Variants of the system expansion card

Use of the system expansion card
The system expansion card (SEC) is inserted in a slot at the back of the CPU.
The SEC is used to scale the CPU 410 to correspond the maximum loadable process
objects. More detailed information about the scaling concept can be found in the section
Scaling and licensing (scaling concept) (Page 32).
Operation of the CPU is not possible without an SEC. If no valid SEC is detected, the
corresponding CPU does not start up.
If an error occurs in redundant mode during access to the SEC of a CPU, this triggers a loss
of synchronization and a startup block prevents another automatic link-up. You cannot
operate two CPUs 410 redundantly with two different SECs.
