hutcheb opened a new pull request #174: URL: https://github.com/apache/plc4x/pull/174 Add extended register/file record read only support, function code 20. This allows you to query data within the 60 memory range. The 60 memory range starts at file 1 address 0 (60). Each file has a length of 1 so 61 would be the first address in file 2.

Summary: Connection die in multithreading
Key: PLC4X-220
URL: https://issues.apache.org/jira/browse/PLC4X-220
Project: Apache PLC4X
Issue Type: Bug
Components: Driver-S7
Affects Versions: 0.7.0
Reporter: Stefano Bossi
Attachments: capture01.pcapng, capture02.pcapng
Dear developers,
I wrote a test application to show you the problem as requested.
The test app fire a couple of thread which read a field in a DB (Siemens 1200
S7) continuously; the problem is that after some seconds one of the two thread
fire an untrappable exception and the software dies.
Here is my code:
```java
package it.fox;

public class App {
private static final Logger logger = LogManager.getLogger(App.class);
public static void main(String[] args) {
try {
PlcConnection plcConnection = new
PooledPlcDriverManager().getConnection("s7://192.168.1.192?controller-type=S7_1200");
if (plcConnection.getMetadata().canRead() ) {
Poller01 poller01 = new Poller01();
poller01.start(plcConnection);
Poller02 poller02 = new Poller02();
poller02.start(plcConnection);
} else {
logger.error("This connection doesn't support reading.");
Thread.sleep(5000);
}
} catch (Exception exception) {
logger.error("Error connecting to the PLC", exception);
}
}
}

Re: Build Server changed ... working on it ...
Well the main issue was that our builds were relying on some tagged nodes that weren't moved to the new server yet. I had to re-configure my sonarcloud token as that wasn't moved and without it the build failed. Nothing too complicated, but had to be done.
