Artem,
I Think the openhpid running on EMERSON CO31KX is an old version that used to
listen on UDP port 4743 as opposed to TCP port 4743.
You may need to contact Emerson for an update in case you do not have the
privileges/access to change the openhpid files yourself.
You may try experimenting with the latest openhpi client code (it uses
sstreamsock object to open a TCP client socket these days) to make it
communicate over UDP, but I am not sure if that will work eventually, given
that the marshal/unmarshal code might have been changed radically between the
Emerson openhpid version and the latest openhpi client version.
Regards,
Pradip

Anton,
(1) HPI Daemon/Client have switched to libohTCPconnx.so from libohUDPconnx.so
in 2004. Since then, we have not used or tested with libohUDPconnx.so
functions. The way it is now, to use libohUDPconnx.so functions you would need
to change the source code.
(2) HPI Daemon/Client communication port, default port number 4743, can be
changed as described in openhpi/README.daemon.
Peter,

Re: [Openhpi-devel] udp and tcp ports
Hello!
"make all" builds libohTCPconnx.so and libohUDPconnx.so libraries from
sources in marshal directory.
However, I've found no option to use libohUDPconnx.so.
May be it is rudiment library from the past?
