Hey @nada, have you tried using Emulation to make a Modbus or OPC UA connection with your Red-Node client? I noticed in this post that they had successfully made a connection using Modbus.

You could use HTTP queries to communicate between a Node-RED server and FlexSim.

To call a Node-RED server from FlexSim, use an HTTP In node (cookbook.nodered.org) and call it via the Http FlexScript API (docs.flexsim.com).

To call FlexSim from a Node-RED server, use the FlexSim Webserver (docs.flexsim.com) to listen for instance queries and an http request node (cookbook.nodered.org) to send them.

Hey @nada, you can read the speed of a conveyor using the " currentSpeed" property on a conveyor. If you have a reference to a conveyor, you can call it's properties to get and set properties on it.
