Modbus RTU Setup Submenu
The
Modbus RTU Setup
submenu contains the read and write map screens for setting up the
Modbus RTU Slave option. The two screens contained within the
Modbus RTU Setup
tab apply
only to the Ethernet processor on the Gateway Pro or a DX83 device.
RTU Read Map
The
RTU Read Map
screen creates a map entry to read data from one or more remote Modbus
RTU serial devices. Click on the map number in the left column to view more detail and to insert or
delete maps.
Maps entered on the
RTU Read Map
page only read data from remote devices into local registers.
To write data to those remote devices, go to the
RTU Write Map
tab.
This screen displays an abbreviated list of maps. Any parameter shown may be changed. To view
and/or modify the complete set of parameters, click on the map number shown in the left column
and use the expanded
RTU Read Map
page. To submit changes, click the Update button.
For each remote register to be read, enter the register type, remote register format, register number,
remote unit number, and local register number.
Local Register Number; After the remote register is read and the data multiplied by the scale
factor, the data is written to the Local Register number.
Name: The name is optional and used only for display purposes. The name acts as an identifier for
a specific register map. Type in the name in this screen.
Remote Register Format: Select the format of the remote register from integer, unsigned, double,
float, or bit. An integer is a 16-bit (signed) number, an unsigned format is a 16-bit unsigned number,
a 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.)
Remote Register Number: The Remote Register entry is the register being read.
Remote Type: Select a type from the following drop-down list: none, coil (output), discrete input,
input register, or holding register.
Banner Engineering’s SureCross™ slave devices use only input registers and holding registers.
When using slave devices from other manufacturers, please refer to the manufacturer’s
documentation to determine what I/O types they use.
