Exporting Program Blocks (DB)

When the database contains Struct data type, please note the following restrictions. Please at least add one data member that doesn’t belong to Struct data type into DB, otherwise, the data cannot be imported to EBPro (EasyBuilder). Multidimensional Arrays and Multilayer Structs are not supported.

  1. After building DB, please do the following actions for Struct address

    (1) Copy the complete Struct data.

    (2) Delete data.

    (3) Add a new row.

    (4) Paste data.
