CHAPTER 8 - CFW-09 OPTIONS AND ACCESSORIES
The command bits are available to read and write and they have the same
functionofthelogic commandbits 0 to7 (basicvariable3), howevernorequiring
the use of the mask. The basic variable 3 write influences the status of these
bits.

Detailed Function
Description
This Item describes in details the functions that are available in the CFW-09
for the Modbus RTU communication. Please note the following during the
message preparation:
Values are always transmitted as hexadecimal values.
The address of one data, the data number and the value of the registers
are always represented through 16 bits. Thus these fields are transmitted
by using two bytes (high and low). To access the bits, and the form to
represent one bit depend on the used function.
The messages, both for enquiryand response, cannot be longer than 128
bytes.
The resolution of each parameter or basic variable is as described in item
8.13.3.2.
