-----------------------------------
Summary: S7 is terminating the connection during handshake
Key: PLC4X-134
URL: https://issues.apache.org/jira/browse/PLC4X-134
Project: Apache PLC4X
Issue Type: Bug
Components: Driver-S7
Affects Versions: 0.5.0
Reporter: Mirko Pohland
When trying to connect to my S7-300 I get the following error (stack trace
attached):
{color:#FF0000} org.apache.plc4x.java.api.exceptions.PlcIoException: Connection
terminated by remote{color}
After some debugging I found out that I can fix this issue by doing a small
change in S7PlcConnection.java
From
short calledTsapId = S7TsapIdEncoder.encodeS7TsapId(DeviceGroup.OS, 0,
0);
short callingTsapId =
S7TsapIdEncoder.encodeS7TsapId(DeviceGroup.PG_OR_PC, rack, slot);
where calledTsapId does not contain rack and slot to
short calledTsapId = S7TsapIdEncoder.encodeS7TsapId(DeviceGroup.OS,
rack, slot);
short callingTsapId =
S7TsapIdEncoder.encodeS7TsapId(DeviceGroup.PG_OR_PC, 0, 0);
Now I can connect to the S7.
