2.4 Default Settings

The default settings in the Acuvim II series meter are as followed:

Ethernet 1 Ethernet 2 Wi-Fi (Access Point)

IP address 192.168.1.254 (Static)

DHCP (Dynamic IP address)

192.168.100.1 (static) Subnet Mask 255.255.255.0 255.255.255.0

Gateway 192.168.1.1 n/a DNS Server 1 8.8.8.8 n/a DNS Server 2 8.8.4.4 n/a Modbus Port 502 n/a

By default, Ethernet 2 is configured for DHCP allowing the network will dynamically assign its network properties. To view the Ethernet 2 IP address from the meter’s display the Acuvim II or Acuvim-L meter must be configured to the WEB2 protocol. The following explains how to change the meters protocol settings to work with the WEB2 series module:

2.5 Initializing

Chapter 3: Connection Method

3.1 Direct Connect to a Computer

The AXM-WEB2 series can be connected to a computer using a crossover cable (standard 568A).

The AXM-WEB2 series module supports Modbus-TCP and HTTPS Functions for this method of connection.

To connect the meter directly to a computer, the computers IP must be within the same subnet as the meters IP address. The following steps outline how to change the computers IP using a Microsoft Windows OS:

• Click on the Change adapter options

19V: 2.1.4 Revised: September 2024

Chapter 3: Connection Method

• From the Network Connections window, right click on the icon with the local area connection and select properties

• Select the icon that says Internet Protocol Version 4 TCP/IP

20 V: 2.1.4 Revised: September 2024

• The Internet Protocol Version 4(TCP/IP) Properties box will pop up

• Click on ''Use the following IP address'' and enter in an IP number so that meter and computer are in the same local network range. For example, if the meter has IP address of 192.168.1.254, then the computer must be assigned with an IP 192.168.1.xxx, where xxx can be any number but cannot be the same as the value the meter has.

21V: 2.1.4 Revised: September 2024

Chapter 3: Connection Method

• Once you have entered in the IP address, press the Tab key on your keyboard until you hit the bottom and click OK

• Before selecting the OK button make note of the IP address you have assigned to the meter and then press OK.

NOTE: The meter and computer cannot have the same IP address, they must be different

3.2 Direct Connect to a Router/Switch

The AXM-WEB2 series can be connected to a router or switch using a patch cable. The DHCP can be configured to Auto to have the router automatically assign the meter with an IP address or the DHCP can be configured to Manual to set an IP address and network settings manually by the user.

AXM-WEB2 and AXM-WEB2-D has two Ethernet ports, Ethernet 1 is set to have the static DHCP, and Ethernet 2 is set to have the dynamic DHCP. Both Ethernet ports have the same functionalities, which can be used according to the requirements.

3.3 Connect through Wi-Fi

The AXM-WEB2 and AXM-WEB2 FOLC can be connected through Wi-Fi network.

By default, the AXM-WEB2 and AXM-WEB2 FOLC will be in Access Point mode with default IP address of 192.168.100.1. Ensure the device connecting to the communication modules has DHCP enabled, or it should be in the same subnet. The module will appear in the Wi-Fi network

22 V: 2.1.4 Revised: September 2024 as AXM-WEB2-WIFI-(serial number of module) as the SSID or name of the wireless network. By default, the network key or password will be ''accuenergy''.

• Once connected to the network, open an internet browser and type in the IP address of the Wi-Fi module: 192.168.100.1

• Log in to the web interface, the default username and password is 'admin'.

3.4 Description of Modbus-TCP Protocol

The Modbus-TCP protocol is used as one of the communication protocols in the AXM-WEB2 series.

The protocol establishes a master and slave connection in Ethernet. The master device(client) first 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.

Chapter 3: Connection Method

3.4.1.3. Function Field

The function code field of a message frame contains eight bits. Valid codes are in the range of 1-255. When a message is sent from a client to a server device, the function code field tells the server what kinds of action to perform.

Code Length Description

01 Read Relay Output Status Obtain current status of Relay Output 02 Read Digital Input (DI) Status Obtain current status of Digital Input 03 Read Data Obtain current binary value in one or more registers 05 Control Single Relay Output Force Relay to a state of On or OFF

16 Write Multiple Registers Place specific value into a series of consecutive multiple registers

3.4.1.4. Data Field

The data field is constructed using sets of two hexadecimal digits, in the range of 00 to FF. The data field of messages sent from a master to slave contains additional information which the slave must use to take the action defined 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 registers (function code 03), the data field specifies 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 field specifies the starting register, how many registers to write, the count of data bytes to follow in the data field and the data to be written into the registers.

The user will need to access the AXM-WEB2 series web interface to configure the module and use its functions. The web interface allows for remote initial setup of the Acuvim II and Acuvim-L meters.

The AXM-WEB2 series web interface allows for different user access levels where multiple users and role configurations can be made.

To access the web interface the IP address for the WEB2 series module, either Ethernet 1, Ethernet 2 or a Wi-Fi IP address must be known.

4.1 User Access Login

Enter the correct IP address of the module in the search bar of the internet browser to access the web interface of the AXM-WEB2 series. The user will be redirected to a web page prompting to enter the User Name and the appropriate password for that user. It is recommended that no more than five users are logged in concurrently for this level to ensure optimal performance when using the web interface.

The default User Name is admin and the default password for this user name is also admin.

User Name: admin

Password: admin

4.2 User Configuration

The AXM-WEB2 series supports the creation of different users for the web interface. Each user can be assigned different roles to determine what permissions and functions users will have when logged in. To access the user configuration page, click on the User Management tab and select User Configuration.

The user configuration table provides information regarding the user access level, such as the register date, expiration date and last login time. If the correct permission is available for the account, the user will have the option to lock an account, and edit and delete users.

NOTE: Users cannot lock or delete an account they are already signed into.

New users can be added with available options to enter an user name, password, role, and option to set the password policy. The role determines the type of access the user will have on the user level created. Users have the option to override the default password policy which is a set of rules for allowable passwords on the AXM-WEB2 series interface, this includes length and complexity of the password (capital letters, number, special characters, etc.).
