# Configuration of DIAP for EthernetIP (Legacy)

**This protocol uses the "Legacy" Protocol engine.**

### PLC configuration

This is a short introduction only. Please see the article [Configuration of PLCs](https://6547305.hs-sites.com/knowledge/configuration-of-plcs?hsLang=en) for a complete guide.

1. Select Ethernet/IP to communicate with the industrial ethernet protocol (EIP).
2. Specify the **CPU type** and **IP** of the PLC.

### Tag configuration

Enter **Browse path, Reading number** and **Tag's textual name**.

The **Browse path** is required for LGX and optional for PLC/SLC/MLGX IOI path to facilitate access to the PLC from the DIAP gateway (Browse path is not necessary for SLC).

This example translates as BACKPLANE -\> SLOT 2.

**Example of accessing tag located in a program:**

![](https://kb.dataintel.dk/hubfs/Knowledge%20Base%20Import/eltronic.zendesk.comhcarticle_attachments360005638220Capture.png)

The syntax is "Program:\<ProgramName\>.\<Tag\>"

Browse path is set to 1,0 - 1 being the virtual backplane and always 0 for the controller
