3. At the Port Number selection, enter a source port

that is not being used by another NIM on the

same network (such as 7701, 7702, 7703, and so

on). Keeping a list of the network modules on a

particular network along with the source ports of

those modules will ensure that duplicate source

ports are not used.

To use this datagram type, program it in the following

order:

1. Confirm that D6200 version 1.20 or later is

installed.

2. Confirm that the D6600 CPU version 01.02.01 is

loaded in the receiver.

3. With the D6200 software, select Network Æ

Network Configuration Management Æ

Read/Manage Network Configuration from

Receiver.

4. At the Datagram selection, enter 07 and press

[Enter].

5. At the Remote Port selection, enter the port

number that is used in the D6680/D6682 for the

D6600.

4. Select the 6.8 Global Parameters tab.

5. Change the 6.8.6 6600 Datagram Type value to

6. Save the settings and exit from the setup of the

NIM.

6. Send the changes to the receiver and close the

window.

Outgoing packets from a network over a single IP

address go through a router or firewall that uses NAT

tables to keep track of which packets come from

which internal IP addresses. The NAT table ensures

that the returning packets for a device are forwarded

to the device that sent out the first packet. An

example of this is multiple PCs on a network

connecting to the Internet through a single IP address

from an ISP. By using the same idea, network

devices can perform the same function.

7. Select Network Æ Network Utilities Æ Network

Device Setup and select the Telnet to Device

tab.

8. Type or find the IP address of the D6680/D6682

in the list and establish a telnet session with the

D6680/D6682.

9. After establishing the telnet session, select the

channel(s) to use by pressing [1] or [2], and then

press [Enter].

Table 3 on page 11 shows an example of what the

NAT table remembers when packets are sent to a

destination. An outgoing packet is sent to an IP

address with Source and Destination ports in that

packet. The Destination port is the port number that

the device uses when it receives data. After receiving

the data, the device processes it and sends a packet

back to the IP address that sent the data.

10. Press [Enter] until you have selected Datagram

and type 02, then press [Enter]. If both channels

are used, change both channels.

11. Save the settings and exit from the D6680/D6682

setup.

3.3.2 Datagram 07

Table 3: NAT Table

This datagram is supported only on the

E2-RAD version of the D9133TTL-E

Network Interface Module.

Internal IP Address Source Port

192.168.1.11 7700

This datagram type is used only in the NIM of the

network device (D9133TTL-E, or DX4020). The

datagram type allows the Source and Destination

ports to be set independently. This use of a different

source port allows NAT (Network Address

Translation) tables of routers or firewalls to direct

packets to the correct NIM of the field device.

192.168.1.12 7701

192.168.1.13 7702

When the data is returned to the router or firewall

software, the NIM directs the returning packet to the

correct internal IP address based on the NAT table.

To use this datagram type, program in the following

order:

1. Telnet to the NIM of the field device as described

in the appropriate network device (D9133TTL-E

or DX4020) installation guide.

2. Select channel 1 of the NIM.
