The DCON/Modbus RTU Command Sets
6.1
Communicating with the ZT-2000 I/O Device
ICP DAS ZT-2000 I/O devices can operate using both the DCON and the Modbus
RTU protocol. Adjust the DIP switch number 2 to select the DCON or Modbus
RTU protocol and reboot the ZT-2000 I/O device to correct protocol.
6.2
The DCON Protocol Command Set
All ZT-2000 I/O series devices are controlled via wireless broadcast commands,
so each device must have a unique address that is saved in the EEPROM of the
device to denote the difference.
Consequently, all command and response formats contain the destination
address of the module. When an I/O device receives a command, it will
determine whether or not to respond based on the address contained in the
command. However, there are two exceptions, #** and
~
** commands.
