6.7 Setting Up a
MODBUS/TCP
Connection
A modified GC868 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 slots 5 or 6) includes an RJ45 connector. To connect the
MODBUS/TCP-enabled GC868 to the network, insert the jack of an RJ45 cable into
the RJ45 connector, route the cable through the bottom of the GC868, and wire the
other end of the cable to the LAN according to the manufacturer’s instructions.
To establish MODBUS/TCP communications with the GC868, you must install the
Ruiping software utility (available with your modified GC868) 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 GC868 by its MAC address,
supplied as part of customer documentation. The default TCP Port is 502.
The default IP addressing for the GC868 is DHCP (dynamic). If you need to assign a
static IP address to the GC868, complete the following steps:
IMPORTANT: To assign a static IP address, the GC868 must be connected to an
Ethernet network with a dynamic address assignment mechanism
(DHCP) first.
1. Run Ruiping software, and identify the GC868’s current IP address.
Note:
“Ruiping-e” will return the found IP address 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 GC868 (i.e., turn the
meter off and on) to apply the changes.
