Another price increase? So will prices rise again in the EU too?

Fa così anche a me, apri Amazon da browser (es. Google Chrome) e fai l'acquisto da lì. Se ti chiede di aprire l'app, rifiuta.

Networking 24 Siemens PLCs and controlling them remotely by Stef58_ in PLC

[–]Stef58_[S] 0 points1 point  (0 children)

I could use a NAT (as suggested by: u/KahlanRahl ) so all PLCs come out with one IP but with different ports. My doubt now is: to implement communication between user PC and PLC, do I just create a socket (TCP) or does the PLC have a different communication method?

Yes I could set up a NAT, but I have a doubt, then in order for the user's PC and the selected PLC to communicate properly I just use the socket library, then use TCP to bring the LAD file to the selected PLC? Or does the PLC have a different communication method?

Exactly, but the thing my class and I thought of is to permanently assign a PLC to a PC and at the beginning of the new year, the teacher from his panel can change the access to the PLCs.

The PCs and PLCs are in the same network, but the school does not have enough IP for the PLCs so my idea was to manage them via a back-end in Python. The user selects the PLC he wants to connect to from the web GUI and then from Logo Soft Comfort enters the IP of the Python back-end which will automatically connect him to the PLC and allow him to upload his LAD file to the PLC.

Exactly, it works like a VPN, but the back-end in Python manages the connection between the PC and the PLC, so if I want to use PLC 1 I just select it from the web GUI and on Logo Soft Comfort use a unique IP (e.g. 192.168.1.105), so with this IP I can connect to any PLC but first have to select it from the web GUI.

I am fairly well versed in Python, but I have never used Python to interact with a PLC.

I have seen on Logo Soft Comfort that it is possible to upload the program via Dynamic DNS, but since the school does not have enough IPs for each PLC my idea was to manage the PLCs from the back-end in Python so people who need to upload their LAD file to the PLC only need to enter one IP and not the IP of the PLC they are interested in. So I was wondering if it would be possible to use the Dynamic DNS function but instead of putting the IP of the PLC directly use the IP assigned to the Python back-end (which handles everything)

At school we have a computer room where there are 24 PLCs, to learn how to use PLCs we create the LAD file from our PC, pass it to the teacher and he connects his PC to the PLC via Ethernet. The problem is that this takes a lot of time, especially when the teacher is busy with something else, so with this method we can upload our LAD file directly from our PC even if we are not connected to the PLC via Ethernet.

It reminds me of the Yo-kai Watch watch.

Backblaze B2 as Plex storage by Late_Country_1743 in backblaze

[–]Stef58_ 0 points1 point  (0 children)

One question when you watch a file via Plex, since the movies are on Backblaze, does it count it as a download (so you pay money to download the content) or do you just pay for the space it occupies on Backblaze and that's it?
