Connecting CitectSCADA v7.2 to M340 through OFS

Dear All,

I've been struggling for a week to connect CitectSCADA v7.2 to M340 PLC through OFS and things aren't working out

Here's the setup:

I programmed a P34 2020 PLC with a simple ladder diagram using Unity Pro XL and I exported all variables (7 bool/ebool) with right-click on "Variable & FB instances" -> Export.
The PLC is connected to the PC through Ethernet.

Using OFS Configuration tool I made an Alias for the PLC, and then checked the OFS using the OFS Client, no errors was shown in the OFS diagnostic window and I could read and write on variables through the client. Tried this using STU and XVM files for alias.

In CitectSCADA, I did the following: New project -> new cluster -> new address (local 127.0.0.1) -> new IO server, used the local address -> Express Wizard and chose the following options: External I/O Device, OFSOPC, Address is Alias name, didn't check link, -> finish -> change address in Board to 1000 (same rate used in the OFS Client).

Then I built the project and started Computer Setup Wizard: Server and Control Client (didn't check Multi-Process), Stand alone, entered password.

Now I couldn't import tags (Tools > Import tags) no matter what options I choose, and if I run the project (I made a simple graphics page) here's the diagnostic window:

And of course the rectangles associated to tags are hashed.

Finally if I use MODBUS/TCP Ethernet with fastlinx in Express setup and put the PLC address, I was able to import tags but they wouldn't be read or written at run.

Any help is greatly appreciated! Thanks in advance

Any suggestion is appreciated!

In the io server network setup you must use the ip address (or name) of the citect pc (not 127.0.0.1 that is the local host address)

Thanks for your reply, unfortunately the problem wasn't solved.

Problem with M340/BMX AMO 0410

Dear All,
I'm new in PLC's and I have a problem with Modicon M340.I would like to attach analog output modul(BMX AMO 0410) to rack.So far so good.But when I open my Unity PRO XL 4.1. I can't find this modul(BMX AMO 0410) there is only BMX AMO 0210,I think.

Can you help me?
Thank

New module needs later version of UnityPro
Not sure if it is in v5 - current version is 6

Thank you GeoffC.Yesterday I installed Unity Pro XL 5.0 but I do not have time to check the result.Also I spoke with my colleague and he confirm the same.

Now I will try to make some modifications in the program to read these two signals on this module.Any suggestions how to do this?
