Hello,

Can dear expert help in attached example why I could not read via MODBUS the actual weight from the load cell indicator, I tried like this example with Schnieder PM800 it's work perfect, but when I tried with load cell indicator SI 580 E it's not work.

I'm using CPU 224XP

Thanks.

Hello,

I recommend check functionality of device with some PC MB RTU Master SW connected via suitable adapter to Weigh device. I expect you know exact comm settings on device and also registers addresses, data format to correctly receive data. Check for first that functionality of MB RTU with PC app and then you can better continue or find problems.

Dear DURIS_I,

Thank you for response, I tried by ModScan 32 software, I found that I have assigned to DataPtr (&VB100), when I checked in status chart I checked vb100 and vb101, so because the count was 2 words the value was in vb 102 the I extend status chart from vb100 to vb103 I found the current weight, now it's Ok .

Thanks.

Hello,
