Regarding MODBUS communication through an MQTT broker.

[CesarCastillo-90]

Hello everyone, I hope you are well. I have the following case: This code is the MODBUS response that I receive through the MQTT topic.

{"id":"26cd17d9-aa6d-45d7-b3dc-1fd5fadd5ca1","device":"Modbus-TCP-Device-2","created":1607981337586,"origin":1607981337581736137,"readings":[{"id":"77437133-9d56-4b5a-8445-ca19cd39b902","origin":1607981337473057323,"device":"Modbus-TCP-Device-2","name":"DemandWindowSize","value":"500","valueType":"Uint16"},{"id":"2345f849-0f64-4ada-9ba6-cf3b40ad6710","origin":1607981337581112262,"device":"Modbus-TCP-Device-2","name":"LineFrequency","value":"120","valueType":"Uint16"}]}

However, I don't know how to post to the topic to upload data to the ModbusPal simulator. I appreciate the guidance you can give me, I look forward to your valuable comments.

How can I publish a data from the MQTT broker to the MobdusPal simulator?

Please use app service to push data to MQTT broker
