Modular EDS provides a virtual slot system ("rack") in which
the components of the CP system sit in virtual "slots" and can
be configured individually. As a result, there are no gaps in
the I/O mapping - only I/Os which actually exist are taken into
account.
The components of a CP system always have this sequence
within the rack:
1. CDVI-DN manifold block
2. CDVI-DN expansion blocks
3. CP output module or valve terminal
4. CP input module
Example of a rack:
