About c-u

Hi Nick, thank you very much. We tried your code in the sample and there its working.  We will update you when we integrated the solution into our realtime bundle and tested it properly.   Best regards, Chris   ... View more

Hi Nick, we successfully updated our ctrlX to 1.14: The read via the web ui still works as expected:   But with the same code snippet as above (built with the SDK v1.14) the read still returns a DL_TYPE_MISMATCH. Can you double check that the versions of our installed apps are compatible?  The only difference (we can see) between your and our setup are the different Ethercat devices and maybe a slightly different build environment.  What would be the next steps to find a solution?

Hi Nick yes the read via the web ui works and returns the expected values. We will update to 1.14, run the snippet again and let you know about the results.   Best regards Chris ... View more

Hi Nick,  thanks for your reply, we used your code snippet (with no changes besides the Ethercat-Address, ObjectIndex and SubIndex), but we still get following result: Client connected _data.shareFlatbuffers(builder) DL_OK _client->readSync(...) DL_TYPE_MISMATCH   Since we used exactly the same code, we assume we might have some inconsistencies/problems with our versions. Our used versions are: SDK: SDK-V-0112 EthercatMasterApp: 1.12.0 ctrlX Release: RM21.11 (release from November 2021) What would be the next steps to solve the problem?  Best Regards Chris   ...

Hi Nick, thanks for the reply, we tried to do the read the SDO synchronously with following minimal example, but we still get a DL_TYPE_MISMATCH as result.  #include "comm/datalayer/datalayer.h" #include "comm/datalayer/datalayer_system.h" #include "comm/ethercat/master/fbs/sdo_generated.h" // ... further includes int main(int ac, char *av[]) { comm::datalayer::DlResult result; comm::datalayer::DatalayerSystem datalayer; datalayer.start(false); // connect to client // * in process communication (runs as bundle of rexroth-automation) use factory()->createClient() // * inter process communication (runs on same target) use factory()->createClient(DL_IPC_AUTO) // * on other device use factory()->createClient("tcp://<ip>:2069") comm::datalayer::IClient *client = datalayer.factory()->createClient(DL_IPC_AUTO); if (client->isConnected()) { std::cout << "Client connected" << std::endl; } else { std::cout << "Client not connected" << std::endl; } comm::datalayer::Variant data; do { uint16_t address = 1003; uint16_t objectIndex = 0x6041; uint8_t objectSubIndex = 0; flatbuffers::FlatBufferBuilder flatBufferBuilder; auto sdoRequest = comm::ethercat::master::fbs::CreateSDORequest(flatBufferBuilder, comm::ethercat::master::fbs::Addresstype::Addresstype_fixedphysical, address, objectIndex, objectSubIndex, comm::ethercat::master::fbs::SDOFlags::SDOFlags_noFlags); auto sdo = comm::ethercat::master::fbs::CreateSDO(flatBufferBuilder, sdoRequest); flatBufferBuilder.ForceDefaults(true); flatBufferBuilder.Finish(sdo); std::cout << "------------------StartCycle--------------------------" << std::endl; result = data.shareFlatbuffers(flatBufferBuilder); std::cout << "data.shareFlatbuffers(builder) " << result.toString() << std::endl; result = client->readSync("fieldbuses/ethercat/master/instances/ethercatmaster/device_access/coe/sdo", &data); std::cout << "client->readSync(...) " << result.toString() << std::endl; std::cout << "------------------StopCycle---------------------------" << std::endl; std::this_thread::sleep_for(std::chrono::seconds(1)); } while (!endProcess); }   We would appreciate any information that could help us to resolve this issue.
