Hi,

I taken a look the your video.

To connect Flexsim to node-red directly I installed the 'node-red-contrib-modbus' palette. This palette provide a set of nodes to read/write data using modbus and a node to create a modbus server.

Below a JSON of a simple flow that create a server and write a coil (manually): this coil's changes can be read by FlexSim using the a Modbus TCP control variable.

Copy this code and import in your node-red.
Let me know if this solve your question.
