Can you provide a TLS example usage ?

Hello,

First of all, thank you very much for this project.

I am already using it as a Modbus TCP slave to receive Modbus frames from devices, then map the data into a JSON object and publish it to a Kafka topic.

I now need to add TLS support for secured devices. Would it be possible to share an example showing how to set up a Modbus TCP slave with TLS enabled?

Thank you very much in advance.

I actually set up a little CLI with client and server for testing Modbus security: https://github.com/kevinherron/modbus-security-cli

The server setup is in here: https://github.com/kevinherron/modbus-security-cli/blob/main/src/main/kotlin/cmd/ServerCmd.kt

You should be able to use that Docker image to aid in testing your implementation.

Thank you very much, I’ll take a look at it.

Ok, I was using the old “modbus-slave-tcp” library (v1.2.2).
I’m trying to migrate to the modbus-tcp library (v2.1.3), but I’m running into issues due to all the breaking changes involved 🙂
I’ll continue to investigate.

Thank you very much for your help.
