    In some cases, there is a need to synchronize the BACnet data from different sources such as the LCD display or the Modbus network. To do so in the iSMA-B-AAC20 controller, a special mechanism called link back forward needs to be used. This mechanism requires to use the NV component without connected In slot and in the auto mode.
