Hi guys, I have been asked to assess whether we could use WinCC-OA as a SCADA solution on a site with Modicon Quantum and Modicon Momentum PLCs, does anyone have any experience of interfacing these with WinCC-OA?? I have not come across these before and from what I can gather they may support Modbus TCP.
Any advice would be greatly appreciated.

Re: Modicon Quantum PLC and WinCC-OA
Hello,
when reading the specification for these PLCs I got the information that Modicon Momentum supports Modbus TCP/IP.
The Modicon Quantum series can be connected via Modbus plus TCP. If a connection with the WinCC OA modbus driver is possible we do not know.
Maybe you can get OPC-servers for theses components which then can communicate with the WinCC OA OPC client.

Re: Modicon Quantum PLC and WinCC-OA
Basically any plc, and especially the Modicon, should support Modbus. The diificulty with A modbus device is often this. In the plc i could setup some memory to represent for example a descriptive string.
The Modbus protocol however only supports bits and words and the driver will not support 'home made' data like a string. This means, younwould have to read N words, knowing that they represent a string, and would need scripting to turn them into the right variabele.
I'd advise you to first look atbthe nature of the data. When it is just bits and words, then Modbus should work. When more complex.... Thrn you might face a challenge.
Good luck

Re: Modicon Quantum PLC and WinCC-OA
Modbus should be native to those PLC's and Modbus is supported by WinCC OA
I've done a project with WinCC OA + Quantum last year, worked with no problem

Thanks guys that's great, we are only assessing whether it is possible at the moment so this is really helpful

Re: Modicon Quantum PLC and WinCC-OA
It is possible to connect Quantum PLCs with Modbus TCP and works great. We have many projects with Quantum, Premium and M340 PLCs, but Momentum we haven't tried yet.
I think we have used over 30 or 40 Quantum PLCs with WinCC OA, with no problems whatsoever.
Just check that you have an Ethernet port on the PLC
