Configuration Parameters for IP Addresses

Introduction

On the IP Configuration tab, you can define the IP address of a module in the IP Address Configuration zone. The options are:

Configured: Manually enter the IP address, subnetwork mask, and gateway address.
From a server: The configuration is supplied by a server device.

NOTE: To configure IP addresses, obtain the appropriate network address and subnetwork mask from your system administrator. Elsewhere in this guide is detailed information for IP addressing.

Configured IP Address

Selecting the Configured field allows manual configuration according to your own requirements:

IP Address: The IP address of the module
Subnetwork mask: The mask defines the part allocated to the subnetwork identifier in the IP address.
Gateway Address: The gateway address is the IP address of the default gateway to which messages for other networks are transmitted.

NOTE: If the module is connected to an existing TCP/IP network, the IP addresses are administered globally, therefore the IP parameters must be configured. Otherwise there is a risk of disturbance on the existing network caused by possible double allocation of the IP addresses.

From a Server

Selecting the From a server field allows the module's IP address to be configured from a remote device acting as a DHCP/BOOTP server. When the From a server button is active:

Leaving the Device Name field empty facilitates communications that are compatible with any setting on the rotary switches.
To use a device name in the Device Name field, set the lower rotary switch to its STORED position. If you set the switch any other position, the result depends on the setting of the lower rotary switch, as described in the Ethernet Port Status table.
The configured IP parameters have no effect and are grayed out.

NOTE: The M340 Ethernet modules will not receive an IP address from a BOOTP/DHCP server on application download if the IP configuration has not changed.

NOTE: The maximum length for the device name is 16 characters. Valid characters include alphanumerics (0 to 9, A to Z) and underscores.
