    We use Mitsubishi FX3u PLC and Beijer T7A HMI. Adding extra HMI (one or more) is not a problem at all. Periodically, we do it on customers demand. You only, have to tick option "OPC UA Server" in the project for the main HMI. In the project for other HMI, You have to add "OPC Client" as controller instead of the main PLC. All HMI to be connected with network cable through Ethernet. Note, that PLC is not affected. It means any PLC can be used. Beijer guys told, that these HMI are much better than their older E1000. A couple years ago our managers decided to migrate to Mitsubishi GOT panels, but recently decided to return back to Beijer. They offer a lot of advanced options to use and really good.

    I am interested in C# examples for Mitsubishi PLC as well. Read in one forum that this language is not popular among PLC programmers. Several years ago I looked for a project to communicate between PC and Schneider PLC. The only example I found was written for Visual Basic.

    Bought by chance in the internet the Mitsubishi PLC FX3uc-64MT/DSS. When delivered, discovered, that there was no power connector included. Can somebody recommend, please, where and what should I look for, to test the unit? Is it commercially available?

    Thank You Jeremy, this is very interesting. If I find Red Lion HMI, will try the scripting. Another questions: what operating system are used by HMI? Beijer IX use Windows CE, the Siemens panels as well (?). Mitsubishi GOT have their own operating system. What about others? A couple or years ago some HMI with Android were offered in the internet.

    Hi to everybody. Last years I use C# for programming Beijer IX panels and enjoy it. Found some solutions which may be usefull for other HMI as well. The questios is, what languages they demand for scripting? In Mitsubishi GOT manual is written "C-like language". What about other platforms used usually with Allen Bradley, Schneider, Omron, Siemens...?

    Just tried the qrencode-win32. Works OK, but this is not what is wanted. I do expect a script linked to some tags, and every time when the script is launched, an appropriate QR code image is renerated and shown on the HMI screen. Unfortunately, I haven't got the suitable software to test the example from Siemens. Did somebody try it?

    Dear MrAutomation, thank You for the answer and good advice. We use Beijer iX Panels as HMI. They based on Windows CE operating system. I will try solution You recommend. Does it work with Windows CE? Before, an example for generating a QR code for Siemens WinCC was found: http://support.automation.siemens.com/AR/llisapi.dll?func=cslib.csinfo&objId=51418740&mlfbclusterid=34502257&nodeid0=16502367&load=content&prodLstObjId=21848767&subtype=130000?=en&siteid=cseus&aktprim=0&objaction=csview&extranet=standard&viewreg=AR As far as I know, WinCC use for HMI the Windows CE as well.

    Thank You Crossbow, I loaded program and parameters into memory cassette, then made transfer from the the cassette into PLC. After that switched off PLC and removed cassette. After second start, the parameters mismatch was noticed. Is it possible after pressing button on the memory cassette for transferring program and parameters, that parameters are not being transferred into PLC? What is safer, ask service Engineer simply put the cassette into PLC and run, or ask him (her) to transfer program from cassette, then remove it and run without the cassette?

    Dear Crossbow and Theo V, thank You very much for the answers. After first try to transfer program from memory cassette into PLC noticed, that PLC parameters migrated to default state. So, registers D0..D255 were not latched (as they were set in my project) and that caused problem. What was wrong?

    Hi Fred, thank You for the answer. Yes, we are slave and waiting for somebody's orders. As I understood You, there is no build in tools in FX3U, testing if a message received by slave and the only solution is to compare the current and previous values of a signal which is supposed to change itself periodically?

    We use this adapter with FX3U PLC for Mosbus communication. It works, but, if Modbus cable is disconnected it keeps the latest information received. The task is to reset info in such situation and put an error message on HMI screen. I watched the corrresponding error registers and found, that their values do not change whethear the cable is connected or not. Any ideas, what is wrong?

    Hi, we consider a new approach in fixing problems: Instead of sending a maintenance Engineer with a laptop and new PLC program, post the program on a memory cassette(e.g. FX3U-FLROM) with a short manual how to install it. Did somebody try this? Is it safe? What is better, leave the external memory on PLC and run or transfer the program into PLC and then remove it?

    Learnt recently from my colleagues about diference in use the command "To" in simple ladder and in structural project. The case relates to FX3u PLC setting anologues cards. If it true or not for Q and other series, is not clear. in ladder: n1, n2, S, n3 for example K0, K0, H5555, K1 in structural: S, n1, n2, n3 for example H5555, K0, K0, K1
