Hey Cesar,
I modified my code to use CachedPlcConnectionManager but the problem
persists: the program gets stuck on the getConnection call.
This is my code now:
public static void main(String[] args) {
// System.setProperty(SimpleLogger.DEFAULT_LOG_LEVEL_KEY, "Error");
Logger logger = LoggerFactory.getLogger(TestConnection.class);
String connectionString = "s7://10.10.26.88?controller-type:S7_300";
PlcConnection plcConnection = null;
try {
CachedPlcConnectionManager connectionManager = CachedPlcConnectionManager.
getBuilder(new DefaultPlcDriverManager()).build();
plcConnection = connectionManager.getConnection(connectionString);
if (!plcConnection.getMetadata().isReadSupported()) {
logger.error("This connection doesn't support reading.");
return;
}
System.out.println("Success");
} catch (Exception e) {
e.printStackTrace();
} finally {
if (plcConnection != null) {
try {
plcConnection.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
The exception trace is:
