ModbusRTU & Unitronics help needed

[Chad2017]

Hi All, I'm a newbie.  I'm just trying to display a readout from Unitronics Jazz. I've set it up very simple and followed the ADVHmi quickstart but get nothing.
I have tested PLC to pc connection using CAS Modbus Scanner and as you can see by the screenshots the values are there- the one i want to display is Reg Address 40003.
Hoping someone can offer some help.
Cheers

Do you have any other software online while trying to run AdvancedHMI? When using the serial port, AdvancedHMI needs exclusive access to the port, therefore no other software can be accessing the PLC.

[Chad2017]

No I have nothing else using the port at the same time, and I make sure I always shut down CasModbus Scanner software.  I have also tried on another pc a brand new laptop which only has Advancedhmi and visualcommunity on it and still no success.

Use a BasicLabel instead of the DigitalPanelMeter. It will give more feedback of problems.

[Archie]

Also you can set the EnableLogging property to true. This will create a log file in the bin\Debug directory that will give some feedback on what is happening.

[Chad2017]

Thanks I'll give those things a try.

[Chad2017]

Ok i've now tried using a "basic label" instead and still no readout.. 
Have set EnableLogging to True and the following is the Log from the bin\debug directory after a couple of tests. I'm not sure myself what to make of it?

UPDATE........... I just found this driver error log below,  i guess this is related to it not working but where do i start?

SendQueProcessor-Cannot access a disposed object.
Object name: 'ModbusRTU DLL is disposed'.
SendQueProcessor-Cannot access a disposed object.
Object name: 'ModbusRTU DLL is disposed'.

It seems that a response from your device is not being received. You may need to check the node address, baud rate, etc.

This is a breakdown of the packet being sent:

01 - Slave ID (Node address)
03 - Function code 3 (read holding register)
0002 - Register 2
0001 - Read 1 register

last 2 bytes are checksum

Ok , so i've spent hours last night and today trying every combination of coms settings in the plc and pc and still with no luck.
I have also tried another identical model plc unit and still no luck.  CAS Modbus Scanner on the PC reads the values fine so wouldnt that mean my connection and plc coms settings are ok?

[Archie]

Since you are not seeing any error on the BasicLabel, the only thing confirmed so far is that your serial port exists and opens without errors. It's showing behavior of not having a com setting correct, such as baud rate, data bits, stop bits, etc.

Use the patched version 3.99x and try to run your test again. This version will give more details in the log file.

Ok so still no luck after trying the patched version and various com settings as you can see below and no info showing up in the Basic Label.

What gets me is that I had this running fine after a few minutes setup on a windows 7 PC about 18months ago it was with an older version of Visual studio and obviously back then an older version of ADVHMI . I cant remember the versions though and no longer have that PC. I now only have windows 10 PC's.
Am still using the same PLC with the same rs232 to usb adapter.
Also want to thank you Archie for you help so far and quick responses.

[Archie]

What about the slave ID? Are you sure it's 2?

[Chad2017]

Yes, definitely 2 for slave id, and this is confirmed as set in the PLC and also works for CASmodbus scanner software.

[Archie]

So let's get it to mimic exactly what your Mobus scanner is sending:

- Add a BasicLabel and set PLCAddressValue tp 40001
- Add a 2nd BasicLabel and set PLCAddressValue to 40010
- On MosBusRTU1, use these settings :
PortName : COM3
BaudRate : 9600
DataBits : 8
Parity : None
StopBits  :One
StationAddress : 2
EnableLogging : True

Delete the existing driver log file, the run that and post what you get in the new driver log file
