====== IP Basic Settings & Configuration ======

===== IP Basic Settings =====

Before delivery, each Series 52 system is configured with an IP basic setting. This setting has a certain pattern, unless the customer indicates different requirements in his order.

Each controller with an integrated Ethernet interface has a dedicated network address, the so-called MAC address (''MAC - Media Access Control''). This address is always unambiguous and unique. DHD owns the MAC address range ''00:0A:63:00:00:00'' to ''00:0A:63:FF:FF:FF'', therefore this address is also referred as serial number of a DHD device.

A network-compatible controller module is always identified in a network by its MAC address. As the first 3 Bytes of all DHD MAC addresses always are identical, only the last 3 Bytes are indicated in DHD software applications.

**Note**\\  If you find the term "MAC address" in the context of a DHD system, it always refers to the last three Bytes of the actual address, although this is, strictly speaking, incorrect.

**Important**\\  These last 3 Bytes of the MAC address are used for generating the IP address for the basic setting.

Find below an example for the MAC address 10:00:02

  * Every single Byte is translated into the decimal format: ''10h = 16, 00h = 0, 02h = 2''
  * Afterwards the decimal numbers are strung together; 10 is prepended, and all numbers are separated by periods: ''10.16.0.2''

The subnet mask is automatically set to ''255.0.0.0'', according to the classification of this IP range.

Thus the following IP basic setting results for the example device:

  * ''IP address: 10.16.0.2''
  * ''Subnet mask: 255.0.0.0''
===== IP Configuration =====

The IP settings of a Series 52 system are defined directly in the systems communication controller. To set IP parameters, use the ''Maintenance Window'', an application, which is implemented in [[tb5:start|Toolbox5]], [[tb8:start|Toolbox8]], [[sx:start|SXConfig]] and [[dx:start|DXConfig]]. 

You can open the Maintenance Window by clicking the according command in the ''View'' menu or by pressing ''F7'' on your keyboard.

In the ''Device'' menu, select ''Network Config...''.
