1.4.3.3 Setting Up a MODBUS/TCP Connection
A modified XMT868i can use the MODBUS/TCP interface to communicate with an internal network. An optional
MODBUS/TCP card with a unique MAC (IP) address (installed only in slot 2) includes an RJ45 connector. To connect
the MODBUS/TCP-enabled XMT868i to the network, insert the jack of an RJ45 cable into the RJ45 connector, route the
cable through a conduit hole with an appropriate cable clamp, and wire the other end of the cable to the LAN
according to the manufacturer’s instructions.
To establish MODBUS/TCP communications with the XMT868i, you must install the
Ruiping software utility (available
with your modified XMT868i) on a PC connected to the LAN. Once installed and running, the software displays all
Ethernet devices currently connected to the subnet. You can identify the XMT868i by its MAC address, supplied as
part of customer documentation. The default TCP Port is 502.
The default IP addressing for the XMT868i is DHCP (dynamic). If you need to assign a static IP address to the XMT868i,
complete the following steps:
IMPORTANT: To assign a static IP address, the XMT868i must be connected to an Ethernet network with a dynamic
address assignment mechanism (DHCP) first.
1. Run Ruiping software, and identify the XMT868i’s current IP address.
Note: “Ruiping-e” will return the found IP addresses as well as the MAC address.
2. From a DOS command prompt, type: telnet “ip address” 10000
3. The “Welcome to Net+Works Configuration Utility” opens. Type in the login name and password.
a. Login:
type
root
.
b. Password : type Netsilicon .
4. In the Main Menu:
a.
Select
IP Parameters (1)
. Enter the desired IP changes and return to the Main Menu.
b. Select Enable DHCP Client (3) . Select N (2) to disable, then select 4 for Main Menu.
c. At the Main Menu, select 4 for Quit . Power cycle the XMT868i (i.e., turn the meter off and on) to apply the
changes.
Refer to the section Requesting Parameters Using MODBUS on page 39 to retrieve data from the XMT868i using
MODBUS.
