Hi Neil, I have tried the latest program but it does not response to my PLC.

Hi Maintpro, What type of cable you are using? I have experienced that kind of problem before when i used my laptop to communicate to the FX2n plc. If you are using the RS485 port using the laptop, it is trully very hard to get the communication but if you are patient, just always press F3 or online comm. I tried to use my desktop and i found no problem. Since laptop is more convenient, i never use now the rs485. I currently use FX2n-232BD!! The problem is not related to your OS, it is in the port that I cant explain to you deeply.

Hi Neil, I know you are expert in VB programming. I have attached a a sample PLC program (FX2N) and its VB form together with Mitsubishi programming protocol format. I couldnt interpret it well and i hope you can help me on how to deal by providing me a simple example VB program. I used FX2N-232BD for communication. In my conditions: * When the Command1 button is clicked, the M0 of the PLC will be active and energizing the Y0 output of the PLC. * When the Command2 button is clicked, the M1 of the PLC will be active and de-energizing the Y0 output of the PLC. * The listbox will display "Y0 is ON" if Y0 is ative and "Y0 is OFF" if Y0 is inactive. The signal to listbox should be from the PLC. If the VB program could not receive any response from the PLC, MessageBox will display "Communication Error". sample_FX2N_prog___protocol.pdf

Hi Neil, had tried your "Comms" project and is working well... You did a great stuff!!! How about if I will have to control the M, what should I add to the "Case"? Regarding the other project, I don't know what shout I have to fill-up on the textbox field... but I tried putting a strings like "<STX>100A0020700<ETX>, "255" appears on the txtbox field.

Hi Calvin, Any update to my querry...

This is the extracted FX2N Communication manual which i have found from this net. I need your help to interpret this for me by giving a simple VB program base on my conditions above... FX2n_Communication.pdf

Hi Calvin, Thanks a lot but still doesnt work. I have attached a new conditions and i hope this would help now. I will also attached some pdf file which has the mitsubishi protocol format. I couldnt interpret it well and i hope you can help me on how to deal by providing me a simple example and i think i can do the rest. In my conditions: * When the Command1 button is clicked, the M0 of the PLC will be active and energizing the Y0 output of the PLC. * When the Command2 button is clicked, the M1 of the PLC will be active and de-energizing the Y0 output of the PLC. * The listbox will display "Y0 is ON" if Y0 is ative and "Y0 is OFF" if Y0 is inactive. The signal to listbox should be from the PLC. If the VB program could not receive any response from the PLC, MessageBox will display "Communication Error". Everyone in the net are also invited to help...

This is the response if the setting of the comm is "9600, 8, N, 1" if you select "PC" command:

hi Neil, I also tried to communicate this with my FX2N PLC via 232BD port, but same experience with Calvin "RCV: Unknown response from PLC".

Hi Calvin, I want to control the lamp either by the X0 and CommandButton. X0 is used in remote area, and the CommandButton is used in the Machine PC. I either of the X0 or CommandButton is active, the lamp will turn-ON.

Hi Neil, I had tried to open your PLC program but cannot be opened by my software (MELSEC Version40E). Anyway, I will try to test your VB code into my machine and will inform you later...

Hi Calvin and Mr panic mode, Can you help me on this base on the conditions above?
