Hi guys
I'm having some weird data conversion issue over modbus happening. And I found a post here before that is similar to what I'm seeing but no solution was found. http://www.plctalk.net/qanda/archive/index.php/t-76329.html
I have a GE Quickpanel talking to a Schneider M340. Booleans are transmitting properly. The problem comes up when I'm moving DINT and LREAL back and forth.
A value of 1(1.0) in the PLC comes in as 16256 on the HMI.
2(2.0) = 16384
3(3.0) = 16448
10(10.0) = 16672
I've seen mention online about Double Word, but I don't believe you can address double word in the M340?
Anybody have any ideas?
Thanks,
