When the remote register is read, data may be manipulated before being written to the local register. If a
bit mask is entered (in hexadecimal), and the remote register type is signed or unsigned (16-bit data), the
mask will be bit-wise logical AND-ed with the data, and the retained bits will be right justified in the result.
The result will then be multiplied by the scale factor. The offset is then added and this final result is
written to the local register number given. The name is optional and used only for display purposes.
The periodic poll time determines how often the remote register will be read. This number, if nonzero, will
override the default poll time given in the Devices page for the remote device being read.
The default value will be stored into the local register after the given number of read failures if the fail
count is non-zero. Setting the count to zero will disable the default, and the object will retain the most
recent value obtained.
Delete will remove the rule number shown in the "Map #" box. Insert will insert a new rule before the rule
number shown, and is used for placing rules between existing rules. It is not necessary to use Insert to
add rules to the bottom of the list or to define any rule presently having zero for a source object or
"none" for remote type.
Selecting "none" for remote type effectively deletes the rule even though it will still appear in the list until
deleted. Unused rules at the end of the list will always show none as the type. If you wish to prevent these
from being displayed, reduce the number of rules enabled.
The number of rules enabled simply limits the scope of rule review so that you do not have to review a lot
of unused rules. If the displayed rules are used up and you need more, increase the enabled number.
5.3 Modbus RTU Master Write Maps
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 "Showing" box,
then click Update.
Rules entered on this page only write data to remote devices. Go to the Client Read Map to read data from
those devices. The full parameter set is different for read versus write.
