Hi Toringej

I tried your advice but doesn't work. I don't know where is problem

Hi Claes

I'm still trying to find out problem. I'm reinstall ubuntu and install proview again, I don't know if exist log when occured some error during install package.
When I run runtime editor I have this log. Could you give me some advice when can I find some manual(debug, forum) which help me identify problem.

Hello all, I was reading this topic because I am tired about failure with Arduino USB comunication.

Can some one please resume, step by step, how I can install latested Arduino sketch to use Modbus TCP?

Thanks in advanced

Hello all involved in Proview, Arduino and Modbus TCP

I am really needing some help/guidelines to try to put it working.
I already follow the advices from this topic but I could not put it working.
After careful reading I understood the modpoll is a tools were I can check if ModBus is working in Arduino and it is, when I run modpoll and change Arduino's pin 7 by LOW/HIGH I see the change in modpoll, very good.

I also follow all recomendations regarding how Modbus objects need to be configured, please see bellow my configuration

Modbus_Master
Modbus_TCP_Slave
--->Address 192.168.1.177
--->Port 502
Modbus_module
--->FunctionCode ReadCoils
--->Address 0
ChanDi
--->Number 7
--->Representation Bit8 (may be here is my problem)

I also add one DI and connect it with ChanDi above,

By reading on of the post I check Modbus_TCP_Slave status and for my surprise is informing:
--> Status (%NONAME-W-NOMSG, Message number 00000000) so different from Normal operating state.

Can some body help me on that? I am really need some support

Thanks in advanced
Best Regards

Hi Ceccon,
To define the format Modbus message you need to create under the Modbus_module the following channel objects:

Modbus_Module (FC ReadCoils, address 0)
\ ChanDi1 with 'number' = 0 (representation Bit8)
\ ChanDi8 with 'number' = 7 (representation Bit8)

note: even you don't use the ChanDi1, this channel object (with number attribute set to '0') is use to define the beginning of the modbus message, the length is define by the representation.

other example with more channel objects (with representation Bit8):

Modbus_Module
\ ChanDi1 'number' = 0 ...... beginning of message#1
\ ChanDi2 'number' = 1
\ ChanDi3 'number' = 2
\ ChanDi4 'number' = 3
\ ChanDi5 'number' = 4
\ ChanDi6 'number' = 5
\ ChanDi7 'number' = 6
\ ChanDi8 'number' = 7 ...... end of message#1
\ ChanDi9 'number' = 0 ...... beginning of message#2
\ ChanDi10 'number' = 1
\ ChanDi11 'number' = 2
\ ....etc

In this example, you have to create ChanDi1 and ChanDi9 (even if you don't use them). Other ChanDI objects are create only if there's used.

Hello Ben, thank you a lot for your help

I did exactly how you wrote, but is not working yet.

You can see in the pictures attached that Modbus_TCP_Slave are receiving packets but nothing happen in the ChanDi with number = 0 until ChanDi with number = 7. I also Did a PlcPgm to check DI but nothing happen.

Please observe also modpoll screenshot and my 3 NodeConfig informations where Port are defined 22, can be something related to that?
There is some privilege access that I need to check?
There is another picture that I can attach to try to make your help easer for you?

I also attach my Arduino sketch in case you need it.

Once more thank you, I am really needing help.
