DCON/MODBUS Device Communication
ZigBee is defined as a low-power and low data rate wireless transmission
protocol. In order to prevent excessive transmission loading to the ZigBee
network, there is an advanced setting to the Gateway Mode to set the wireless
frame type, which is used to select either the Broadcast Frame or Unicast Frame
to transmit data.
Once the Unicast Frame is selected, the Address of DCON or Modbus
instructions will be regarded as the destination address to the ZigBee. So, the
DCON/Modbus devices should be connected to corresponding address of
ZigBee module.
