Expanded RTU Read Map
The expanded view of the
RTU Read Map
contains the same parameters as on the original page in
addition to a few more parameters.
For each remote register to be read, enter the register type, remote register format, remote register
number, and device number (remote unit number). Referring to the screen image, the following
parameters may be set using this screen:

Scale
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 is multiplied by the scale factor and added to the offset.
The final result is written to the local register number selected.
Periodic Poll Time: Determines how often the Gateway Pro or Gateway/Ethernet Bridge pair read
the remote registers of the Modbus slave device. Setting the periodic poll time to zero sets the
Gateway Pro or Gateway/Ethernet Bridge pair to read the remote registers continually.
Read Fail Count: When the read fail count is not zero, the default value is stored in the local
register after the given number of read failures. Setting the read fail count to zero disables the
default and the register retains the most recent value.
Register Type: Selecting
None
for register type negates the map though it remains in the list until
deleted. Unused maps always show
None
as the type. If the displayed maps are used and more are
needed, increase the RTU Read Maps Enabled number.
Other Commands
Insert/Delete buttons: Clicking the Delete button removes the map number shown in the Map
# box. Clicking the Insert button inserts a new map ahead of the map number shown. It is not
necessary to use the Insert button to add maps to the bottom of the list or to define any rule with
None
as the register type.
Prev and Next buttons: Scrolls through the maps/rules.
Update button: Sends new data or settings to the Ethernet Bridge or Gateway Pro.
