    node-red-contrib-cip-ethernet-ip

    A Node-RED node to interact with Allen Bradley / Rockwell PLCs using the EtherNet/IP protocol. Based on the awesome work of cmseaton42/node-ethernet-ip.

    This node was created as part of the ST-One project.

    Install

    You can install this node directly from the "Manage Palette" menu in the Node-RED interface.

    Alternatively, run the following command in your Node-RED user directory - typically ~/.node-red on Linux or %HOMEPATH%\.nodered on Windows

        npm install node-red-contrib-cip-ethernet-ip
    

    NodeJS version 10 or greater and Node-RED version 1.0 or greater is required.

    Usage

    Each connection to a PLC is represented by the ETH-IP Endpoint configuration node. You can configure the PLC's Address, the variables available and their addresses, and the cycle time for reading the variables.

    The ETH-IP In node makes the variable's values available in a flow in three different modes:

    • Single variable: A single variable can be selected from the configured variables, and a message is sent every cycle, or only when it changes if diff is checked. msg.payload contains the variable's value and msg.topic has the variable's name.
    • All variables, one per message: Like the Single variable mode, but for all variables configured. If diff is checked, a message is sent everytime any variable changes. If diff is unchecked, one message is sent for every variable, in every cycle. Care must be taken about the number of messages per second in this mode.
    • All variables: In this mode, msg.payload contains an object with all configured variables and their values. If diff is checked, a message is sent if at least one of the variables changes its value.
