What about plc.Read("M9.2")? I have my doubts looking at the code for converting the resulting data to bool, but this should be the way to read. As for writing, plc.Write("M9.2", true) should be enough, however I won't make any promises that it actually works.

I don't have a PLC to test this against and I have never used memory bits, but the above should get you going.

Yes, after I write this way, it's invalid
