I have installed the PI ICU and PI Interface for RDBMS on a IPC.
I have created an ODBC Data Source to a SQL table, running on the HMI of my machine and the connection to the database is running well.
Then I created an interface node from the RDBMSPI.bat_new file and configured it.
My host is 172.26.1.12 and the used port is 5450.
If I run the telnet command, it is working.
But if I run the batchfile of the interface, it stops after trying to connect to the PI Server:
"RDBMSPI RDBMSPI1 1 0> Error  connecting to PI Server
 Connection to server lost
piut_setservernode failed for host = '172.26.1.12:5450'"
I have attached screenshots of the ICU to this post.
Does anybody know, what reason can cause this problem?
Best regards and thank you in advance,
