regarding the development of the Omron Fins protocol
Ok .. I've fixed that glitch in the Plc4xNettyHandler ... however now you would
simply not get any error message. I would strongly reccomend you add an
onTimeout and onError to your chain to make debugging issues easier.
` RequestTransactionManager.RequestTransaction transaction = tm.startRequest();
transaction.submit(() -> conversationContext.sendRequest(tpktPacket)
.onTimeout(new TransactionErrorCallback<>(future, transaction))
.onError(new TransactionErrorCallback<>(future, transaction))
.expectResponse(TPKTPacket.class, REQUEST_TIMEOUT)
.unwrap(TPKTPacket::getPayload)
.only(COTPPacketData.class)
.unwrap(COTPPacket::getPayload)
.check(p -> p.getTpduReference() == tpduId)
.handle(p -> {
try {
//future.complete(decodeEventSubscriptionRequest(tagName, p,
subscriptionRequest));
futures.get("DATA_").complete(p);
} catch (Exception e) {
logger.warn("Error sending 'write' message: '{}'",
e.getMessage(), e);
}
// Finish the request-transaction.
transaction.endRequest();
}));`
