One of them dies with a high data level processing, but it doesn't generate a core dump.
How can I get this core dump to analize the process??
Thanks.. Daniel P.

Re: TCP Reset connection
I have made a snoop of my socket connection, and I have checked the Identification number of the IP level.
While the ID number in the server is increased one by one, the ID number in the remote controlled station is increased in a random number, usually 300 or 400...

Re: TCP Reset connection
When the EOF character is received then the read function returns cero.
I have programmed it this way:
bytesRead = read( clisock, buffer, BUF_SIZE);
if (bytesRead > 0){
/*Se han leído datos*/
}
else {
/* Tanto si es cero o menos uno, cerramos el
socket*/
}
If i...
Re: TCP Reset connection
Thanks,
I could find the reason of this Reset message sent by the controlled station.
It is caused by the sent of the OEF character inside the telecontrol protocol.
Now, How could I solve this problem?
TCP would have to ignore this EOF character.
Thanks.

Hi,
I'm going to use SOE module with 1ms of input resolution in my project.
I don't know If I need to include in each PLC system a GPS to convert the CST tiem to the UCT time format.
Could I use another time reference that not be the GPS time master, i.e. the PLC master time?

The GPRS clients must communicate under IEC 60870-5-104 protocol.
I have an Allen Bradley PLc, which sends data to a IEC 104 Interface module, which has to send the data to a GPRS gateway.
Which GPRS gateway must I use?
