This section describes the Network Variable Outputs, which are
read-only values. No output values are sent over the network, unless they
have changed (except nvoDrvSpeed, which is sent for the heartbeat
functionality, and nvoObjStatus, if update status is requested).

Variable: nvoObjStatus

Format: SNVT_obj_status

Explanation: This Network Variable Output reports node object status
(bit field) and is updated every time its status changes (see

Node Object

Request on page 4-5

).

Valid Range:

Variable: nvoDrvStatus

Format: SNVT_state

Explanation: This Network Variable Output provides the status of the
drive via the Logic Status word (see

Logic Status Word on page C-2

).

Scaling: Bit 0 in the drive is bit 0 (Most Significant Bit) in this variable
when it is viewed using the SNVT_state format (default). SNVT_state
bits, shown in the LonMaker Browser window, are numbered from left to
right.
