Hello everybody, could please someone give an idea I want to communicate to AS332 via UDP. I have tried and it works, but the problem is: to create an UDP socket i have to set-up first, statically (!!??), the comms partner IP address But: i don't know the partner's IP address. There could be different partners. I want the PLC to obtain the partners IP address from the partner's query just to answer. And I don't understand, why the socket is connected to the alien's IP address, it must be connected to the own IP address, because the first task of an UDP socket is to "listen", isn't it?  So my questions are: - how to receive a packet from any partner via UDP, not setting-up the partner's IP first? - can I use dynamic destination IP address for the "SSEND" instruction? - can I have access to the whole L3 or L2 data packet, where I can obtain the client's IP address from? Thanks!

Solved.

I didn't manage to insert a picture right into message body. How to do that? It requires me to "remove formatting" don't understand what it means

Hello Neverov I am. This is not my case. My case is labels area. I use Latch 1 type, which is selectable here Should it be retained while powered off? Snap8.bmp

Dear All, I have iQ-R R08ENCPU and I declare variables as var_global_retain but they are not actually retained The battery is OK, is particular, the PLC clock is OK Need strongly any ideas, where am I incoirrect Thanx.

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.

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)?

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

Yes. Sorry, this doesn't let me attach files. Could you please check here https://drive.google.com/drive/folders/17nRtUVEQspjrn5j7Qr4CHrTlleauuHbq?usp=sharing

Yes

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... ((

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.

Dear all, Can anybody please help with the following, I'm not familiar with the CS1G-CPU44H. My customer can't restore program from SD card. because some files are absent. Can anyone say, if there really something absent, or it is possible to restore program with these files. - autoexec.obj - autoexec.std - comments.cmt - programs.idx - symbols.sym   Many thanks.  

Dear sirs, I have HMI NB10, installed on a machine that actually works, and I have uploaded a project with NB-Designer (v1.5.2). The project has been uploaded without errors. But after that NB-Designer cannot decompile that, an error appears. What could be the reason of that? Thank you.

Joe E, thank you, I will check that.
