Hi,
The problem is that the protocol used by the Huanyang HY02D223B is not Modbus
compliant. As I believe it, the implementers of the Modbus software in the VFD
have not understood the Modbus spec, and incorrectly implemented. it.

You plug the sprue (entry) going to the mold cavity with a thin sheet
of metal (that is melted once the molten metal reaches it), and put
the chemical on top. The slag melts to the top and the

Unless you know your card adapter can handle UDMA, disable it. Not all
card adapters are wired for UDMA and you get all sorts of problems if
you try to use UDMA on them. As far as I know all SATA CF card adapters
can handle UDMA. It may give you a bit more

Thanks for the hint. Currently getting 6.06 and 7.10

They are kind of slow. Not too bad to read, but still can be a couple
megabytes a second, depending a lot on the adaptor. But, the write speed
can be REALLY slow, vastly slower than a normal hard drive.

I'm not sure if this is relevant with Linux, but we have some Siemens
MicroBox PLC's at work, they run Windows XP embedded IIRC. They have a

to read/write constantly as virtual memory and wear the CF cards out
