# Edge IIoT

> ![" "](IgnitionEdge-IIoT_137.png)

The Edge IIoT product now includes all [Compute](../ignition-edge.md#edge-compute), [Sync Services](../ignition-edge.md#edge-sync-services), and [EAM](../ignition-edge.md#edge-eam) features. Users with an existing Ignition Edge license and Upgrade Protection may have upgrades available. Contact your account representative for more information.

The IIoT product (formerly known as MQTT) allows this copy of Edge to push data directly into a Broker using the fast and lightweight MQTT data transfer protocol. In effect, this makes your computer (and whatever devices are attached to it) into a remote MQTT publisher. If you are already rolling out new smart devices that connect to your Broker, this allows you to connect all of your legacy devices into the same system.
IIoT product also allows UA clients to connect to the UA server on Edge.  

Edge IIoT activates the following modules:

- MQTT Transmission
- Opto22 SNAP PAC driver

## Remote Tag Provider

With Edge IIoT installed, Ignition Gateways will be able to [create remote Tag Providers](../edge-gateway/configuring-sync-services.md#remote-tag-provider), targeting either the system provider or the one realtime Tag Provider on an Edge Gateway.

For more information about remote Tag Providers, see [Tag Providers](platform\tags\tag-providers\tag-providers.md).

## Expose Edge’s UA Server

The IIoT product enables UA clients to connect to the UA server on Edge. Applying this product will require that the OPC UA module is restarted before the UA server will be available publicly. 

:::note Prior to 8.1.40
If using a version earlier than 8.1.40, the MQTT Transmission module is required to expose Ignition's OPC UA server when your Gateway is licensed. The procedure [below](#install-the-mqtt-transmission-module) describes this process.

## Install the MQTT Transmission Module

Prior to 8.1.40, the MQTT Transmission module from Cirrus Link was needed to activate the IIoT product, but now all built-in OPC UA server functionality is directly available. However, the MQTT Transmission module is still required to leverage the third-party modules listed on the [Strategic Partner Modules](https://inductiveautomation.com/downloads/third-party-modules/) page.

1. Download the MQTT Transmission module from the [Inductive Automation](https://inductiveautomation.com/downloads/third-party-modules/) website.

2. Go to the **Config** tab of your Edge Gateway to access the **System** > **Modules** page. 

4. On the **Modules** page, scroll down and click on **Install** or **Upgrade a Module...**

6. Navigate to the folder where you downloaded MQTT-Transmission-signed.modl, select the file, and click **Open**.
7. Click the **Install** button. 
8. At the License agreement, select **I accept the terms in the License Agreement**, then click the **Accept License** button.
9. At the Trusted Certificates window, click **I want to add this certificate to my trusted certificates and install the module**.
10. Click the **Add Certificate and Install Module** button.

## Install IIoT Opto22 SNAP Pac Driver or the Emerson ROC Driver

To install the Opto22 SNAP Pac driver or Emerson ROC driver: 

1. Download the driver you want from the [Inductive Automation](https://inductiveautomation.com/downloads/third-party-modules/) website. 
2. Go to the **Config** tab of your Edge Gateway to access the **System** > **Overview** page.

3. Scroll down and click on **Install** or **Upgrade a Module...**
4. Next click on **Choose file**.
5. Navigate to the folder where you downloaded the driver(s) and select the file.
6. Click the **Install** button. 
7. At the License agreement, select **I accept the terms in the License Agreement**, then click the **Accept License** button.

You'll now see a message indicating the driver module was successfully installed and the module is now available on the Module Configuration page in the Edge Gateway. For example, the following image shows the Opto22 SNAP Pac driver installed.
