Specialfeatures of the modules 1×counter/16×digital input and SSI interface:
z Themodule1×counter/16×digital input always assigns the next to last and
theSSIinterfacemodulealwaysthelastofthePDOsused.
z The modules cannot be assigned to PDO1 and PDO2. Thus, only eight of
these modules can be used in a system.
z The modules assign a whole PDO (8 bytes) each.
The transmission times of the input / output signals within the I/O system IP20 can
be calculated with a formula.
