2.2 Modbus Functions
The controller supports the Modbusrfunctions listed in
Figure 2-1.
2.3 Modbus Protocol Tables
The tables in Section 2.4 document the controller
information available using the Modbusrprotocol.
In the following tables all word (16-bit) expressions are
integers unless otherwise noted and are shown in
decimal notation unless otherwise noted. Hexadecimal
expressions begin with 0x. Characters are in the
standard 8-bit ASCII character set. Unspecified bytes
are undefined, such as the high (most significant) byte of
holding registers that contain byte data in the low (least
significant) byte.
The tables include the following items.
Register. Modbusrregisters are 16-bit registers and
are numbered consecutively.
Data Description. The Data Description column
describes the information located at the address.
Access. The Access column shows the type of access
allowed to the register. RO is read only, WO is write only,
and RW is read and write.
Data Type. If multiple registers are used, the Type/Size
column shows the number of WORDS used, and the
Range/Units column provides a breakdown of the
information available within the parameter.
Range/Units. This column lists additional information
about the register type when applicable. For example, if
multiple WORDs are used, this column describes the
information stored in each WORD. It also lists the units
for measurements which have them, the range for valid
input or output when applicable, and the the scale factor
for some parameters. Bit 0 is the least significant bit and
bit 15 is the most significant.
Modbusr
Function Function Name Description
03 Read Holding Registers Reads a single register or a range of registers.
06 Preset Single Register Sets the value of a single register. Use this function to set all data occupying a single

WORD [0:15]. Represents a 16-bit word that may be
divided to contain several items. Bits 0 through 15 are
arranged right-to-left, with bit 0 on the right.
Example: Refer to register number 41320, the System
Start Date. Bits 0 through 4 contain the date of the
month, 0--31, represented in binary format. Bits 5
through 8 contain the month, 1--12. Bits 9--15 give the
year, starting with the year 2000 (number 0) and
extending through 2127 (number 127). For example,
the 10th of February, 2025, would be represented as
shown Figure 2-2.
Ranges and Bits. Some registers list a range of items
with a bit set for each item. Interpret the first number in
the range as corresponding to Bit 0 and the last number
in the range as corresponding to Bit 15.
