Ok, thank you for the reply, it's not realy valid in my case though as we are looking at using the ctrlX as a IoT gateway and read drive info from a CML65 which has drives connected over sercos, but would be a nice feature for the future to be able to rename the data node when adding a drive with SIP

Thank you for the reply, i take it then that we should stick to requests from applications and not use subscriptions here. One other question, is there a way to rename the drive nodes so we get them for example by ip address instead of serial number as with serial number if a drive is exchanged the reading will stop working without updating the request node addresses so it will then be harder to do a generic application for data collection

Hi, I have a question concerning the DriveConnect functionality to read external drives which i did not really find in the manual. How often does the DriveConnect query the parameters of the added drive and how does the querying work, does it read all parameters or only changed ones? Do we have any defined limits on the drive connect for how many drives we are able to load/read? I'm working on a demo for a customer where we read some drive information from Sercos3 drives connected to a L65 and then a core connected on top of the L65 Core uses NodeRed to add drives and then read information from them which basically seems to work but would like to know what technical limitations we have for this

realized just passing 16#0 as clientId solves the issue for the customer so he does not have to reboot

Hi, I also tried to reproduce the issue again and realized that the issue seems to be related to the clientId. So if i for example declare: posReadRead: DL_ReadNode; and then posReadRead( clientId:= 16#10010101, NodeName:='fieldbuses/ethercat/master/instances/ethercatmaster/realtime_data/input/data/IndraDrive_MPB20_21/AT.Position_feedback_value_1', Value:= readPos); IF NOT posReadRead.Active AND NOT posReadRead.Execute THEN posReadRead.Execute := TRUE; END_IF posReadRead.ErrorID; IF posReadRead.Done OR posReadRead.Error THEN posReadRead.Execute := FALSE; END_IF This gives me an access error when running the code If i then remove the clientId posReadRead( NodeName:='fieldbuses/ethercat/master/instances/ethercatmaster/realtime_data/input/data/IndraDrive_MPB20_21/AT.Position_feedback_value_1', Value:= readPos); But error remained
