--------------------------------------------
Summary: [camel-plc4x] Plc4XEndpoint doStart called multiple times
Key: CAMEL-24171
URL: https://issues.apache.org/jira/browse/CAMEL-24171
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 4.21.0
Reporter: Francesco Spampinato
Hi,
I'm using camel-plc4x to acquire data from plc machines with a camel
integration.
In particular i'm using modbus and s7 protocols to acquire data.
{code:java}
from(timer("modbus").period(5000))
.pollEnrich(plc4x("modbus-tcp://localhost:502")
.autoReconnect(true)
.tags(Map.of("coil-1", "RAW(coil:1)")), 5000)
.routeId("modbus")
.log(LoggingLevel.INFO, LOG, ">> Message from modbus ${body}"); {code}
{code:java}
from(timer("s7").period(5000))
.pollEnrich(plc4x("s7://localhost:102")
.autoReconnect(true)
.tags(Map.of("var1", "RAW(%DB1.DBX0.0:BOOL)")), 5000)
.routeId("s7")
.log(LoggingLevel.INFO, LOG, ">> Message from s7${body}"); {code}
In the modbus route Plc4XEndpoint is started only once when the routes start's
up.
This method is only called once
{code:java}
@Override
protected void doStart() throws Exception {
super.doStart();
ClassLoader cl = getCamelContext().getApplicationContextClassLoader();
this.plcDriverManager = new DefaultPlcDriverManager(cl);
} {code}
In the s7 routes instead, doStart is called on every poll cycle, causing
DefaultPlcDriverManager to be reinstantiated and forced to reload all available
plc protocols.
