Hi all! In the older SafeLogic SLc I could customize input/output process data and I used only 12 input byte/12 output byte (Sercos): for me was sufficent. Now I have a TwinCat project with only one SAFEX C.15 (EtherCat slave) and in the Process Data obtain already 66 output byte/46 input byte. Is possible customize the process data to reduce exchange input/output bytes? Thanks in advance.

Thank you for the resoponse. I understand your example but I have another question about. For OPC Client I have CXA_OPCUAClient library, for Ethercat CXA_EtherCatMaster library. For my case (system/resources/network/interfaces/XF10/addresses) which library CXA_XXXXXXX I must use? Thank you.

Hi, I try to read some system data layer. If I try to read a type STRING or BOOL, I can read data in PLC with function DL_ReadNode without problem. For exampIe: if declare Value as type Bool and I can read: system/resources/network/interfaces/XF10/ipForwarding if I declare Value as type STRING, I canb read: system/resources/network/interfaces/XF10/mode But If I try to read OBJECT: system/resources/network/interfaces/XF10/addresses DL_ReadNode return me always ACCES_ERROR(4). In this example how I must declare Value to read: system/resources/network/interfaces/XF10/addresses with DL_ReadNode function? Thanks.
