Hi, thanks for the job.
I found functions in UserJS that do the job:

Hi,
I Think you can make a programm that reads value from i2c and send them to modbus.
I create one that read value from zmq and send to modbus.
You have to find and install modbus library.
Then you have to create modbus channel in IDE, connect to the right port, and parse values.
So, to you to read value from i2c.
My code here:
#include <stdio.h>
#include <unistd.h>
#include <string.h>
#include <stdlib.h>
#include <errno.h>
#include <modbus.h>
#include <zmq.h>
#include "zhelpers.h"
int arrondi(float nombre) {
return nombre + 0.5;
}
int main()

int socket;
modbus_t *ctx;

modbus_tcp_accept(ctx, &socket);

Tell me if you need more help.
Giamba
Got it!
Each fdb programme must have an entry in PLC Tasks.
Hi CKB.
Yes it's ok for me now. Tested with example and with my project.
Hi, this is the SSCP Server log. Can U tell me how is managed the login on the RT (maybe cookie with wrong acl) and if the sscp connection have to be permanant keep-alive because it seems to reconnect on each request.

Hi!
It's purely Javascript and DOM.
If you have knowledge in this, you can take a look at http://www.voicerss.org/ which translates the text that you pass to in audio. With Javascript, you fetch all the elements of the DOM until you find those where you set an attribute (data-my-text-to-read) to define it's hhover event. Methode for all recents browsers.
You can edit the sources of the HMI web pages in the web directory of your project directory.
Hope that's help.
As seen in https://kb.mervis.info/lib/exe/fetch.php/cs:mervis-ide:sharkprotocolspecification_user_2017_05_30.pdf,
In port monitor:
On receiving:
So I have a resonse, credentials seems too be wrong, but I have admin - rw on PLC configuration and SSCP Device.
Do you have an explanation ?
Hi,
I test lots of configurations and doesn't work yet.
This is what I have in mervis:
!
And netstat command:
So, plz, can U tell me what's wrong ?
hi @CKB, @tomas_hora ,
Same problem for me, did you find the solution ?
Thanks.
Hi @tomas_hora,
So this is the chart I get of few hours with some unusual peaks and a unfortunate no signal blackout at the end for a couple of minutes.
Could you please provide me a chart that shows on a long term basis multiple 1wire sensors curves to make sure that the product (sensors and hub) you sold on you website are reliable.
Thanks in advance.
Hi,
Ok, now my one wire network is working for a few minutes.
I have put 4+5 together, 3+8 and 6+7, but I have inserted a 150ohm resistor to the data pin of each branch, one branch for one sensor in the middle (1.5m) and one for the star "branch" to the end at 3m.
According to the specification, 150ohm resistor is not suposed to work for the DS2482-X but it's actualy the only way I found to make it works (for a few minutes) whereas without resistor no sensor is found.
Is there a way to modify the DS2482-x configuration register to test diferent PullUp options ?
So the 1 wire is very important for me, it controls solar heating panels and boiler, without this working it's realy a problem.
Thanks to help me to get it working.
