Beckhoff with ADS protocol (0.0.8-SNAPSHOT)
Hello everyone,
Im' able to connect to my beckhoff PLC, read a value, but sometimes the read just "hang". The code below works like half the time.
Some time, I run the program, it reads the value, sometimes it just hang on the "execute".
I dont know what Im doing wrong.
PlcDriverManager driver = new PlcDriverManager();
try {
//
PlcConnection connection = driver.getConnection(
"ads:tcp://10.10.11.77?sourceAmsNetId=172.29.48.1.1.1&sourceAmsPort=36&targetAmsNetId=5.62.206.200.1.1&targetAmsPort=851");
if (connection.isConnected()) {
if (connection.getMetadata().canRead()) {
PlcReadRequest.Builder builder = connection.readRequestBuilder();
builder.addItem("value-1", "MAIN.Rand_1:DINT");
PlcReadRequest request = builder.build();
request.execute().whenComplete((response, exception) -> {
Integer x = response.getInteger("value-1");
System.out.println("READ DONE: " + x.toString());
});
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
Dong the same in C# with the TwinCAT dll from beckhoff works flawlessly:
int handle = tcClient.CreateVariableHandle("MAIN.Rand_1");
for (int i = 0; i < 1000000; i++) {
tcClient.Read(handle, dataStream);
var v = binRead.ReadInt32().ToString();
Console.WriteLine(v);
dataStream.Position = 0;
}

Hi,
In the past I had seen this happen (Especially as I got my new laptop)
For ADS you have to setup an ADS-Route … When trying to connect to my Beckhoff PLC for the first time, it also was hanging as I didn’t have a route configured.
Could you please confirm you have your routes setup so you can reach
5.62.206.200.1.1 from 172.29.48.1.1.1?
And a WireShark dump would help a lot.
Chris

Ty Stephen !
It makes total sense. And you're right the beckhoff plc offers a couple of ports...
Ty you very much, really appreciated !
I was wondering, is there a "time frame" or plan to do "Notification" on the ADS driver ?
That would be awesome :)

Patrick,
Since you are trying to communicate with the PLC from two different PC
apps on the same network, you will invariably have errors such as you
experienced. This is largely due to the deterministic requirements of
the PLC and the limited timeframe allotted for such communication. Also
worth noting is the precendence of which comes first, and this comes
forward even more when you have a programming (ie PLC programming
software) terminal connected since the proprietary PLC programming
software often takes ownership of the connection and will bump other
connections as it suits. It was one of the reasons most brands have
multiple communication ports available to use.
Regards,
Stephen

RE: Beckhoff with ADS protocol (0.0.8-SNAPSHOT)
Posted by Patrick Boisclair <pb...@noovelia.com>.
Sorry I was actually not clear.
Im running the PLC4X program from IntelliJ .
When I upload the TwinCAT program into the beckhoff PLC and it runs from itself, it works.
When I have Visual Studio with the TwinCAT program running from my PC (Connected through TwinCAT developer mode), the PLC4X programs hangs (still running it from IntelliJ).
It just its cool to see the TwinCAT variables "live" fron VisualStudio while developping the PLC4X program that connects to it.
Does it make sense ?

Hi Patrick,
so was the problem actually a VisualStudio problem or something we can improve?
If you say: „PLC program only in the PLC itself“ … you’re not running the PLC4X program on a PLC? So you mean if you run the program from the commandline, it works and in VS it hangs?

Ok I found out what the problem is.
For a reason when the PLC program is running from Visual Studio (TwinCAT), for a reason with PLC4X it sometimes hangs.
If I shut down Visual Studio and run the PLC program only in the PLC itself.. works fine.

Hi Patrick,
welcome to our list.
There is one big difference (if you are calling the code you posted in a loop):
Internally the driver automatically does the translation from a symbolic address to a handle and to use that handle to read and to give back the handle when closing the connection.
Perhaps if you run your loop just around this part:
request.execute().whenComplete((response, exception) -> {
Integer x = response.getInteger("value-1");
System.out.println("READ DONE: " + x.toString());
});
Then it would be a similar scenario.
If this isn’t solving the problem, could you possibly do a WireShark recording oft hat communication and attach that to a Jira issue on: https://issues.apache.org/jira/projects/PLC4X/
This would be the best way to help us find and possibly resolve the issue.
Hope that helps,
Chris

Its not even in a loop in the JAVA code.
Just start the program., hangs half the time.
Trying to figure out what im doing wrong.
I tried the loop like this:
for (int u = 0; u < 10; u++) {
request.execute().whenComplete((response, exception) -> {
Integer x = response.getInteger("value-1");
System.out.println("READ DONE: " + x.toString());
});
}
It never goes to 10 reads before hanging. (sometimes 0 read, sometimes 2, sometimes 7...)

builder.addItem("value-1", "MAIN.Rand_1:DINT");
PlcReadRequest request = builder.build();
request.execute().whenComplete((response, exception) -> {
Integer x = response.getInteger("value-1");
System.out.println("READ DONE: " + x.toString());
});
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
Dong the same in C# with the TwinCAT dll from beckhoff works flawlessly:
int handle = tcClient.CreateVariableHandle("MAIN.Rand_1");
for (int i = 0; i < 1000000; i++) {
tcClient.Read(handle, dataStream);
var v = binRead.ReadInt32().ToString();
Console.WriteLine(v);
dataStream.Position = 0;
}

AW: Beckhoff with ADS protocol (0.0.8-SNAPSHOT)
Posted by Christofer Dutz <ch...@c-ware.de>.
Hi Patrick,
welcome to our list.
There is one big difference (if you are calling the code you posted in a loop):
Internally the driver automatically does the translation from a symbolic address to a handle and to use that handle to read and to give back the handle when closing the connection.
Perhaps if you run your loop just around this part:
request.execute().whenComplete((response, exception) -> {
Integer x = response.getInteger("value-1");
System.out.println("READ DONE: " + x.toString());
});
Then it would be a similar scenario.
If this isn’t solving the problem, could you possibly do a WireShark recording oft hat communication and attach that to a Jira issue on: https://issues.apache.org/jira/projects/PLC4X/
This would be the best way to help us find and possibly resolve the issue.
Hope that helps,
Chris

Betreff: Beckhoff with ADS protocol (0.0.8-SNAPSHOT)
Hello everyone,
Im' able to connect to my beckhoff PLC, read a value, but sometimes the read just "hang". The code below works like half the time.
Some time, I run the program, it reads the value, sometimes it just hang on the "execute".
I dont know what Im doing wrong.
PlcDriverManager driver = new PlcDriverManager();
try {
//
PlcConnection connection = driver.getConnection(
"ads:tcp://10.10.11.77?sourceAmsNetId=172.29.48.1.1.1&sourceAmsPort=36&targetAmsNetId=5.62.206.200.1.1&targetAmsPort=851");
if (connection.isConnected()) {
if (connection.getMetadata().canRead()) {
PlcReadRequest.Builder builder = connection.readRequestBuilder();
builder.addItem("value-1", "MAIN.Rand_1:DINT");
PlcReadRequest request = builder.build();
request.execute().whenComplete((response, exception) -> {
Integer x = response.getInteger("value-1");
System.out.println("READ DONE: " + x.toString());
});
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
