – View firmware versions or initiate a factory reset.

R/W:
R = Readable Only
R/W = Read and writeable

Scale:
Values must be multiplied by this scale factor to be read correctly. 15 * 0.1 = 1.5. When writing the value should be divided by the scale before being written. 1.5 / 0.1 = 15.

Logging Registers

EMX Logging:

Logging on the EMX is only available on models with firmware 2.0 or greater.
Log Source 1 – Log source 12 set the source for the logging. Write the Modbus register 1- 188 to the desired source to log that point. If a Modbus register has multiple register all registers need to be set. For example, if Real Net Energy total is desired to be logged all four registers need to be set.
To trigger a log event Logging – Trigger Source needs to be set to the desired trigger mode, by default it is set to be disabled. Logging can be triggered with the timer, set on Modbuspoint 5001 in seconds from 15-3600. Triggering can be set over COMMS by writing point 5015 a 1, or Pulse In 1 or 2 can be set to trigger a log whenever a pulse isa detected.
