The CPI system supports a different number of modules per
CP string, depending on the type of CP master and on the
CPI/CP modules connected.
The CPV Direct is a CPI master.
Modules can be placed in two different groups:
CPI modules (with extended functions)
CP modules (without extended functions)
2)
or one CP output module
Note
Irrespective of the type of CPI/CP modules, not more than
32 inputs and 32 outputs may be connected (sum of all
modules on a CP string).
This means that a CP string can be extended by maximum
