12.3 Overview of Parameters
The structure and encoding for the parameters stored in the I/O module are
described below.
These parameters are organized as registers. A data volume of one word can be
stored per register. Several registers are combined into a table, as some
parameters require that a larger data volume be stored, or are closely tied to
other parameters.
The first 64 registers of the I/O module play a special role. These "base registers"
can be addressed directly as 0 … 63 using register communication. All of the
other registers are "extended registers", which must be addressed entirely via the
table and register index by the function blocks.
12.3.1 Table 0: Base Register
See Section "Register Communication" in this manual.
12.3.2 Tables 50 … 55: Filter Configuration
Tables 50 … 55 contain the parameters for filter configuration. These tables are
structured identically to one another and differ only with regard to their default
standard values.

Registers 0 and 1 save the CAN ID (lower limit) for the specific filter, Registers 2
and 3 the CAN ID (upper limit) for the specific filter.
Register 4 saves the activation status of the specific filter.
