Device Settings

On this page, the user can change the Device Mode, Web Interface Password, and download or upload the device's configuration and rules files.

The device has four modes:

  • Transparent Mode
  • Master Mode
  • Master - Data Collector Mode
  • Slave Mode

DeviceSettings-ISM842

Transparent Mode​

In this mode, the device sends data coming from RS485 or the ethernet port to other ModProBus devices. The receiving ModProBus devices send the data coming from other ModProBus devices directly to both RS485 and the ethernet port.

On the ethernet side, the device acts like a TCP server (if enabled in Modbus Settings) and users can connect to this server as clients.

Master Mode​

In this mode, the device sends Modbus data coming from RS485 or the ethernet port to the ModProBus devices registered in Devices Settings. The Slave device(s) send the data received from the Master device to the Modbus devices registered in it via RS485 or the ethernet port. After the Slave device(s) receive the data from RS485 or the ethernet port, they send a response to the master device regarding this. On the ethernet side, the device acts like a TCP server (if enabled in Modbus Settings) and users can connect to this server as clients.

Master - Data Collector Mode​

In this mode, the device sends the Modbus queries registered in it (from the Rules tab) to the devices connected to it or other ModProBus devices using RS485 or the ethernet port. The receiving device(s) send a response to the Master device by querying the registered configuration in Devices Settings via RS485 and the ethernet port after receiving the incoming data. There can only be one master on the same network. On the ethernet side, the device acts like a TCP server (if enabled in Modbus Settings) and users can connect to this server as clients.

Slave Mode​

In this mode, the device receives data from the Master device and sends a response to the Master device by querying the registered configuration in Devices Settings via RS485 and the ethernet port. There can be multiple slaves on the same network. On the ethernet side, the device acts like a TCP server (if enabled in Modbus Settings) and users can connect to this server as clients.
