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.
Is this program applicable to devices that do not support Modbus RTU communication?
Hello, can I connect 8 rs232 devices( checkweigher) with one RS232(CM1241) module?
You can connect up to 32 devices, I do believe.
