Thanks Mr Rodney & Mr Crossbow for replying I checked the port and  They both ( software & device manager) use the same port (in my case port 3 ) And now the error is " communications timeout.check the port number, network address,baud rate,and the attached cable" when I select "search all baud rates" But if I didn't I get the same error " you must use the (RS232/usb)"

The driver of the cable is usb serial CH340 "in device manager" And it's been installed from a cd came with the cable

Thank you for replying The cable I'm using suppose to be used with s7 - 200 series as written "usb2.0 to RS485 for S7-200PLC series"

I have Chinese machine which has 226CN cpu I'm trying to communicate with it to upload the current program and maybe modify it. But I can't communicate with it  I'm using Chinese cable rs 232 to usb and windows xp. When I use it I get "you must use rs232/usb PPI multi master" massage  Is there a problem with the cable or the software? I tried to change language of the software to Chinese ( as a solution I found on the internet)but it doesn't help What should I do?        

Thanks mr crossbow for your reply. Gx developer doesn't have A0J2 it has only A0J2h I need software has A0J2 type

Thank you Mr Rodney, my plc output is 25pin port and I have an old PC has 9pin female and other 9pin male ports  so I bought a 25 to 9 pin female cable I used it to communicate the plc but I get the same error  Attached photo of plc port & the cable I'm using. Sorry If I didn't understand you well  

Hi Mr.PLC Members, I have Mitsubishi FX16MT unit, I'm trying to transfer programs to it using melsec medoc version 1.64b but I can't  I'm receiving error "no reply from PLC system",I'm using 25 pin to 9 pin cable and I tried also to connect it with usb to serial cable but the same error appeared  my setup: PLC system        FX Bit rate                 300 word length          7 parity                    Even stopbits                 2 "windows XP" Attached are photo of my unit with my cables and the error of the program  

Thanks gtsuport.

Hi All, I am looking for a way to program the unit using the programming console, but there are two of them: Horizontal: 3G2A6-PRO15-E Portable: C200H-PRO27-E What is the difference between the two programming devices? Attached is a part of the C200H-PRO27-E portable manual. A note from the manual indicates that "The programming console connot be used to create programs with more than one cyclic task. Use the CX-Programmer if more than one cyclic task is required.", what does one cyclic task mean? Does it mean that it needs a start button/switch to keep re-executing the program? Can I program an entire program using the programming console 3G2A6-PRO15-E? Or will I face the same limitation?

I am looking for a way to program the unit, but not yet sure what is the best way to do this.

Hi Michael, Thank you for your reply. I am asking about a direct way to connect and program the C40P using a computer as I don't have the needed hardware (the programming unit or the cables). I didn't find an answer to this question in the form.
