07 Jul 2021


eManager is an IoT controller designed with eMOD technology for monitoring, control and automation applications. Node-RED is fully integrated on eManager’s product range, including customized nodes. Today we present an online Node-RED simulator as the best tool to program and test our industrial modular solution without needing hardware.

Node-RED Online Simulator Automation Industry Monitoring


What is this simulator?

We thought that the best way to show the added value of the customized nodes of our industrial modular solution eManager is to create an online simulator accessible for everybody.

This tool is a Node-RED node that simulates values for each of our eMOD modules. The first version includes the modules of 10 Digital inputs, 7 Analog inputs + 2 Power relays and 8 Signal relays.

What can I do with this Node-RED simulator?

eMOD & eManager simulator provides to our customers, or future customers smiley , two big advantages:

Application programming without hardware

It is common that inside a developing team different people work in the same project, and up to now each one required a physical device to program comfortably. With this simulator that will be no longer necessary because the simulator nodes have the same functions and features than the real nodes. Whatever you develop with the simulator it will be exportable to the final application.

Proof and test the eManager solution for free

The moment you have an IoT modular controller like eManager in your hands is when you can feel the ease with which you can program edge computing applications.

eManager’s Node-RED customized nodes allow to create an infinity number of applications, such as relating an analog value to an actuation on a relay, automating an activation of a digital output depending on a pulse counter value, reading a Modbus device and send its value via MQTT, control a BACNET device or even reed an OPC-UA server.

Node-RED, eManager and its expansion modules allow to offer smart solutions perfectly matched with each project needs.
