There are some OPC for IEC. I just found that one in google. Maybe you should look for a solution like that. Or maybe you could use a IEC - Profibus gateway, like this.

Hi Maxim, Dainelle is right! You are able to get a number of software which converts IEC<>OPC. But I would like to find out from you, in IEC101 protocol, the communication media should be serial cables (RS232/422/485), how are you going to interface it with the PC which you are running WinCC? Is your controller (IEC101Master) is a field device? If yes, your WinCC should ideally be IEC101Master which enquires information from Slave. Let me know if I've misunderstand your situation... cheers kee

I don't know which devices are in the IEC network, but WinCC (meaning the OPC Server WinCC communicates with) should indeed probably be the master, and request the information from the other devices. We have applications with modbus RTU indicator devices, connected to a proprietary "supervisory" system. In this case the serial port from the computer was used. I've also worked on a project where an S7-200 was used to convert the modbus info into ethernet for the S7-300's and S7-400's in the network. RS485 links are much used in industrial process control where reliability is important. Also,the ability to communicate over a long distance at a high speed is important when it comes to industrial plants where the stations might be spread over a large area.It is very common to have a PC in charge of controlling a given process. PC's in general have an RS232 serial port (COM port) and therefore there are two solutions to link the computer to an RS485 network: One is to plug an RS485 interface in a computer slot and the other is to convert the RS232 level signal coming out the computer serial port into an RS485 signal. For that you'd need a RS232/RS485 converter.
