   ### What happened?
   
   I think that something is not working with the TAG Creation...
   
   I cant build a tag to read data from slave-id 2 in modbus.
   
   I have a network with 10 slave, i need to read them in order but the string 
won't build
   
   When i remove the "{unit-id 2}" from the tag it works.
   
   ```java
   //connection
   plcConn = 
plcDM.getConnectionManager().getConnection("modbus-rtu:tcp://127.0.0.1:502"); 
//FIXME: Somente para debug
   
   // ...Doing things...
   
   builder.addTagAddress("holding-registers", "holding-register:1[23]{unit-id: 
2}");
   
   PlcReadRequest readRequest = builder.build();
   
   PlcReadResponse response = readRequest.execute().get();
   ```
   
   the error:
   
   ```
   Exception in thread "Thread-2"
