Julian Feinauer commented on PLC4X-274:
---------------------------------------
I just looked up in the code and the default is 1 second timeout:
{code:java}
private static final long READ_TIMEOUT =
CONF.getLong("org.apache.plc4x.java.opm.entity_manager.read_timeout", 1_000);
{code}
See in PlcEntityInterceptor.java
> org.apache.plc4x.java.opm.OPMException: Timeout during fetching values
