Due to the pandemic we got a somewhat specialized request from a customer. They want to be able to test that the Modbus interface is functioning correctly before doing the final installation. Normally we'd travel to on-site and setup a PLC with simulation software to test that the function is correct. Due to the current circumstances we'd like to:
- Send data from Modbus RTU master to a cloud platform (or directly to another gateway/router)
- Receive that data to a Modbus RTU slave, and then respond back with additional data
Is it possible to use a gateway/router, for example a RUT955, to receive Modbus master data via the internet? Or can you only send data from it?
