hi victor,
yes I use PI studio, as you see in the image the display is slave therefore I use the modbus master on arduino...
have you got to use the modbus with arduino and flowcode?
thanks

hi Victor
here the photo

hi,
I have seen the videos, but what I would like to do is use the wecon hmi with arduino but using or v8 or v10 flowcode

hi Victor
here the flowcode file

hi Victor
there are problems instead, because I can't read or write registers between arduino and wecon display

Hi Victor,

when I use it with other plc, the display is set as slave and the plc as master, so I think it must be like this also using arduino, the example I'm using I attached before; I would like to use only one master and one slave

Thanks

hi, on the wecon site there is only the manual for the software to create the hmi pages but there is no manual describing the communication protocol, probably because it is possible to set multiple protocols according to need. anyway the hmi display is set as modbus rtu slave, so arduino will have t...

I tried to use the Easy MODBUS Viewer program to check the output from the arduino serial (ttl/serial converter) but nothing is seen, is there a definitely working example with which to carry out tests?

hi, yes I'm trying in all ways and in all configurations, but I can't get the arduino to communicate with the display. this is the link of the manufacturer https://www.we-con.com.cn/en/product_page/190.html. with its software the pages are created and the communication parameters can be set, I set t...

HI,
these are the examples
Thank you

hi Victor_au, I don't have a specific project, I'm trying to use the examples but I don't see arduino communicating with the wecon display, I'm simply trying to write a value from arduino to a display register via modbus RTU; the display is set with the modbus RTU slave all function communication pr...

Hi everyone I would like to use a Wecon hmi display to view the value of some variables and change the value of others by reading and writing registers, the display in question communicates via the modbus protocol, but I can't connect the arduino mega to the display, I can't is there a way to establ...

good morning,
probably not the right place, but on the site I could not find an email address to write to.
I tried to make a purchase on your site but at the time of payment paypal says that your payment page does not work. how should i do?
thank you

hi,
sure, i just wanted to know if anyone has ever used a wecon display with arduino using flowcode, it is not clear to me how to write on the hmi
and read from it, i have not found examples.
Do i have to put both modbus master and slave in flowcode?
thanks for the help

hi Abhi,

I don't have the hmi datasheet, but in the software it's possible to set the protocol type (master slave ect)

thanks!

hi all,
this is the first time i use flowcode 8 and i am trying to interface an HMI to arduino mega using modbus protocol, but
i don't understand how to do it, can someone help me?
thanks for your help

here the link for the hmi

best regards

i have solved thanks!

hi Steve,
i have tried but when try to download the project to miac i have this error
"pic compiler toolchain is not installed"

hi at all,
i have a flowcode v8 licence but i also have a miac 8 bit whit his licence, how can i use the last one in flowcode v8?
thanks

ok thank!!!
and so after that i can also check the value of the variables, is it right?
thank you
regards

Hello everybody
to use the incircuit debug and the ghost function, is it enough to buy the "test & debug pack" or i need also the E-BLOCKS2 ARDUINO SHIELD?
thank you in advance
regards!

solved!

i reinstall all and now works

Hi everyone!
i installed now flowcode V8 but if i try to compile to chip i have an error "avr compiler toolchain is not installed" , i have download it and install it but
nothing change

i can i do?

thanks
