DCON/MODBUS
Module
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.
