Emulation issue with Modbus TCP (Catching exception) and NodeRED

Hello all,

I'm trying to make FlexSim send information to a NodeRed flow using Modbus TCP where FlexSim is the Server and a node in my flow is the client. The thing is I don't know how to properly configure the Emulation tool in FlexSim. I followed the instructions from here: https://docs.flexsim.com/en/21.2/Reference/Tools/Emulation/Emulation.html.

My objective is to send something when a box enters the Testing Station.

This is the error I obtained:

This is what I have done for configuration:

This is my flow in NodeRed:

This is my client node:

Software Version:

FlexSim 24.0.2

You configuration seem correct.

Could tou try to change the roles: Flexsim as client and Nodered as server?

Hello, thanks for the answer. I imported your flow from the other question and tried to connect to my flexsim simulation but it didnt work. Could you please provide more detail? It's my first time using flexsim. Thank you in advance.
