The slave network is used for communication of the iSMA-B-FCU device with the upper-level systems (for example, BMS). Communication can be realized by the Modbus RTU/ASCII or the BACnet MS/TP protocol (depends on the PROTOCOL DIP switch configuration).

The SlaveNetwork component is used to manage the BACnet MS/TP or Modbus RTU/ASCII protocols, using the RS485 port. The SlaveNetwork component has to be placed under the Drivers component.

The SlaveNetwork component

The SlaveNetwork component has the following slots:

  • Status: indicates the network status;
  • Fault Cause: shows the fault cause description;
  • Baudrate: indicates the baud rate of communication (set by the PROTOCOL DIP Switch);
  • Data Bits: displays the number of data bits; the default value is 8;
  • Parity Bits: configures the parity bits: Parity_Disabled, Odd, Even;
  • Stop Bits: displays the number of stop bits; the default value is 1;
  • Protocol: displays the protocol used for communication: Modbus or BACnet (set by the PROTOCOL DIP switch);
  • Slave Address: displays the actual address of the device (set by the MAC DIP switch);
  • Device Name: sets the BACnet device name;
  • BACnet Id: displys the actual BACnet Id; the default value equals to 826000 + Slave Address. The BACnet Id can be set using the Set BACnet ID action.

The SlaveNetwork component offers the following action, available in the context menu:

  • Set BACnet ID: sets the BACnet ID of the device.
