Instruction Manual
Network Tab
The example screen image shows two local registers using the bit field to be copied to one mapped
register. The result of the bit field mapping when register 17 contains 005A and register 18 contains
003C is to map the results, 3C5A to register 500.
Exclusivity: Enter the number of Modbus registers available in your customized register mapping
and select the User Map Enabled checkbox to begin using a customized map. Select the Map
is Exclusive checkbox if the access to registers outside this map is prohibited. If the Map is
Exclusive checkbox is not selected, all local registers not overlapped by the custom map will be
accessible to the remote client.
Local Register Number: The Local Register Number is the source of the data.
Mapped Register Number: The mapped register number is the destination register for the data to
be copied to.
Mapped Register Format: Select the mapped register format: integer, unsigned, double, float, or
bit. An integer is a 16-bit (signed) number, an unsigned format is a 16-bit unsigned number, double
refers to a double precision (32-bit) value, a floating value is a floating point number, and a bit value
is a single bit that can either be a 0 or a 1 (discrete value.)
Selecting
None
for the register format negates the rule even though it continues to appear in the list
until deleted. Unused rules at the end of the list always show
None
as the mapped register format.
Name: The name is optional and only used for display purposes.
Custom Registers Enabled: The Custom Registers Enabled parameter controls how many maps
are enabled and displayed.
Scale Factor and Offset: Optional fields, the Scale Factor and Offset value work together to
convert register data. The source data is multiplied by the scale factor and added to the offset to
produce the data in the mapped server register.
Swapping: By default, double registers in the DX80 are “big endian;” the most significant bytes are
in the first register and least significant bytes are in the second register. If remote clients accessing
this server at this IP address expect “little endian,” select the Swap Double Registers checkbox.
Modbus protocol by definition is “big endian” within each register, but the “endian” order of the
registers for 32-bit values is less standardized.
Zero Fill: Normally an attempt to read an undefined register returns an exception (error) code.
To enable reading of large data packets without nuisance errors, zero filling null registers so that
reading an undefined register between valid defined registers returns zero data rather than an error.
Other Commands
Insert/Delete buttons: Clicking the Delete button removes the map number shown in the Showing
# 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.
