Requires version 25 of the DIAP. Benefit of the "Optimized" protocol engine is that it is able to automatically discovery the tags from the PLC.** ### 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. Select "**Optimized**" as the Protocol Engine. 3. Enable "**Tags names autodiscovery**" for the DIAP to discovery available tags from the PLC 4. Specify the **CPU type** and **IP** of the PLC **(!)** Only compactlogix and controllogix are included in the optimized protocol engine ![](https://kb.dataintel.dk/hubfs/Knowledge%20Base%20Import/eltronic.zendesk.comhcarticle_attachments360014366959mceclip6.png) ### Tag configuration Enter "**Tag's textual name"**. The "**Tag's textual name"** will automatically start filling out the text and suggest available tags from the PLC. ![](https://kb.dataintel.dk/hubfs/Knowledge%20Base%20Import/eltronic.zendesk.comhcarticle_attachments360014366839mceclip5.png) **Example of accessing a tag with Optimized protocol** ![](https://kb.dataintel.dk/hubfs/Knowledge%20Base%20Import/eltronic.zendesk.comhcarticle_attachments360014375280mceclip4.png) **After you have started writing the name of the tag, then the protocol will automatically suggest the findings from the PLC** ![](https://kb.dataintel.dk/hubfs/Knowledge%20Base%20Import/eltronic.zendesk.comhcarticle_attachments360014375260mceclip3.png) **Chose the correct tag and press "Save changes"** - [DIAP Gateway](https://kb.dataintel.dk/diap-gateway?hsLang=en#main-content) - [Getting Started](https://kb.dataintel.dk/diap-gateway?hsLang=en#getting-started) - [Troubleshooting](https://kb.dataintel.dk/diap-gateway?hsLang=en#troubleshooting) - [Known issues/limitations](https://kb.dataintel.dk/diap-gateway?hsLang=en#known-issues-limitations) - [General](https://kb.dataintel.dk/general?hsLang=en#main-content) - [FAQ](https://kb.dataintel.dk/general?hsLang=en#faq) - [Configuration](https://kb.dataintel.dk/configuration?hsLang=en#main-content) - [FAQ](https://kb.dataintel.dk/configuration?hsLang=en#faq) - [Troubleshooting](https://kb.dataintel.dk/configuration?hsLang=en#troubleshooting) - [Guides](https://kb.dataintel.dk/configuration?hsLang=en#guides) - [Protocols](https://kb.dataintel.dk/configuration?hsLang=en#protocols) - [Live/Real time site](https://kb.dataintel.dk/live-real-time-site?hsLang=en#main-content) - [Getting Started](https://kb.dataintel.dk/live-real-time-site?hsLang=en#getting-started) - [FAQ](https://kb.dataintel.dk/live-real-time-site?hsLang=en#faq) - [Guide](https://kb.dataintel.dk/live-real-time-site?hsLang=en#guide) - [Features](https://kb.dataintel.dk/live-real-time-site?hsLang=en#features) - [OEE site](https://kb.dataintel.dk/oee-site?hsLang=en#main-content) - [Getting Started](https://kb.dataintel.dk/oee-site?hsLang=en#getting-started) - [FAQ](https://kb.dataintel.dk/oee-site?hsLang=en#faq) - [Guides](https://kb.dataintel.dk/oee-site?hsLang=en#guides) - [Configuration](https://kb.dataintel.dk/oee-site?hsLang=en#configuration) - [Remote Access](https://kb.dataintel.dk/remote-access?hsLang=en#main-content) - [Getting Started](https://kb.dataintel.dk/remote-access?hsLang=en#getting-started) - [FAQ](https://kb.dataintel.dk/remote-access?hsLang=en#faq) - [Guides](https://kb.dataintel.dk/remote-access?hsLang=en#guides) - [API](https://kb.dataintel.dk/api?hsLang=en#main-content) - [API](https://kb.dataintel.dk/api?hsLang=en#api) - [Release information](https://kb.dataintel.dk/release-information?hsLang=en#main-content) - [DIAP Release Notes](https://kb.dataintel.dk/release-information?hsLang=en#diap-release-notes) - [Live/Real time site](https://kb.dataintel.dk/release-information?hsLang=en#live-real-time-site) - [OEE site](https://kb.dataintel.dk/release-information?hsLang=en#oee-site) - [Management site](https://kb.dataintel.dk/release-information?hsLang=en#management-site) - [DIAP Gateway](https://kb.dataintel.dk/release-information?hsLang=en#diap-gateway) - [Default HubSpot Blog](https://diap-6547305.hs-sites.com/blog) [![Chill listening crop-3](https://kb.dataintel.dk/hs-fs/hubfs/Sk%C3%A6rmbillede%202021-05-04%20kl.%2017.46.04.png?width=221&height=26&name=Sk%C3%A6rmbillede%202021-05-04%20kl.%2017.46.04.png "Chill listening crop-3")](https://diap.hubspotpagebuilder.com/-temporary-slug-5b226bcb-69c8-45c1-82ff-e060e2d4037d?hsLang=en) Copyright © 2026, Data Intelligence A/S
