UDP
Byte Command
Parameters
Notes
FC
Set IP Address
First 8 bytes must
be set to the string
IP-SETUP (Hex 49
50 2D 53 45 54 55
50).
Next 2 bytes have
to be set to 00.
Next 2 bytes must
contain the serial
number.
Next 4 bytes have
to be the new IP
address.
This block can be sent as a broadcast,
because the serial number is unique. It
provides one method to set the IP address
of the Device Server if is on the local
network and the serial number is known.
Remember, broadcasts are only ‘heard’ on
the subnet on which they are generated. No
reply is sent by the Device Server, which
restarts using the new IP address after the
block is received.
Example (all in Hex):
49 50 2D 63 45 54 55 50 00 00 2A 12 81
00 01 02
IP address of the node with serial number
42-18 set to 129.0.1.2
FD
Set
Configuration
and IP Address
Same as FA, but
changes IP address
as well (bytes 0-3).
