Hello, can I connect 8 rs232 devices( checkweigher) with one RS232(CM1241) module?
This is just a fixed frame. It will not be correct in other cases. If the Slave continuously sends data, the next frame will be appended to the previous frame in your RS232 buffer.
send your problem to dadautomations@gmail.com , we can help you
