Re: Writing Continuous Modbus Registers

Adam, Ah, sneaky! :) I started looking at all the driver logic and got a bit dizzy ... :) Excellent, thank you for the feedback, I will give this a try now!! Question, the driver code you mentioned, does this read and write all (8) modbus registers at the same time? If so, what do I need to do to im...

Re: Writing Continuous Modbus Registers

Adam, Thank you for the code snippet. At this point I think mine is working well enough to not need a complete driver. But I am missing the details on the fundamental ability to copy from one variable format to another; -> How do you copy a BYTE variable to any location within an INT16 variable? -> ...

The trick is, I need to be able to write all (8) INT16 modbus registers at once (within the same modbus packet). The device requires all (8) r...
