AssignNode Node number of the mode to which this node is bound.
AssignObjId Assigned object number of the object in this node to which this node is bound.
AssignSchedId Assigned object number of the schedule object in this node. This should be the same for all four entries and
should be set to SchedulId in the schedule file by the configuration tool.
AssignSubnet Subnet number of the node to which this node is bound.
AssignNrObj There are four entries in this field that specify which nodes are related to the schedule.The four entries specify
which node is bound to the four nvoOccSchudleX ouputs; 0 = nvoOccSchedule0, 1 = nvoOccSchedule1, 2 =
nvoOccSchedule2, 3 = nvoOccSchedule3.
ApplicationType Future use.
BypTime Time between the pressing of the Temporary Occupied button on the thermostat (or initiating Bypass via
DestManOcc) and return to the original scheduled state. DestBypass does not start the Bypass timer. This field
sets the
duration of temporary override
parameter (Installer Setup Parameter No. 26) in the T7300. When the
bypass state has been activated, the bypass timer is set to BypTime. The only valid bypass times allowed are
60 minutes, 180 minutes, 480 minutes, or 720 minutes. If BypTime is not set to one of these times, the
subbase automatically changes the BypTime to the nearest valid time.
DeviceName 18-character field that identifies the node uniquely as one object at the site or project. Contents of DeviceName
is maintained by a management node. If DeviceName is all ASCII blanks, it is unconfigured.
BugVersion Software version per E-Bus Mechanism document.
EVObjectldin EVObjectldin selects the object being referenced by nviRequest. All other EVObjectldin are invalid. The objects
in the node are: 0  Node Object; 1  Thermostat Object.

control of all outputs. (See StatusCmdMode).
UpdateStatus  Report the status (via nvoStatus) of the object addressed by EVObjectdin.
ReportMask  Report the status bits that are supported in nvoStatus by the object addressed by EVObjectldin.
Bits that are supported by the object are set to one. The other fields are set to False.

FileTxTimer Used when the file is opened for SENDING. Explicit address of the RECEIVER (either subnet/node or group

InUseNumber InUseNumber is used by a management node to indicate to all other management nodes that it is
logged on
to
the Excel 10 node and that they should not try to interact with any of the Excel 10 network variables or
configuration parameters. Before the management node reads or writes any network variables, the
management node checks InUseNumber for a zero value meaning no other management nodes are already
logged on
and that a management node can log on to the node. Then the management node writes a number,
1 through 65534, to InUseNumber and periodically writes the same value to indicate that the management
node is still logged on. If there are no writes made to InUseNumber for approximately 60 seconds, then the
Excel 10 resets InUseNumber to zero to automatically log off the management node. Before interacting with
any network variables, the management node verifies that the InUseNumber has not changed. The
management node
logs off
by writing 0 to InUseNumber.
During power up, an application restart, or return to on-line from off-line, the Excel 10 sets InUseNumber to
65535 to indicate to the management node that it is now on-line.
FileStatDomainLen If the last operation was an FR_OPEN_TO_SEND, FR_OPEN_TO_RECEIVE, FR_OPEN_TO_SEND_RA, or
FR_OPEN_TO_RECEIVE_RA, these fields contain the full address of the initiator. If there are multiple
initiators then there may be several operations attempted concurrently on the same set of file transfer network
variables. Each initiator is responsible for checking its own address against the value returned in the file status
to ensure that is was granted requested access. An initiator must not close a file unless it was granted access.
FileStatInfo A sixteen character string with information about the file.
FileStatNode If the last operation was an FR_OPEN_TO_SEND, FR_OPEN_TO_RECEIVE, FR_OPEN_TO_SEND_RA, or
FR_OPEN_TO_RECEIVE_RA, these fields contain the full address of the initiator. If there are multiple

MemFileAddress MemFileAddress specifies the address in the Excel 10 at which the file is located.
MemFileSize For each file there is a record containing the MemFileSize, MemFileType, and MemFileAddress. MemFileSize
is the length of the file.
MemFileType Specifies the LonMark  file type entered into the file directory. Type 1 is a configuration parameter value file.
Type 2 is a configuration parameter template file.
MemFileVersion MemFileVersion (a one byte quantity) specifies the major/minor version of the file. The most significant nibble
contains the major version number and the least significant nibble contains the minor version number.
MemNumFiles MemNumFiles is the number of files in the directory. There is a MemFileSize, MemFileType and
MemFileAddress record for each file following the MemNumFiles.
NrHeatStages 0-3 stages.
MinorVersion Software version per E-Bus Mechanism document.
NodeType NodeType is a four byte ASCII string indicating the type of node (model).
NodeTypeNumber Numeric identifier assigned to the type of node specified in NodeType.
NrFiles Internal use only.
ManualControl When the control loop(s) are disabled and the outputs are controlled manually, then this bit is set to one;
otherwise this bit is set to zero. Manual control of this product is initiated by executing the installer setup
function at the thermostat front panel.
NrSpecialDays There are no special days in this schedule. NrSpecialDays is always zero. Attempts to write another value
causes the write to the file to be ignored.
NrTemps There are no temporary schedules in this schedule. NrTemps is always zero. Attempts to write another value
causes the write to the file to be ignored.

Time1Jan70 Time1Jan70 (nciApplVer) is the time stamp of the last change to the Excel 10 application configuration.
Time1Jan70 meets the ANSI C time stamp requirement specifying the number of seconds elapsed since
midnight (0:00:00), January 1, 1970. It is represented in the Intel format.
nciApplVer identifies the Excel 10 application number, version number and time stamp of the last configuration

User Address Comments
tMaxHtStg Maximum number of heating stages allowed by the subbase.
tNextOcc Occupancy state called for next by the thermostat time-of-day schedule. Occ, UnOcc, Null.
tOCool Equipment output relay  O. True = On; False = Off.
tOff User Mode Switch–Off setting. True= selected; False= not selected.
NOTE: Only one User Mode Switch may be True at a time.
tOKrdwrStPts Future use.
tPgmVer Each thermostat program code version has a PgmVerCode. Each subbase code version is only compatible
with the tPgmVer specifically designed for subbase compatibility. The subbase reads the tPgmVer and checks
for compatibility. If the subbase is not compatible, a tPgmVerAlrm is generated and the Q7300 no longer
communicates with the subbase. If the subbase is compatible, the subbase uses tPgmVer to change its
functionality to be compatible with the software version of the thermostat. The only tPgmVer currently
recognized is 0.
tPump Equipment output relay  Pump. True = On; False = Off.
tReHum Equipment output relay  Relative Humidity. True = On; False = Off.
tSubBaseId Future use.
tSystemState The thermostat internal system state flag. Some of the values are listed in hexadecimal:
A8 = Real time clock is invalid after thermostat startup.
7E = Continuous onoccupied state.
69 = Temporary occupied 9timed bypass) state).
tTAT Equipment output relay  TAT. True = On; False = Off.
tTmpSetPt A temporary setpoint is displayed and used by the thermostat; True = Yes, False = No.
