Is it suitable to run a MQTT Broker for small amounts of data on a WAGO PLC?

- Which HW size is the minimum recommendation?
- Which broker would you recommend?
- Are their any guides or test-result available?

Depending on the number of msg/s you could use a WAGO PLC like PFC200/PFC300 or Edge Controller.  
You can install [Mosquitto](https://hub.docker.com/_/eclipse-mosquitto), which would be my first choice for an embedded system.  
Take a look to [EMQX](https://www.emqx.com/en) also.  
You can use a MQTT client software like [MQTTX](https://mqttx.app/) which has a script mode, you can then generate a bigger load and see how CPU is handling it (with command line tool htop for instance).

I often use: [eclipse-mosquitto - Official Image | Docker Hub](https://hub.docker.com/_/eclipse-mosquitto)  
Its only about 8MB, so you dont need to use docker with SD card

Quick run:

1. Connect to console using PuTTY and paste:

```auto
mkdir mosquitto mosquitto/data mosquitto/log mosquitto/config
nano mosquitto/config/mosquitto.conf

```

1. To mosquitto.conf paste:

```auto
listener 1883
listener 9001
protocol websockets
persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log

allow_anonymous true

```

1. Run container:

`docker run --restart always --name mosquitto -p 1883:1883 -p 9001:9001 -v ./mosquitto/config:/mosquitto/config -v ./mosquitto/data:/mosquitto/data -v ./mosquitto/log:/mosquitto/log -d eclipse-mosquitto`
