Hi there,

I am having difficulties integrating a Omron PLC to my project.

I want the tags from the Omron-PLC (16 bit) to be read out on a Simatic HMI, which is controlled by a Siemens 300 PLC (8 bit).

Which gateway do I need for this project, and how do I set it up?

 in advance!

Do you have TIA software?

Whether the OMRON PLC communication is through RS 422?

Are you using comfort panel? 

More details might help understand your case better.

Thanks,

Jay

The communication is through RS232, and the panel is a Siemens comfort panel.

On the panel, I want a screen to chose between screens that get tags from the Siemens-PLC, and a screen that gets tags from the Omron-PLC.

There is a serial port available in HMI comfort. But I ain't sure whether you can directly connect the RS232 to that or you need to use a converter for RS232 to Rs422 and then connect to that port. After that it is just about TIA portal software. You need the existing project backup, then modify the connections for Omron PLC and testing. IT is what I think. Just wait for further inputs regarding this from experts. Already the SIMATIC HMI have Omron comm driver, so there won't be much difficulty, Just need to define tags with correct address from Omron PLC documentation.

Thanks,

Jay

Would it be possible to connect the two PLC's in Devices & Networks in the Tia-program, and then in some way migrate the Omron-tags to the HMI?

Next challenge would then be the tags being 16 bit boolean on the Omron PLC, but the Siemens only got 8 bit boolean, unless you make an array in a datablock? Could this be a solution?

Omron PLC supports Profibus? If yes then it might be possible to integrate in TIA. Maybe you need GSD file of Omron PLC and import to TIA. These are all just my thoughts, I never worked on Omron PLC and Profibus  and HMI. 

Thanks,

Is this overview helping understand my question?

I have found a gateway, but I am uncertain, wether this will work in practice?

The gateway i am thinking of buying is "

Gateway PROFIBUS, RS-232, RS-485 Wachendorff HD67561 24 V/DC" from Here.

Sorry, regarding the gateway I ain't sure. But for S7-300 no GSD required. Only for third party PLC, GSD is required I think. If you don't want communication between PLC, maybe GSD is not required for HMI configuration. Just the connection with HMI is enough. These are all my thoughts, dontd just blindly accept my inputs. Think of it and see if someone else here has thoughts about it. I can be wrong as well.

Thanks,

Thank you very much for your response, Jay.

Maybe this overview helps understand the HMI-part further.

If that gateway is not that expensive, consider getting one. Then just try to start with TIA software and start with mapping. Hope you are not new to TIA software.

Thanks,

Jay
