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 RTU Read Map to read data from those devices. If the local object number is shown in parenthesis, it means that object is already mapped in the RTU Read Map.

For each remote register to be written, enter the register type, format, number, and unit ID. The local object number shown will be written to this remote register. Poll (update) time is set in the "RTU Device" page.

Selecting "none" for remote type will cause this rule to be skipped. Unused registers should have "none" indicated to avoid generating erroneous communication traffic.
