Basically, are you sure that the Slave Id, Serial communication parameters and the ModBus table are correct?

With ModBus Poll, you can test connection data by logging data into Excel.

If you have experience in communication lines and protocols, I recommend using web based scada. In this scada system, you have the chance to follow the data on both large screens and small screens such as HMI.

I have the following document. If you need it, I can share. "GenComm Communications Protocol for use with 550,555, 5210 and 5220 controllers."

Bluetooth optical converters to read the electric meter uses extensively in Turkey.

You can do it over Wi-Fi instead of over Bluetooth. Wi-Fi ModBus gateways are available on the market. It does not have to be a wireless modem in the environment. You can connect to Wi-Fi network with "Access Point" mode of Wi-Fi Modbus Gateways and view the data of your device via mobile...

Can you give us information about the device? Is the device battery powered or powered by external power? Is the communication protocol MQTT? If it is MQTT, which broker will be sent the data. Or will the data be sent to the IoT platform. Ex: Azure IOT, AWS IOT, Thingworx, etc. I don't know...

Hi, In terms of measurement, the iot sensor is no different from an ordinary level sensor. The basic feature of the IOT sensor is that it is easy to transfer the measured data to software systems. The most important issue in measuring devices is the condition of the measuring device being...

Hello, Does your IoT convert the ModBus protocol to MQTT? If this is the case, is it possible to remove the PLC? Your IoT device will read the data via ModBus and send the data to the broker (with MQTT protocol). In some new PLCs, the MQTT protocol may be embedded.
