Global Command Registers
This option allows you to specify global commands for all
the devices specified in the Device List. It is available only for
VDEW devices.
The Global Command Registers consist of six registers.
These registers allow the PLC to transmit commands to all
the devices in the Device List. To send a command, all the
PLC needs to do is to place the command values into the
appropriate PLC registers, which the DTU3005 unit reads
and then processes.

described in detail in
Appendix F
