Hello César José García León,
thank you for looking into the problem and responding.
We have three real S7 PLCs in our test lab:: S7-1200, S7-1515, S7-1516
For testing purposes, I connect to the PLC via an SSH tunnel, but I also run
the code without an SSH connection next to the PLC. I have improved my code and
logging a little bit to show you more details. I have tried out the connection
with all three SPS via SSH and next to the SPS on a remote computer. Everything
runs perfectly in version 0.11.0 but if I change the version to 0.12.0 the
exception occurs as described before. You can find more details in the log
output below.
Here is my current test code:
```
import org.apache.plc4x.java.api.PlcConnection;
import org.apache.plc4x.java.api.PlcDriverManager;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class TestConnectionWithPLC4X2 {
private static final Logger logger =
LoggerFactory.getLogger(TestConnectionWithPLC4X2.class);
public static void main(String[] args) throws Exception {
String urlS71515 = "s7://192.168.0.111:102?remote-rack:0&remote-slot:1";
// S7-1515 (Lab)
String urlS71200 = "s7://192.168.0.190:102?remote-rack:0&remote-slot:1";
// S7-1200 (Error_FBs)
String urlS71516 = "s7://192.168.0.186:102?remote-rack:0&remote-slot:1";
// S7-1516 (Simulation)
String executionEnvironment = System.getenv("EXEC_ENVIRONMENT");
if ("local".equals(executionEnvironment)) {
urlS71515 = "s7://127.0.0.1:1515?remote-rack:0&remote-slot:1"; //
S7-1515 (Lab)
urlS71200 = "s7://127.0.0.1:1200?remote-rack:0&remote-slot:1"; //
S7-1200 (Error_FBs)
urlS71516 = "s7://127.0.0.1:1516?remote-rack:0&remote-slot:1"; //
S7-1516 (Simulation)
}
logger.info("");
logger.info("#####################################################################");
logger.info("Test connection with S7-1515");
logger.info("#####################################################################");
try (PlcConnection connection =
PlcDriverManager.getDefault().getConnectionManager().getConnection(urlS71515)) {
logger.info("Connection status with S7-1515: {}",
connection.isConnected() ? "CONNECTED" : "DISCONNECTED");
}
logger.info("Connection Closed");
logger.info("");
logger.info("#####################################################################");
logger.info("Test connection with S7-1200");
logger.info("#####################################################################");
try (PlcConnection connection =
PlcDriverManager.getDefault().getConnectionManager().getConnection(urlS71200)) {
logger.info("Connection status with S7-1200: {}",
connection.isConnected() ? "CONNECTED" : "DISCONNECTED");
}
logger.info("Connection Closed");
logger.info("");
logger.info("#####################################################################");
logger.info("Test connection with S7-1516");
logger.info("#####################################################################");
try (PlcConnection connection =
PlcDriverManager.getDefault().getConnectionManager().getConnection(urlS71516)) {
logger.info("Connection status with S7-1516: {}",
connection.isConnected() ? "CONNECTED" : "DISCONNECTED");
}
logger.info("Connection Closed");
}
}
```
Log output with version 0.11.0 => works and looks good
```
