44 l Configuring Ethernet Gateway communications

Configuring Ethernet Gateway communications

Select this option if Modicon’s EMBP Gateway bridges your computer’s TCP/

IP Ethernet to your controller’s Modbus Plus network. Once configured for an

Ethernet Gateway, NxT behaves as if it were connected directly to a Modbus

Plus network.

Ø To select and configure Ethernet Gateway communications:

1. From the ProWORXNxT Title Screen or from the Offline Network

Editor, on the Controller menu, click Communications Setup.

2. From the Interface list on the left of the Communications Setup dialog

box, select Ethernet Gateway.

3. Enter your settings, then click OK:

Ÿ Gateway IP Address: The TCP/IP address of the computer linking

your PC’s Ethernet to your controller’s Modbus Plus network.

Ÿ Timeout: Specifies the length of time the PC will wait for successful

communication with a controller before displaying an error

message. Default is 2 seconds.

Configuring TCP/IP communications

Some controllers can be equipped with TCP/IP cards. Select this option if both

your computer and controller use TCP/IP networking, regardless of whether

they are on the same network or are connected by a gateway.

If you use TCP/IP networking to connect to your controllers:

Ÿ The Select Device dialog box doesn’t accept controller addresses

unless they are in standard TCP/IP format: four numbers ranging

from 0 to 255 separated by periods (for example, 10.0.254.68 is valid).

Ÿ The Net Scan function in Select Device dialog boxes is unavailable.

Your computer’s Ethernet address is set in Windows by your network

administrator (as is its sub-network mask address, if necessary).

Your PC’s TCP/IP address is set in Windows by your network administrator (as

are the gateway and sub-network mask addresses, if necessary).
