Modbus Register Configuration
The factory default settings for the inputs, outputs, and device operations can be changed by the user through the device Modbus regis-
ters. To change parameters, the data radio network must be set to Modbus mode and the data radio must be assigned a valid Modbus
slave ID.
Generic input or output parameters are grouped together based on the device input or output number: input 1, input 2, output 1 etc.
Operation type specific parameters (discrete, counter, analog 4 to 20 mA) are grouped together based on the I/O type number: analog 1,
analog 2, counter 1, etc.
Not all inputs or outputs may be available for all models. To determine which specific I/O is available on your model, refer to the Modbus
Input/Output Register Maps listed in the device's data sheet.
For more information about registers, refer to the MultiHop Product Manual, Banner part number 151317.
40000s Standard Physical Inputs
Registers x0001 through x0016 are the results registers for inputs 1 through 16. For a list of the active results registers for your MultiHop
radio, refer to your product's data sheet.
40400s Extra Inputs
Registers x0401 through x0500 are the results registers for extra inputs 1 through 100. For a list of the active results registers for your
MultiHop radio, refer to your product's data sheet.
40500s Standard Physical Outputs
Registers x0501 through x0516 are the results registers for outputs 1 through 16. For a list of the active results registers for your Multi-
Hop radio, refer to your product's data sheet.
40900s Extra Outputs
Registers x0901 through x1000 are the results registers for extra outputs 1 through 100. For a list of the active results registers for your
MultiHop radio, refer to your product's data sheet.
41000s Input Parameters
Data radio inputs have the following generic parameters. These are not global parameters but are associated only with a particular input.
There are currently 16 separate inputs possible; the factory default settings are defined in the I/O specifications.
Parameters for Input 1 are at 41001 through 41008. Parameters for input 2 are at 41051 through 41058. Each following input is offset
from the previous one by 50 registers.
