Check for success and any other status of interest. For
example, application operation may depend on I/O present,
or expected I/O may be verified.

AcroBASIC Language Access to CANopen I/O
All “objects” (for example steppers, encoders, axes, and masters) in
an ACR controller may be accessed via bits and parameters as well
as commands. In many cases, (for example, ADC inputs) the values
may be accessed only through bits or parameters. An external
digital input or output is the same in function and use as an on
board digital input or output, and are used in the same way in the
language. This is true not just for
SET
and
CLR
, but for
IF
,
WHILE
,
INH
,
LD
, and any other command that has a flag as an argument. This
also applies to using parameters with analog I/O. To be consistent
with the current language, extend all existing on board I/O
functionality to external I/O, and facilitate backward compatibility
with existing applications, external I/O are represented with bits and
parameters in exactly the same way onboard I/O is.
Network and Node Information Parameters and Flags
After ACR9000 has started the CANopen network, and discovered
and characterized nodes on the network, it fills in an information
parameter block for the network and each discovered node. It also
updates the Extended I/O Control/Status flags shown below.
