DID YOU INSTALL SQL SERVER FIRST?

WinCC 6.0 don't support to connect directly S7 224 with PC. If you want, you can use OPC from SimaticNet or KepServerEx. Good luck!!

I just used PLC S7 300 to connect with VLT5000 by profibus, but MELSEC didn't. You have to download GSD file on www.danfoss.com.

what kind of PLC are u using ????

You can't create Scroll in a Picture of WinCC.If your application is large, you can create many Picture and create connection among them by buttons/images.. and codes .

Everyone can tell me how to tranfer program to serie GE 90 - 30. Thank you very much!!! I have to need adapter or not.

My PLC has a port 15pin on CPU. So, i can use your connection. Thank you!!!

I have tried many times to use real number but i wasn't successful. If anyone know to use it , please tell me!!!!!!!!!!! Thanks for your helps.

i recommend you install physical connection and set up parameter carefully . i hope you will be successful

there are also MX4 Scada , Labview , Lookout

If you have KepServerEX software , you can program HMI/Scada for most of common PLCs

you want to have free software. its impossible

hi , tomchubb ! Before , you should check physical connection from WeighScale to S7 by profibus. I believe that it have LED to show your connection is correct . Then, you set up hardware and parameters correctly . I believe you'll be successful. You must add GSD file into Step 7.

hi, everybody! i proposed this topic with the purpose that using real number on PLC is possible or not. Before, i had made " Automatic Weighing System " . I read analog signal from loadcell , converted into digital and operated caculation on integer. So , when spending caculating many times , error is larger and larger. Therfore , i wanted to use real number to able to reduce error in caculating process.

PG 2000 is used to edit program S5 or S7 , it is easy to use because it is able to install on windows.

I tried to program on Step 7 5.3 , but when i monitored , it didn't show desired value ( correct number ). I just used simulator to monitor . I entered input value from M register , then convert it to real number ( used function Integer number to Float number).

For example , i wanted to use sqrt( ) function to calculate in my algorithm. So , this function require to operate on real number

I have KepServerEx 4.0 ( full diver for every common PLC ) but i don't have any software SCADA. So, i can use visual basic to program SCADA , can't i ? As if anyone know how to do that, please tell me . Thanks to your helps.

you know, when installing Citect software , it will provide manual to use it.You check again .

Thank you so much! I will try to get it.

If you want to use DLLs , you must know name of functions in DLLs .But i don't know them.

I think i have OPC Foundation when installing KepServerEx but i don't have Library VB or VC++ to use function in DLL componnent. So, if you have , can you give me a copy ?

In my opinion , there is not neccessary to open Scada Porogramming Forum.This web site can answers any question about SCADA in Automation field. In addition to, many people have known this website for a long time. So, solved problems are easy when having many members. Our final purpose is only solving the difficults in Automated Working. This is only my idea!

You try to find PG 2000 software . It's easy to programand edit Simatic S5 on Windows.

what Jes said are completely correct. You can MPI to connect Pannel with PC or PLC but Inverter can't. You can use Profibus to connect Inverter with PLC siemens. However, you need to look for dirver of Inverter.Hope you to be successed.
