7.6. DISPLAYING GLOBAL BUILT-IN-TEST (BIT) STATUS
The Global Built-In-Test (BIT) is a 32-bit value that can be configured to store alarm conditions or other
"on/off" or "yes/no" related information. The least significant 8 bits are used internally by ZENOSOFT
®
,
but the other 24 bits are available to store any user-specific "on/off" data.

Since there are up to 32 bits available, ZENOSOFT
®
provides the means for the user to define a unique
name for each bit. This is done in the BIT Names Menu, which is accessible from the System Functions
Menu:
BIT NAMES MENU
(Cn/m) Change Bit n to Value m (Q) Quit
(E) Save Parameters To EEPROM (H) Help
(U) User Menu
BIT Names 1 through 32
Bit 1: ZENO-3200-Reset Bit 17:
Bit 2: Real-Time-Clock-Suspect Bit 18:
Bit 3: Logging-Memory-Initialized Bit 19:
Bit 4: Serial-Sensor-COM-Failure Bit 20:
Bit 5: EEPROM-Suspect Bit 21:
Bit 6: 18-Bit-ADC-Suspect Bit 22:
Bit 7: 12-Bit-ADC-Suspect Bit 23:
Bit 8: Temperature-Clock-Adjustment Bit 24:
Bit 9: Bit 25:
Bit 10: Bit 26:
Bit 11: Bit 27:
Bit 12: Bit 28:
Bit 13: Bit 29:
Bit 14: Bit 30:
Bit 15: Bit 31:
Bit 16: Bit 32:

The first 8 names are predefined since they are the 8 bits used internally by ZENOSOFT
®
. If you want to
change any name (including the first 8), simply use option Cn/m{ENTER} to change Bit Name n to
string m.
Changing a name for a specific bit in the BIT does not affect ZENO

data collection.
Option B in the Test Menu allows you to view the status of the BIT from the previous Sample Interval.
Since the contents of the BIT is dynamic during data collection, only the
value of the BIT from the previous Sample Interval is available to be viewed
using this option.
When you type this option, you will be presented ONLY with the ACTIVE or SET bits in the BIT from
the previous Sample Interval.
