Operator Bitmap:
Functional Description:
The Modbus TCP Broadcaster generic hardware operator provides access to a networking channel resource in the physical hardware. When the generic operator is linked to a specific networking hardware resource, it will broadcast a message over that channel resource using the Modbus TCP protocol.
...
Structure - A structure may be a collection of boolean and floating point values. Each element of the structure, whether boolean or float, consumes two consecutive registers, with boolean structure members converted to and from floats. Structures are not likely to be supported on non-Chameleon hardware.
0% Mapping and 100% Mapping - the minimum and maximum range values used only when the Data Type (see above) is set to Mapped Range.
...
The initial value to be broadcast.
Reorder
Because the use of multiple registers to represent 32 bit and floating point numbers is not standardized in Modbus TCP, it is left to the manufacturer how the registers should be ordered. To accommodate other manufacturers, a means to alter the register ordering is provided. Normally, the default of HH-HL-LH-LL will work correctly; this will use the first register for the highest order bits and the second register for the lowest order bits.
Comments: None.
