CO4011A-FL
Single Chip CANopen Controller for Remote I/O
The PDO mapping objects have the same structure
for all PDOs. The following Objects are used.

All objects with PDO mapping capabilities (not only
digital or analog I/O) may be mapped to one of the
PDOs.
DS401: Digital Input Objects
The following objects are describing the functionality
of the digital input lines of the CO4011A
Index 5001/2 : Write to Digital Input
The object 5001 and 5002 are implemented for
debug purposes, because the CANopen object 6000
does not allow write access to an input line. With
objects 5001 and 5002 a debug environment may
simulate setting or resetting of input lines. The
CO4011 first scans the physical input lines and then
processes the scanned values with the debug
parameters.
Index 5001 and 5002 make direct bit manipulation of
single bits possible.
Index 5001 enables bit setting by using a bit wise
logical OR conjunction with index 6000 while index
5002 performs a logical AND conjunction with index
6000 and therefore enables resetting of single bits.
Objects 5001 and 5002 are always working in
continuous execution mode. This means that logical
operations with object 6000 are performed in each
internal input scan cycle
