RTU Write Map

The RTU Write Map page creates a map entry that writes data to one or more remote Modbus RTU
serial devices.
Maps on the RTU Write Map page only write data from the local register to the remote register
listed. Use the RTU Read Map page to read data from those remote devices.
Any parameters shown may be changed and submitted by clicking the Update button, but this
screen displays only an abbreviated list of the map parameters. To view and/or modify the complete
set of parameters, click on the hyperlinked map number in the left column and use the expanded
RTU Write Map page.
For each local register, enter the register number, scale, remote type, remote register format,
remote register number, and remote unit number (device).
Local Register: The data in the local register is multiplied by the scale factor, then written to the
remote register.
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 written to in the map.
Remote Type: Select a type from the following drop-down list: none, coil (output), discrete input,
input register, or holding register.
Remote Type
Coil (output)
Discrete Input
Input Register
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 are used.
Selecting None for remote type negates the rule though it remains in the list until deleted. Unused
rules at the end of the list always show None as the remote type. To prevent these from displaying,
reduce the number of maps enabled on the expanded view screen.
Remote Slave ID (Unit #): The Remote Unit number is the slave ID of the remote unit to be written
to.
Scale: The raw data in the local register is multiplied by the scale factor to produce the data written
to the remote register.
Swapped: Check the Swapped box to swap the byte orientation.
