3.4.5 Structure of the Internet data block (IDB)
The IDB is created by the Internet wizard in STEP 7 Micro/WIN 32. The structure of the IDB
is shown in the following table.
The IDB immediately follows the NDB in variable memory. Since the length of the NDB
depends on the current configuration, no general start address can be given for the IDB. The
byte offsets in the table below all relate to this start address.
