Is it possible, and how, to add a value to a variable after a certain time perioid passes?

For example I would like to add a value to variable, after each second.

This is for counting kj/s and after a 24h perioid passes convert kj/s to kwh and add this to another variable. This is for energy measurement

Well, thanks to Tomas, got it working :) Thanks and sorry about the previous ranting :)

Nothing went well.

I have the proxy ID set, and I can debug the controller, so it means that I am connected but when I try to upload the changed parameters in proxy parameters it says:

Controller is only partial attached, please attach against real controller.

Host: IP-address of the controller
Port: The port where the controller resides.
Serial number: all zeros
Device: Neuron S103.whatever

Result: No go.

So to speak, this is really starting to piss me off

Deploy parameters are correct, ip address, port, serial and controller type. Still complains about partial connection..but anyhow, if I want to use the proxy, which is it?

Manual says on page 44: http://proxy.unipi.technology:6677

And the default in mervis is: http://proxy.mervis.info:6677/

Which is it? And if it is the http://proxy.unipi.technology:6677 it should be corrected in the mervis also to be default.

Thanks.

Well..the problem is that the proxy is disabled. The controller is 200km away, running just fine. Now I just would need to change some things in the program, without having to drive to the site.

And the instructions about the whole proxy thing give me cold sweat.

Whats this: Proxy ID - a unique ID string (Proxy ID)
And where do I get it?

Can I upload the configuration remotely if it says I am partially connected:
Upload the configuration to UniPi and perform a device reboot

What If I want to use TCP without proxy to upload new program?

I am trying to remotely program the Neuron S103 with mervis and even though I have set the connection parameters in mervis (port) it says to me that the controller is only partially attached.

Are there any other ports that need to be open other than 12346 (or whatever it is by default)
(and port 80 for HMI)

I have made a port forwarding from outside port 20000 to 12346 inside, and I can debug and connect just fine, but can't deploy solution.

Do I need more ports open?

Ok..This is something new to me. Could you please give me details?

Can this python script run "inside" the Neuron S103, or does it need external raspberry pi for example?

I was in the assumption that the unipi = raspberry with extra modules.

At first it needs to be connected to dhcp. Then UDP works. After you have first made successful contact you can update the ip-address and disable dhcp.

You need to update the controller via: PLC -> PLC operation -> PLC setup -> Upload Configuration

Correct me if I am wrong :)

If we need to log some values as a trend, it will not work, without internet connection, ever?
