# Node-RED for Ignition

## Overview

Node-RED nodes for interfacing to Ignition by Inductive Automation. Allows for the reading and writing of tags configured in Ignition.

Requires [Node-RED Ignition Module](https://github.com/IgnitionModuleDevelopmentCommunity/IgnitionNode-RED/blob/master/Ignition-Node-RED-Module-signed.modl) and Ignition 7.9.3 or later.

These nodes are provided for installation version compatibility when using grv-epic-pr1-2.0.x firmware which includes ignition and ignition-edge gateway software 7.9.14.

For ignition 8.0 installation use the updated node-red-contrib-ignition-nodes

## Install

Run the following command in your Node-RED user directory:

    npm install node-red-contrib-ignition-nodes

## Usage

The Tag Read node can read the value of any tag in Ignition. This includes all Gateway tags (OPC, memory, expression, SQL, derived, UDTs) and System tags.

The Tag Write node can write to tags in Ignition. This will only work with tags that are configured with write privileges.
