Number of coupling modules in a subrack
The number of CS coupling modules (CSH11, CS12/13/14, CS22 and
CS7) are restricted by two system limits:
•
subrack size
The largest subrack in the SIMADYN D system has 24 slots. As a
subrack must have at least one CPU, theoretically, 23 slots remain.
•
available address space
In practice, these limits are seldomly reached. For CS modules, the L-
and C bus each have 1 Mbyte address space.
The individual CS modules always occupy a constant address space on
the backplane bus.
•
Example
CS7 always occupies 64 Kbyte on the L bus, independent of how
many modules are configured.

Reorganizing a data interface
A data interface can be re-formatted without having to interrupt the RUN
condition or diminish performance.
