It seems this is still an issue. I created this little program:
`
package org.apache.plc4x.java.modbus;
import org.apache.plc4x.java.api.PlcConnection;
import org.apache.plc4x.java.api.PlcDriverManager;
import org.apache.plc4x.java.api.messages.PlcWriteRequest;
import org.apache.plc4x.java.api.messages.PlcWriteResponse;
import org.apache.plc4x.java.api.types.PlcResponseCode;
import org.apache.plc4x.java.spi.values.PlcDINT;
import org.apache.plc4x.java.spi.values.PlcREAL;
public class ManualTest {
public static void main(String[] args) throws Exception {
while (true) {
String connectionString = "modbus-tcp://192.168.23.30";
try (PlcConnection plcConnection =
PlcDriverManager.getDefault().getConnectionManager().getConnection(connectionString))
{
PlcWriteRequest.Builder builder =
plcConnection.writeRequestBuilder();
builder.addTagAddress("value-1","holding-register:14:DINT",new
PlcDINT(-242442424));
builder.addTagAddress("value-2","holding-register:26:REAL",new
PlcREAL(3.141593F));
PlcWriteRequest writeRequest = builder.build();
PlcWriteResponse response = writeRequest.execute().get();
for (String fieldName :
response.getTagNames()) {
if(response.getResponseCode(fieldName) ==
PlcResponseCode.OK) {
System.out.println("Value[" + fieldName + "]:
updated");
} else {
System.out.println("Error[" + fieldName + "]: " +
response.getResponseCode(fieldName).name());
}
}
System.out.println("done");
}
}
}
}
`
And I can see a constantly increasing number of open threads.
