This configuration variable specifies the current application number of

 

 

 

the Excel 10 application.

 

 

 

 

UBYTE, 0 to 255

 

0

This configuration variable specifies the version number of the Excel

 

 

 

10 application.

UBYTE, 0 to 255

 

0

The time stamp of the last change to the Excel 10 application con-

 

 

 

figuration. Time 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 and is four bytes in length.

0

This configuration variable specifies the name of each device. This is

 

 

 

an ASCII string with the a size of 18 characters. A name with all NULLs

 

 

 

means that the device has not been configured.

SNVT_str_asc

 

0x00

This configuration variable is used to provide more descriptive physical

 

 

 

loacation information than can be provided by the Neuron chip's 6 byte

 

 

 

location string.

 

 

 

 

SNVT_temp_p

 

0 s from factory

This configuration variable specifies the maximum time that expires

0 to 6553 seconds

 

 

before the node object automatically transmits nvoStatus. This pro-

 

 

 

vides a heartbeat output that can be used by the destination objects to

 

 

 

ensure that the node is still healthy. The heartbeat output may be

 

 

 

disabled by setting nciMaxSendTime = 0.
