Fig. 1/4: Internal I/O address range

Due to the large I/O address range, considerably more
NC records can be accessed in record select mode via
the field bus, than via the I/O module.

With the field bus module, 10 bits are available for
selecting the NC record number in record select mode.
The maximum permitted number of NC records (up to
1000) of the determined starting programs can there-
fore be accessed.
