Inserting modules on empty slots
If you replace a BU cover placed on an empty slot with an I/O module when configuration
control is enabled, the ET 200SP distributed I/O system behaves as follows:
● Interface module: When the BU cover is removed, a removal interrupt is signaled. When
the I/O module is inserted, an insertion alarm (wrong module) is signaled.
● CPU: A removal/insertion interrupt is not signaled when the BU cover is removed or when
the I/O module is inserted.

A station master consisting of an interface module, three I/O modules and the server module
is configured in STEP 7 in the following section.
Four station options are derived from the station master with the configuration control:
● Station option 1 with module that is not present
● Station option 2 with modified order of modules
● Station option 3 with empty slot
● Station option 4: Opening a new potential group
