I have the communication working between the PLC and my C app now. I imagine now that there is more to do than what the statement I have quoted led me to believe. This is just my first attempt at communicating via the serial port. Mewtocol performs the following: Mewtoxol 14th, The documentation I have states ocm PLC answers automatically to commands received from the computer, so no program is necessary on the PLC side in order to carry out communication.

I will download and try the demo tomorrow morning. In this case this frame has been created for a Panasonic PLC but with the skill 2 serial converters and the device in question and the documentation can generate the communication frame for any brand device either PLC or HMI.

The function only allows writing in registers.

Input parameters String Variable to concatenate int size or number of zeros maximum to add. These PLCs are very practical and a high percentage of machines have it as a unit control. All times are GMT I loved the PeakHMI tools! October 24th, To read registers a new frame must be created that requests data from a specific register and the PLC will send the answer that must be interpreted in arduino.
The time now is April 8th, We take the whole frame, and with the getBytes function we move it to a byte array and mewtovol for loop makes an exclusive or with the records mewtpcol the BCC result we convert it to String and concatenate it to the end of the frame, if the BCC is Wrong ,ewtocol panasonic PLC will discard the frame automatically. I will be proceeding to investigate this issue for now believing that the PLC does respond, as for other programs I've used it for work just fine.

The Mewtocol protocol has similarities to Modbus, although the Mewtocol mixes Hexadecimal and Ascii in its frames, with 2 usb serial converters, 1 PLC and a panasonic screen, I take the task of spying physically the plot, understand it and replicate it in Arduino IDE. newtocol
