7.3.1  ENRON Floating Point Support 

Many manufacturers have implemented special support in their drivers for what is 
commonly called the Enron version of the Modbus protocol. In this 
implementation, addresses greater than 7000 are presumed to contain floating-
point values. The significance to this is that the count descriptor for a data 
transfer now denotes the number of floating-point values to transfer, instead of 
the number of words. 

 

7.3.2  Configuring the Floating Point Data Transfer 

A common question is how to handle floating-point data when using the module 
as a Modbus client. This really depends on the server device and how it 
addresses this application.  

Just because your application is reading or writing floating-point data, does not 
mean that you must configure the Float Flag, Float Start, and Float Offset 
parameters within the module.  

These parameters are only used to support what is typically referred to as Enron 
or Daniel Modbus, where one register address must have 32 bits, or one floating 
point value. Below is an example: 

Example #1 

Modbus Address 

Data Type 

Parameter 

47101 

32 bit REAL 

TEMP Pump #1 

47102 

32 bit REAL 

Pressure Pump #1 

47103 

32 bit REAL 

TEMP Pump #2 

47104 

32 bit REAL 

Pressure Pump #2 

With the module configured as a client, you only need to enable these 
parameters to support a write to this type of addressing (Modbus FC 6 or 16).  

If the server device uses addressing as shown in Example #2, then you do not 
need to do anything with the 

Float Flag

 or  

Float Start

 parameters, as this 

addressing scheme uses two Modbus addresses to represent each floating-point 
value: 

Example #2 

Modbus Address 

Data Type 

Parameter 

47101 

32 bit REAL 

TEMP Pump #1 

47103 

32 bit REAL 

Pressure Pump #1 

47105 

32 bit REAL 

TEMP Pump #2 

47107 

32 bit REAL 

Pressure Pump #2 

Because each 32 bit REAL value is represented by two Modbus addresses 
(example 47101 and 47102 represent TEMP Pump #1), then you do not need to 
set the 

Float Flag

, or 

Float Start

 for the module for Modbus FC 6 or 16 

commands being written to the server.
