Configuration and Parameterization of the Modules

Bus System
3.8 Configuration and Parameterization of the Modules
3.8.1 Process Data Channel of the Bus Controller
The process data channel , which has been parameterized as PFC interface and
which requires 2-byte I/O data, is used for communication between WAGO-
I/O-PRO and the run-time system of the field bus controller as described
before. The register interface that has been implicitly allocated for the
identification "750-833 4-byte process data channel “ and that must be
explicitly activated for "750-833 2-byte process data channel “is not usable by
the user and should not be used. If none of these interfaces are used, the
process data channel can be projected with a length of zero.
(750-833 No process data channel).
