6. Register Map for Process and Operation Type Variables
What’s in this section?
This section describes all parameters accessible by Function Code 03, 04, 06 and 10h. Section 6.1 gives a
global overview of each function and its addresses/registers. Sections 6.2 through 6.28 contain the details
on each function and each of its parameters.
Your particular controller may not contain all parameters shown. If you see a function that is not on your
controller, either it is not available for that controller model or it is not in your configuration.
6.1 Register Map Overview
Table 6-1 describes the global register map for Function Code 03, 04, 06 and 10h. Details on each address
are in sections 6.2 through 6.28.
Conversion between Address (Hex) Number and Register (Decimal) Number
To convert the address number to the register number, convert the address from hexidecimal to decimal
and add 1. Registers are addressed starting at zero: registers 1-16 are addressed as 0-15.
To convert the register number to the address number, subtract 1 from the register and convert to hex.
