I'm trying to use a KINCO HMI to generate analog output value to connect to my LOGO to simulate a 0-10v analog input ( NAI ).

When displaying the NAI value on my TDE it shows the value for a second and then returns to zero.

I don't know if this is due to the KINCO or the LOGO.

Anyone who has experience ?

I'm trying to build a learning setup to control light intensity using 0-10v output of the LOGO

KINCO HMI--> analog value --> NAI on LOGO --> AQ ( 0-10v)

Thanks

I wanted first to do a simple test to check how it works.

In the KINCO HMI is create a scrollbar and a numeric input blok pointning to the NAI1,2 and 3 at the Logo.

In the videoz you will see that the received value is displyed but then zeroed ( also the value at the Kinco is zeroed). Video KINCO and LOGO

When the analog value is displayed in the HMI itself ( writing to LW 210) it works and when slideing the bar left to right and back the value changes interactively.

I have attached a zip file that contains the LSC file, a pdf showing all settings and 2 videos to show what is happening . Video KINCO ONLY

I really appreciate any input. My alternative is doing this via the TDE display but it is very limited.

Anyone here that uses a KINCO HMI to generate analog values using the scrollbar function ?

The output should be read by the LOGO that will use this input to generate 0-10V signal.

If so, can you please share the code so I can learn from it ?

I manage to read analog signals from my LOGO to KINCO HMI but am unable to do it the other way.

What do you think, should a helper do, if you ingore his entries ?

1. It would be a good idea to use the standard port 502 or following 503, 504 and so on

2. An input register is the reprensentation of an actual value at the INPUT of the Modbus device

3. If you want to hold a value, what do you think is the function of a holding register ?

4. The next problems are the NAIx in the Logo program, they are not able to hold values

You need e.g. arithmetic blocks and VM mappings to hold values in registers, see example in attachment, this is your program changed to arithmetic blocks instead of network analog inputs.

Look to extras, ethernet connections and vm mapping to understand the settings. Change port to 502 in your Modbus device.

It also could be, that the Kinco terminal is working in an other way, i have never used it. The example is only a base working with other Modbus devices i know.

Thanks to all,

As you can see I'm not an expert but enjoying the LOGO for home and aquarium automatyion and learning step by step. Also appreciating your efforts in helping me out.

I will apply your advices. In the meanwhile here is what I build sofar ( i'm using 192.168.0.222 as a testing unit before I copy it to the production Logo's ).

In the KINCO at frame 0 use LIGHT TEST to jump to Frame 10

Thanks again.

I will work it out with your inputs !
