UDP & TCP System Protocol
UDP System Protocol
If this communications protocol is selected, the master application must be
able to generate UDP communications network, to naturally include Modbus
communications network within the message. The communications port for
this type of communications is not critical and therefore the port number may
be left as the standard port given by the EDSetup software as a default
(10001).
An MSDOS (MBUS) program is on the Extras diskette. This will be able to test
and verify that the equipment is operating correctly by requesting the different
recordings via communications.
Example (Register of Voltage L1):
C:\>MBUS u172.16.50.1 p10001 c 010400000002
o 192.168.0.1 is entered, this is the device’s IP address.
o 10001 is the Local Port previously entered.
o 010400000002 is the Modbus Record (peripheral number 1, reading
function 4, initial recording 0 (hexadecimal) and two bytes are requested
(hexadecimal)).
o The variable c, means the continuous request from the network (to end,
click on Enter).
