AXM-WEB2 for Acuvim II Series Power Meter
Chapter 1: Introduction to Ethernet
The AXM-WEB2 module provides a dual Ethernet and WiFi communication channel for Acuvim II
series power meters. Users will be able to use both Ethernet ports and WiFi simultaneously with
dierent networks and data acquisition systems.
This communications module provides users with an industry leading 100ms and 40ms response rate via Modbus TCP that allows users to attain real time updates to key parameters
such as voltage, current and power from the Acuvim II Series meter.
1.1 Introduction to Ethernet
Ethernet was originally developed by Xerox and then further developed by DEC and Intel. This
networking technology uses Carrier Sense Multiple Access with Collision Detection (CDSM/CD)
protocol and provides transmission speeds up to 100Mbps.
Ethernet is a not a network but more of a standard. It is the most current communication stan-
dard Local Area Network(LAN). This standard denes the type of cable that is used and the
method of Signal Processing. The AXM-WEB2 module supports two Ethernet channels.
1.1.1 IPv6
The AXM-WEB2 module also supports IPv6 which is the latest version for the internet protocol.
The protocol uses 128-bit addressing in comparison to IPv4 which uses 32-bit addressing. The
dierence for addressing allows for more devices to be connected using IPv6 as opposed to the
IPv4 protocol. The protocol is more ecient and provides more secure routing over the inter-
net.
Chapter 2: Functional Description of the Ethernet module
The AXM-WEB2 module supports a wide range of communication protocols. Some of the more
commonly used protocols are briey explained below.
This module supports the Modbus-TCP protocol. When connected to the Acuvim II series meter,
it is a slave device that can only respond to queries. The default value for the Modbus Port is
502. The user dened range is 2000~5999.
The AXM-WEB2 grants users the ability to send emails based on a time interval or when there is
a triggered event using the SMPT protocol. It can send mail from encrypted servers and servers
that use dierent SMTP ports.
The AXM-WEB2 protocol supports HTTPS protocol. It is used as an HTTPS server and where the
default value of the protocol port is 443. Using the HTTPS protocol, the AXM-WEB2 can send
post requests to both HTTP and HTTPS servers.

6.4 Description of Modbus-TCP Protocol
The Modbus-TCP protocol is used as one of the communication protocols in
the AXM-WEB2. The protocol establishes a master and slave connection in
Ethernet. The master device(client) rst sets up a TCP-IP link with slave device(server). The master device then sends a request to the slave device and
the slave device in return sends a response to the master device. Figure below
shows how the Modbus-TCP protocol works.

d. Data Field
The data eld is constructed using sets of two hexadecimal digits, in the range of 00 to FF. The
data eld of messages sent from a master to slave contains additional information which the
slave must use to take the action dened by the function code. This can include information
such as the register addresses, the quantity of registers to query and the count of the actual
number of data bytes. For example, if the master requests a slave to read a group of holding reg-
isters(function code 03), the data eld species the starting register and how many registers are
to be read.
If the master needs to write data(function code 10 hexadecimal) to a group of registers in the
slave, the data eld species the starting register, how many registers to write, the count of data
bytes to follow in the data eld and the data to be written into the registers.

Demand Settings
Sliding Window:
This setting refers to the demand type. There are 4 demand types that are
supported by the Acuvim II series meter, users can choose one of the following:
1. Fixed Window
- The demand is calculated based on selecting the calculation period between 1-30min. The meter will calculate and update the demand values at the end of each
calculation period.
2. Sliding Window
- The demand is calculated by selecting the calculation period between
1-30 min. The meter will average the energy accumulated within this period of time and
the demand value is updated every minute.
3. Thermal
- The demand is calculated based on thermal response, used in thermal demand
meters. This method uses a sliding window to update the demand value at the end of each
calculation period.
4. Rolling Window
- The demand is based on selecting a calculation period between 1-30min,
a subinterval(Demand Calculation Slip Time) and the demand value is updated at each
subinterval. The subinterval must be a factor of the calculation period. For example, with a
calculation period of 15min, the subinterval can be congured as 5min.
Sub Interval:
The sub interval setting is only relevant if the Rolling Window Method is selected, this method requires a sub-interval time that must be a factor of the demand calculation
period. the range for this setting is from 1-30 minutes.

Backlight:
This setting refers to how long back light on the meters display is on for, the
range is from 0-120 minutes, where 0 would disable to back light from turning o .
Rated Load:
The rated load can be represented in terms of either power or current.
• If current is selected the rated current that is used would be the CT1 setting value in the
PT and CT ratio settings section of the web page. For example if CT1 is set for 1000A,
and the average current the meter is monitoring is 500A, the load percentage would be
50% (500/1000A).
• If power is selected the rated primary power would be used in the load percentage cal-
culation. The max primary power can be calculated as follows:
Max Primary Power without using PTs = 3 * (480) * (CT1)
Max Primary Power using PTs = 3 * (PT1) * (CT1)
The max primary power would be the power that is entered in this setting.
The load percentage is displayed on the front of the Acuvim II meter display. The load
percentage is calculated based on the following equation:
Load Percentage = (Active System Power / ((5A or 1A) * User Setting))) * 100% , where
the meter will have either a 5A or 1A current input. If users have Acuvim II meters with
Rogowski Coil (RCT), 333mV and mA type Current Inputs then they would use 1A in this
equation.
For example if the max primary power of your system is 576000W (or 576kW), your system is currently using 211kW and the meters current input type is 5A, then the load percentage would be calculated as follows:
Load Percentage = (211kW / (5 * 576kW)) * 100 = 7%

The rst page the user will see after selecting the Communications option under the Settings tab is the Network page. The network settings allow users to con gure all network
related settings including both Ethernet 1 and Ethernet 2 as well as WiFi.
8.1.1 RSTP Protocol
The AXM-WEB2 supports the RSTP protocol where users can daisy chain the Ethernet ports
on the AXM-WEB2 module to a network switch.
Users can con gure the meters IP manually or by setting the DHCP set as Auto.
NOTE: When the RSTP is enabled users will not be able to con gure Ethernet 1 and Ethernet
2, there is only 1 IP per meter using RSTP protocol.
Network Topology
Users can can daisy chain up to 32 devices using the RSTP protocol. This can cut down the
amount of network switches required in di erent applications and allows the use of 1 network
switch/router to be used with up to 32 devices. Each device can be accessed by con guring a
unique IP address or having the IP addresses assigned automatically by the network.

8.1.2 VLAN
Virtual Local Area Network (VLAN) allows devices under the same physical network to be
grouped (by VLAN ID) and act as if they are in separate networks. VLANs are isolated from
one another where trac stays private in the same VLAN.
When VLAN of an interface is enabled, it allows the AXM-WEB2 module to communicate with
other devices under the same VLAN without a VLAN switch, via this interface. In other words,
the module can parse IEEE 802.1Q-tagged Ethernet VLAN frames by itself.
Users can enable VLAN from the web interface under either the Ethernet 1 or Ethernet 2 set-
tings, once enabled a VLAN ID is required.
One of the common uses is when RSTP is enabled, the module can be put between two
VLAN switches, where both ETH1 and ETH2 ports connecting to switches' trunk ports. In this
method, the module can still forward all trac between the switches; while other devices in
the same VLAN can have access to the module, and no additional switch is required.
