Rule number simply tells you where you're at on the list of register maps. Click "next" and
"prev" to scroll through the list. To advance directly to a specific map, enter the desired number
in the "Map #" box, then click Update.
The local object data may be written periodically, or when it changes, or both. To send upon
change (send on delta), check the first box and enter the amount by which the local object must
change before being written to the remote device. To guarantee that the remote register will be
written at least occasionally even if the data does not change, check the second box and enter
some amount of time. This time period will be referred to as the "maximum quiet time".
Data from the local object may be manipulated before being written to the remote register. The
local data is first multiplied by the scale factor. The offset is then added to it. If a bit mask is
entered, and the remote register type is signed or unsigned (16-bit data), the mask will be bit-
wise logical AND-ed with the data. The mask is right justified, then AND-ed with the data. The
result is then left shifted back to the original position of the mask. In other words, the least
significant bits of the original data will be stuffed at the position marked by the mask.
After the scaling and masking, the bit fill will be logically OR-ed into the result, but only if the
mask was nonzero and was used. Both mask and fill are entered in hexadecimal.
Multiple local objects may be packed into a single remote register. To accomplish this, define
two or more rules in sequence with the same remote destination. If the destination is the same,
data types are 16-bit (integer or unsigned), bit masks are nonzero, and the rules are sequential,
