future to swap the bytes of word and double-word
values when floating-point data is required.
5095 45096 Device Index This parameter associates the command with a
device defined in the device definition table
(Device[ ] in the MBPlusModuleDef object). The
index defined in this parameter sets the route path
defined for the device in the Modbus Plus
message.
