Obtain data using the Emulation module with Modbus?

[ FlexSim 18.2.2 ]

Hello How could I obtain data using the Emulation module with Modbus tcp / ipv4 either in JAVA or in c ++? If possible with an example to understand its operation.

What data are you trying to obtain? Most of the data would would want is found in the "Variables" Tab of the Emulation properties window where you can read and write to the PLCs, Servers,or Client.

Maybe, the time it takes to assemble a product.

But what I need is a way to get some kind of data in a program in JAVA or c ++, I was trying to connect JAVA with FlexSim using sockets, but I have not obtained results.

A basic script to communicate with a C++ or Java server using FlexSim as the client is as such

socketinit();
int client=0;
client = clientcreate();
string hostname="127.0.0.1";
int port=502;
clientconnect(client,hostname,port);
print(client);
clientsend (client, "TestConnection");
print(clientreceive(client, NULL, 1024, 0));
clientclose(client);

The Emulation module in FlexSim is very specific to Modbus and OPC connections

thanks, this script, in what part of the program do I place it?

I could re-publish the answer, apparently it is no longer available.

If you could that would be great so it can still be a good resource for others.
