Description

nifReadObject

reads the values of objects such as block parameters or communications

parameters from devices.

•

is the descriptor of a link, then

name

must be in the format

BLOCKTAG.PARAM_NAME

•

is a session descriptor, then all links are searched for the given

BLOCKTAG.PARAM_NAME

. The call fails if multiple identical

BLOCKTAG.PARAM_NAME

tags are located on the bus. Index access is not allowed for session descriptors.

•

is the descriptor of a general function block application VFD, then name must be

in the format

BLOCKTAG.PARAM_NAME

•

is the descriptor of a function block,

name

must be in the format

PARAM_NAME

•

is the descriptor of a function block, and the

NIFB_INDEX

NIFB_INDEX_SUBINDEX

macro is used, the index specified is the relative index of the

parameter within the block. Relative indices start at 1 for the first parameter.

•

In all descriptor cases, you can expand

PARAM_NAME

itself to

STRUCT.ELEMENT

format

to represent a named element of a named structure.

In each case,

name

can represent either a variable or a variable list object. You should

determine the size of the object beforehand, possibly with a call to

nifGetObjectSize

If the object is larger than the buffer size specified in

length

, the NI-FBUS Communications

Manager returns an error, and none of the data in the buffer is valid.

Refer to Table 6-5 for an explanation of how to use macros to specify the parameter.

The data

nifReadObject

returns is in Fieldbus Foundation FMS Application format. You

must accomplish conversion of the data to the internal format of your processor and compiler.

Return Values

E_OK

The call was successful.

E_INVALID_DESCRIPTOR

The descriptor does not correspond to a VFD or function block.
This descriptor is no longer valid.

E_NOT_FOUND

The referred object does not exist.

E_OBJECT_ACCESS_DENIED

The NI-FBUS Communications Manager interface does not have
the required privileges. The access group you belong to is not
allowed to acknowledge the event, or the password you used is
wrong.

E_MULTIPLE

The NI-FBUS Communications Manager found more than
one identical tag. The function failed.

E_BUF_TOO_SMALL

The object is larger than your buffer.
