How to communicate omron plc without OPC UA Protocol

Post by imhht1311 » Tue Mar 17, 2020 5:42 am

Hello!

I want to communicate between WinCC OA and Omron PLC like simens's S7 Driver, Rockwell's Ethernet/IP Driver

I know that Omron PLC use Omron FINS Ethernet Driver.

I want to know that how to communicate Omron's PLC directly without OPC UA communication protocol.

Hi,

That's actually quite straightforward answer: if you cannot use protocols from WInCC OA such OPC UA, then you have to get c/cpp communication stack from OMRON and build your own driver using WinCC OA API. If the stack is well built and you have good c++ knowledge as well as API training, it is doable.

More information: if you want to use FINS, you can have a look into following link:

https://github.com/lammertb/libfins

Otherwise I noticed that some OMRON support also EIP, which is part of WinCC OA available drivers. So it is depending of which model of OMRON you plan to use.

If you are interested in an Omron FINS driver, you should get in contact with your WinCC OA sales contact.
Especially if you are not interested in developing a driver and having to maintain it.
