I downloaded the Siemens version, but I have problems, I set up the PLC settings correctly and try the sample design. such as start - stop. I pressed F5 and a dialog box appear says "Couldn't open Serial Port COM2 , Check COM Port and Baud Rate "
I already turn my s7-200 PLC into RUN mode. error still occur.
any ideas or solutions?
Thanks for the quick response.
The bit you need to be looking at is "Couldn't open Serial Port COM2 , Check COM Port and Baud Rate ". Which COM Port is the PC/PLC interface connected to? If you are not sure then somehow you need to get to the Device Manager on your computer. I can say exactly how because it depends on your version of Windows. One way is to open a Command Prompt (Start/All Programs/Accessories/Command Prompt) and type (or copy and paste) C:\Windows\System32\devmgmt.msc Once there go to Ports and see which communication ports you have available. Make sure that it matches the Port set in the project. Then have a look at the Baud rate set in the project and make sure it matches what is set on the PC/PLC cable.
The COM port is not to do with the PLC it is to do with the PC that you are using. Please go to the Device Manager as described above and then tell us which COM port you are using on the PC.
So straight away you can see that you have Advanced HMI set to use COM2 but your computer only has COM1. So set Advanced HMI to use COM1 and things might start working.
As it is an S7-200 I would expect you would be connecting to Port 0 on the PLC.
