Disabled 1–127, excluding 111 (111 is reserved to the service port)
Enabled 1–15, 32–47, 64–79, and 96–110
2. Set Modbus Address to a unique value on the network.
3. Set
Floating-Point Byte Order
to match the byte order used by your Modbus host.
Code Byte order
0 1–2 3–4
1 3–4 1–2
2 2–1 4–3
3 4–3 2–1
See the following table for the bit structure of bytes 1, 2, 3, and 4.
Bit structure of floating-point bytes Table 6-10:
Byte Bits Definition
1 SEEEEEEE S=Sign
E=Exponent
2 EMMMMMMM E=Exponent
M=Mantissa
3 MMMMMMMM M=Mantissa
4 MMMMMMMM M=Mantissa
4. (Optional) Set Additional Communications Response Delay in delay units .
A delay unit is 2/3 of the time required to transmit one character, as calculated for
the port currently in use and the character transmission parameters.
Additional Communications Response Delay is used to synchronize Modbus
communications with hosts that operate at a slower speed than the device. The
value specified here will be added to each response the device sends to the host. The
default value is 0. Valid values range from 1 to 255.
Tip
Do not set
Additional Communications Response Delay
unless required by your Modbus host.
