GT2000 online simulation doesn't work

[_Pavel_]

Dear sirs,

could anyone please help with the following

Trying to establish online simulation via USB, HMI GT2712-STBA, CPU Q03UDECPU.

The simulation doesn't work, HMI simulator shows empty data fields. USB connection with CPU is OK, the GX Works sees the CPU via USB.

What could be the reason?

Thank you.

Am i reading this correctly you are using the GT Simulator to connect to the Q03UDE via pc usb GT27 and then the Q03UDE via .....(ethernet) ??

Hello Gambit

Sorry you question is not quite clear

Q03UDE is connected to PC via USB, that's all

Sorry, this doesn't let me attach the picture, I don't understand why... ((

ok so it's just GT simulator via USB to the Q03UDE ?

Yes

Hmm strange that should work. So you've setup the simulation setup to usb ? Tools => simulatr = set

Yes. Sorry, this doesn't let me attach files.

Could you please check here

Tried also different USB cables (though GX Works works with any of them) ...

Did you try a small project without the cc-link just QnUDE ?

Dear Gambit, it seems I've found the reason.

All the variables in my HMI have address like "0-0 D1000", so for the register address I have to use "Network No" and "Station No"

If I just put "D1000" (i.e. "Host") then my normal connection (which is CC-Link RS485) doesn't work.

But when I just put "D1000" (i.e. "Host") then online-simulation via USB starts working

How to do correctly, so that both main CC-Link RS485 connection and online-simulation would work (if only possible)?

[Gambit]

Maybe the CC-Link driver isn't supported by the simulator. But why use that anyway when the GT27 and Q03UDE both have ethernet ?

This is the existing system I'm retrofitting now. A number of remote i/o stations as well as an HMI connected into CC-Link RS485 network. I don't know why the vendor made that way )

Original HMI was GT1000 but it had Ethernet as well.
