Hi Oles,

welcome on our friendly project list :-)

I am happy that your problem is a quite simple one. 
You are using "WORD" as a datatype. We tried to keep things close to this spec:
https://en.wikipedia.org/wiki/IEC_61131-3 which most PLC vendors seem to 
respect.

Here you can see that "WORD" and "DWORD" are considered Bit-Strings (Sequences 
of Boolean values)

If you want your values to be interpreted as integer values, use the integer 
types in your addresses instead:

WORD --> INT / UINT
DWORD -->  DINT / UDINT

That should be all.

    Hi PLC4X team)
    Could you help me?)
    When I try read data from plc s7_300 (Vipa), I see this ->
    [0, 0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0] - This must be 5
    How I can get 5 ?)
    
    My code:
    {
    String connectionString = "s7://192.168.0.5/0/2";
    
            try (PlcConnection plcConnection = new
    PlcDriverManager().getConnection(connectionString)) {
    
                PlcReadRequest.Builder builder =
    plcConnection.readRequestBuilder();
                builder.addItem("value-1", "%IW14:WORD");
                builder.addItem("value-2", "%IW12:WORD");
                builder.addItem("value-3", "%IW14:WORD");
                builder.addItem("value-4", "%IW16:WORD");
    
                builder.addItem("value-6", "%MD272:DWORD");
                builder.addItem("value-7", "%MD276:DWORD");
                builder.addItem("value-8", "%MD284:DWORD");
    
                PlcReadRequest readRequest = builder.build();
    
                PlcReadResponse response = readRequest.execute().get();
    
                ArrayList a = new ArrayList();
                for (String fieldName : response.getFieldNames()) {
                    if(response.getResponseCode(fieldName) ==
    PlcResponseCode.OK) {
    
                        System.out.println("SECONR IF->>>>"+fieldName+"->>>>"+
    response.getField(fieldName));
                        System.out.println("SECONR IF->>>>"+fieldName+"->>>>"+
    response.getAllIntegers(fieldName));
                        System.out.println("SECONR IF->>>>"+fieldName+"->>>>"+
    response.getObject(fieldName));
                        System.out.println("SECONR IF->>>>"+fieldName+"->>>>"+
    response.getAllBytes(fieldName));
                        System.out.println("SECONR IF->>>>"+fieldName+"->>>>"+
    response.getRequest());
                        System.out.println("SECONR IF->>>>"+fieldName+"->>>>"+
    response.getResponseCode(fieldName));
                        System.out.println("SECONR IF->>>>"+fieldName+"->>>>"+
    response.getNumberOfValues(fieldName));
                    }
    
                }
    
            } catch (InterruptedException ex) {
                ex.printStackTrace();
            } catch (ExecutionException ex) {
                ex.printStackTrace();
            } catch (PlcConnectionException e) {
                e.printStackTrace();
            } catch (Exception e) {
                e.printStackTrace();
            }
    }
