CFW-08 OPTIONS AND ACCESSORIES
Bit Number
Bit 3
Bit 4
Bit 5
Bit 6
Bit 7
Status Bits
Function
0 = JOG inactive
1 = JOG active
0 = Local Mode
1 = Remote Mode
0 = No undervoltage
1 = With undervoltage
Not used
0 = No fault
1 = With fault
The command bits are available to read and write and they have the same
function of the logic command bits 0 to 7 (basic variable 3), however no
requiring the use of the mask. The basic variable 3 write influences the
status of these bits.

8.20.3 Detailed Function
Description
This section describes in details the functions that are available in the
CFW-08 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 enquiry and response, cannot be longer than
128 bytes.
The resolution of each parameter or basic variable is as described in
item 8.19.3.2.
