Hi, what are the reasons if I "lose" my connection and how can I solve the problem (without restarting the CORE)? In my set up I have 3 ctrlX COREs connected to a switch via port XF51. Each CORE has a data layer remote connection to the other two. CORE 1 now lost the connection to CORE 2, but CORE 2 still has a connection to CORE1. After restarting CORE 1 it worked again. Thanks for your help.

Hi, I had problems implementing the Example_BulkReadNodeValues from the CXA_DATALAYER library. I found a solution in which I combined the Example_BulkReadNodeValues and Example_ReadNodeValue and would like to share with you. Please, comment if you have any suggestions for improvement! Declaration: PROGRAM PLC_PRG VAR //read ctrlX Data Layer values //combination of Example_BulkReadNodeValues and Example_ReadNodeValue m_fbBulkReadNode : DL_BulkReadNodeValues; bulkRequests : ARRAY[0..2] OF DL_BulkRequest; // Names of the requested nodes in data layer bulkResponses : ARRAY[0..2] OF DL_BulkResponse; // Values of the requested nodes in data layer nodeCount : INT := 3; // number of nodes that will be requested //project variables for traffic lights 2 DL_bLightRed2 : BOOL; DL_bLightYellow2 : BOOL; DL_bLightGreen2 : BOOL; END_VAR Code: //read ctrlX Data Layer values //combination of Example_BulkReadNodeValues and Example_ReadNodeValue //Data Layer addresses for traffic lights 2 bulkRequests[0].NodeName := ADR('devices/remotes/TrafficLight2/plc/app/Application/sym/PLC_PRG/bLightRed2'); bulkRequests[1].NodeName := ADR('devices/remotes/TrafficLight2/plc/app/Application/sym/PLC_PRG/bLightYellow2'); bulkRequests[2].NodeName := ADR('devices/remotes/TrafficLight2/plc/app/Application/sym/PLC_PRG/bLightGreen2'); //read data from Data Layer m_fbBulkReadNode(Execute:= TRUE, BulkRequests:= ADR(bulkRequests), BulkResponses:= ADR(bulkResponses), Count := nodeCount); // set Execute to TRUE // save data from Data Layer to project variables IF (m_fbBulkReadNode.Done = TRUE) THEN bulkResponses[0].NodeValue.GetValueBool8(Value=>DL_bLightRed2); bulkResponses[1].NodeValue.GetValueBool8(Value=>DL_bLightYellow2); bulkResponses[2].NodeValue.GetValueBool8(Value=>DL_bLightGreen2); END_IF // end access to Data Layer IF (m_fbBulkReadNode.Done = TRUE) OR (m_fbBulkReadNode.Error = TRUE) THEN m_fbBulkReadNode(Execute:= FALSE, BulkRequests:= ADR(bulkRequests), BulkResponses:= ADR(bulkResponses), Count := nodeCount); // set Execute to FALSE END_IF

My training participant can't boot his CORE Virtual. Following message appears while booting "WHPX: No accelerator fount, hr=00000000 failed to initialize whpx: No space left on device Check hardare acceleration in extended properties." We already acticated Windows Hypervisor-Platform-Feature. (Hyper-V is also activated).And following information on hardware acceleration is displayed - so both hardware accelerations are available on the laptop. We selected Windows Hypervisor Platform in the settings and also activated it (see pictures below). Do you have any ideas, whywe cannot boot the CORE Virtual? Thank you.
