Re: [foxboro] FBM230 Communication with AB PLC5 over DH+

Dear Sir,
I have received the same problem, kindly confirm that integer register
address is correct. In our case we have address like N100:0 (16Bit Unsigned
Integer for digital).
Check the PLC data addressing format.

Thanks and Best Regards,
Imran Waheed Butt
